Workaround for Lifehacker or gizmodo automatically redirect the browser from .com to .jp

2011-05-08T10:58:00.004+09:00

I sometimes experienced that lifehacker.com or gizmodo.com do redirection automatically to lifehacker.jp or gizmodo.jp. Possibly that the website is either checking the ip address of the user or the browser's local language setting. This auto redirection is quite annoying when accessing the page from google search result, because instead of showing the correct page, it shows the front page of the Japanese version. To solve this annoying redirection, add subdomain "us." in front of the url of lifehacker.com or gizmodo.com page.

For example, if the original URL is:
http://lifehacker.com/5799574/top-10-fixes-for-the-webs-most-annoying-problems

it will become:
http://us.lifehacker.com/5799574/top-10-fixes-for-the-webs-most-annoying-problems

Once the us.lifehacker.com is loaded, it will stay in the English version although we omit the subdomain "us." until we delete the cookies.

How to hibernate instead of standby when closing the lid of macbook(pro|air)

2011-02-28T02:06:00.008+09:00

Sometimes, we probably prefer to hibernate my mbp instead of make it standby when closing the lid. I am wondering why there is no GUI setting for this simple matter. The only way that I know is by using command pmset from the terminal window as follow:

(1) To enable the hibernate:

$ sudo pmset -a hibernatemode 5

(2) To switch back (standby):

$ sudo pmset -a hibernatemode 0

Or for more detail of pmset command, read the manual (man pmset).

How to show full path in Mac OSX Finder window title bar

2011-02-26T13:15:00.007+09:00

To show the complete path in the Finder title bar of Mac OSX (maybe only for OSX 10.5 and newer), type the following two commands in terminal:

$ defaults write com.apple.finder _FXShowPosixPathInTitle -bool YES
$ killall Finder

And to reverse:

$ defaults write com.apple.finder _FXShowPosixPathInTitle -bool NO
$ killall Finder

Windows could not start because the following file is missing or corrupt \windows\SYSTEM32\CONFIG\SYSTEM

2010-12-24T02:07:00.009+09:00

Three days ago, a friend asked me to recover his laptop (winXP) from the following error which always appeared during booting:

Windows could not start because the following file is missing or corrupt \windows\SYSTEM32\CONFIG\SYSTEM

The solution is straightforward from Microsoft website (http://support.microsoft.com/kb/307545). In brief:
The first step is to gain access to windows OS by replacing the broken registry file with the default registry file (windows installation CD is required). The second step is to copy the latest system restore registry file (hopefully your system restore is enabled) to replace the default registry file.

To be more detail, those steps are done as follow:

boot using the WinXP installation CD, select repair

after entering the command prompt, manually copy (overwrite) the registry file (SYSTEM, SOFTWARE, SAM, SECURITY, DEFAULT) from C:\WINDOWS\REPAIR\ to C:\WINDOWS\SYSTEM32\CONFIG\ (you might want to backup the original files)

restart to save mode.

gain access to System Volume Information folder (http://support.microsoft.com/kb/309531/), inside the folder, find sub folder with name _restore {GUID}\RPx\snapshot. For example: C:\System Volume Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}\RP1\Snapshot

copy the following files from the Snapshot folder to any other folders: _REGISTRY_USER_.DEFAULT, _REGISTRY_MACHINE_SECURITY, _REGISTRY_MACHINE_SOFTWARE, _REGISTRY_MACHINE_SYSTEM, _REGISTRY_MACHINE_SAM. Rename each of the files to DEFAULT, SECURITY, SOFTWARE, SYSTEM, SAM, respectively.

boot using WinXP installation CD, select repair

after entering the command prompt, manually copy (overwrite) the file from step (5) to C:\WINDOWS\SYSTEM32\CONFIG\

restart.

finish, or according to the microsoft website, you should try to restore the setting to previous restore point (Start, All Programs, Accessories, System Tools, System Restore, Restore to a previous restore point).

That's all :)

Emulating HASP HL Basic

2010-02-12T17:01:00.009+09:00

About a month ago, I was asked to remove the protection of a software (it looks like the software is specially developed --not for public sale) which is using usb key to protect the unauthorized execution.

First of all, I would like to give credit to the reverse engineering team board, even though I never post any message there, but their board contains invaluable information to help me complete this task. Please notice that I share this information only for educational purpose and only as a note for myself. If you have trouble, please don't ask me. Go to the board instead. :)

Gladly, the usb key type is HASP HL Basic, which is simpler to emulate. Here is the step I've done to successfully emulate the usb key:

Get the password-1 and password-2 of the usb key
Tool required: hasploger
Plug the usb key and run hasploger. Then, execute the protected software. Hasploger will be able to get the password-1 and password-2 of the usb key.
Dump the usb key (password-1 and password-2 from step (1) are required)
Tool required: h5dmp
The size of the dump file is 719 bytes (hasp.dmp)
Create dummy memory file
Tool required: any, notepad text editor is also possible
Since hasp HL Basic does not contain memory, create file with any content with size 112 bytes (hhl_mem.dmp)
Convert the dump file from step (2) and (3) to registry file to be used by emulator
Tool required: UniDumpToReg
Install emulation
Tool required: I am using multikey_19.0.2-x86 to emulate the key in vista (32bit). While in XP I am using vbus_0.15.4.
By using the example of registry file from multikey/vbus, modify the registry file from step (4). Then, install the registry and the emulation tool.
Done.

All of the tools are available freely in the internet, however, it takes time to find.

That's all :)

Update #1 (2010/11/03)

I've just realized that I miss-typed when I checked my files,the correct multikey file that I was using is multikey_18.0.2-x86. Probably there's a new update now since it had been months.

That's all :)

How to set NetBeans locale to English

2009-10-30T00:10:00.005+09:00

My Windows OS has Japanese language as its default locale. However, I am still having troubles understanding Japanese anyway lol. When I try to install JDK+NetBeans, by defaults it will start with the default locale of my system --that is Japanese. After googling here and there, finally found the way to run the NetBeans in English:

Execute the NetBeans with startup parameter --locale:

netbeans --locale en

or

Edit the configuration files (usually in \etc\netbeans.conf), find the entry started with netbeans_default_options="..." and insert the locale parameter to it:

netbeans_default_options="--locale en ..."

How to merge file dll to exe C#

2009-07-25T02:54:00.008+09:00

Today, at work I have to create a demo application using C# to automatically launch IE and open certain URL and modify its form input. Since this task requires SHDocVW and MSHTML components, I have to let dll files accompany the exe file. But there is a requirement that the application shall consist of one single executable. Hence, I have to find a way to merge the dll to executable. Gladly, after searching in the internet, I found that it is very simple.

The step is as follows:

Download ILMerge from microsoft site here.

Install and copy the ilmerge.exe to windows directory or simply make the PATH to installation directory (to let us execute ilmerge.exe from anywhere)

Go to the project properties, Build Events. Assuming the dll files are in the same directory of the Target, enter the following code to the post built even command line:
ilmerge /wildcards /out:$(TargetDir)my-final-app.exe $(TargetPath) $(TargetDir)*.dll

To have a better understanding on how to execute ilmerge, I suggest to read the ilmerge.doc which is located in the installation folder.

how to change gimp language setting

2009-04-16T05:32:00.008+09:00

After changing some regional and language settings in my vista to Japanese, if I run gimp, it displays unreadable character instead of English. I found this url is very helpful to change the language of gimp (in XP, Linux, and MacOSX):
http://docs.gimp.org/en/gimp-fire-up.html#gimp-concepts-running-language

For vista, it is very similar with XP, example is to use English (en):

go to control panel, system, advanced system settings
click Environment variables..
add new environment variable (click New...):
variable name: LANG
variable value: en
Ok. Finish.

That's all :)

Cannot display Hidden Folders and Files

2009-04-02T18:56:00.006+09:00

If you have just infected by some worm or mallware, probably your windows cannot display hidden folders and files although you already set the hidden files options from explorer.
Copy paste the following text to notepad, and save it (for example: repair.reg), then double click to make changes to windows registry.

How to change ubuntu resolution in Virtual Box

2009-03-31T20:42:00.009+09:00

Today, I'm installing Ubuntu 8.04 in Virtual Box, with Vista as the host OS. I'm planning to use it as Qtopia development environment. After the installation is completed, I found that the maximum resolution I could set was only 800x600. After some googling, found the solution as follows:

install linux guest additions in virtual box
1. Select from menu: Devices, Install Guest Additions... Ubuntu will detect a new CD inserted and mount it automatically.
2. go to the terminal, run the VBoxLinuxAdditions.run as root
  $ sudo /media/cdrom/VBoxLinuxAdditions-x86.run

edit /etc/X11/xorg.conf using any text editor you're familiar with.

Find section "Device" as follows:

Section "Device"
        Identifier      "Configured Video Device"
        ...
EndSection

Insert additional setting so that the section "Device" will look as follows:

Section "Device"
        Identifier      "Configured Video Device"
        ...
        Driver            "vboxvideo"
EndSection

Find section "Screen" as follows:

Section "Screen"
        Identifier      "Default Screen"
        Device          "VirtualBox graphics card"
        Monitor        "Generic Monitor" 
        ...
EndSection

Modify value of Device and Monitor, and insert some additional setting before EndSection so that the section will look similar with the following (I set resolution 1024x768 here):

Section "Screen"
        Identifier      "Default Screen"
        Device          "VirtualBox graphics card"
        Monitor        "Generic Monitor"
        DefaultDepth  24
        ....
        SubSection "Display"
            Depth      24
            Modes      "1024x768"
        EndSubSection
EndSection

Finish, reboot.

That's all :)

pppd segmentation fault

2009-03-20T08:19:00.004+09:00

At work, I have to develop an embedded system sh3 with busybox and 2.6.12.6 kernel inside it. It is connected to gsm modem through ttySC1. After shutting down several times and rebooting, the pppd occasionally got segmentation fault. The suggestion from debian bug report solves my problem. It is pretty straightforward: Simply delete /var/run/pppd.tdb file (in my system, it is /var/run/pppd2.tdb).

jwgkvsq.vmx worm/virus RECYCLER folder

2009-02-14T00:54:00.016+09:00

To clean up system which automatically creates autorun.inf and RECYCLER folder with jwgkvsq.vmx, download and run this program. After reboot, the system probably will complain about missing dll file. To fix it manually, you can use regedit or msconfig:

Regedit:

run regedit.exe (start menu, run: regedit.exe),
search the dll file name (CTRL+F)
delete the entry which contains the missing dll file. Usually, the entry should be found on registry location: HKCU\Software\Microsoft\Windows\CurrentVersion\Run\

Or MsConfig:

run msconfig.exe (start menu, run: msconfig.exe),
go to startup tab
Uncheck the Startup Item which contains missing dll file on the command.

To clean up the infected flash disk or external disk with FAT file system, simply delete the autorun.inf and RECYCLER folder. But if it has NTFS file system, windows will complain about having unauthorized access to the file and folder. You can use Linux and mount the NTFS volume (probably it must be mounted forcefully with options -o force), then delete them. Live CD such as Ubuntu will do.

That's all :)

Updated:
If the above cleaning process didn't work (somehow, the above process works perfectly on my PC but has no effect on my friend's), scan the system using this tool. After scanning, there are probably some unaccessible files (check the log file). then:

find suspicious hidden dll file on \windows\system32\,
boot to save mode
change the ownership of the file (right click, properties, security, click advanced.. the rest I expect you know how.. ;) ), then
change the access permissions for everyone,
delete the dll file manually.

Perhaps, step (3) to (5) can be applied to remove the autorun.inf and RECYCLER folder too..

That's all :)

PS. Turn off System Restore and unplug your network before executing the removal tool. Otherwise, the virus might not be cleaned up. And refer to microsoft bulletin here to update the vulnerable patch.

If none of the above methods works for you, perhaps you should try to follow the cleaning process from microsoft knowledge base here.

Zend framework mail: broken kanji

2009-02-07T06:35:00.009+09:00

I'm using Zend framework for most of my web projects at work. One of the must-have features is must be able to send email either scheduled routinely using cron or executed manually from the web. Somehow, I found that on certain web based email clients the contents of the email with Japanese kanji is unreadable.

I'm quite surprised that after doing many trial and errors converting the encoding type, the solution is very straightforward. Simply add a line to the header of the email contains MIME-Version information as follows:

$class->addHeader('MIME-Version','1.0');

But I still don't know why it should be added manually.. :S

disable SELINUX? for smbd.log: Error was Permission denied

2008-10-18T02:39:00.009+09:00

I've just tried to setup another samba for my new linux vmware (I'm using CentOS running on VMWare player). As I already has several linux vmware with samba, I simply copied the samba configuration from other linux which already running.

But.. to my surprised, from the new linux vmware+samba, I cannot mount the samba directory from windows. Checking /var/log/smbd.log, found the following error message:

[2008/10/18 00:26:32, 0] smbd/service.c:make_connection_snum(911)
'/home/user1' does not exist or permission denied when connecting to [remote] Error was Permission denied

I already checked that the directory /home/user1 did exist, the user for connecting was also already had permission to access. After searching for the solution, it seems the problem is related with security enhanced linux policy (called SELINUX ?). Executing man smb_selinux will explain everything what should be done. Well, since this system is only for development, I'm not concerning much for security. The easiest way IMO is by disabling SELINUX at /etc/selinux/config. lol..

SELINUX=disabled

Internet Explorer cannot open the Internet site http://mail.google.com/mail/

2008-05-27T03:16:00.004+09:00

I'm not internet explorer (IE) fanboy, but sometimes I'm still using IE together with firefox. When using IE, if gmail already accessed before, after sign in I often get error message as follows:

Internet Explorer cannot open the Internet site http://mail.google.com/mail/
Operation aborted

The only workaround I found is : by clearing the IE temporary internet files (in IE7: menu Tools, delete browsing history, delete files..), and reload the gmail.

That's all. :)

postgresql ilike for non latin character

2008-05-13T17:08:00.005+09:00

I was having problem with insensitive query of non latin character in postgresql. My postgresql version is 8.2.5, with EUC_JP encoding. However, for temporary solution, I'm using workaround as follows.

Suppose you are having table ABCD with field name: FIELD1 which might contain non latin characters, with database encoding EUC_JP. For example, to search word 'keyword' with ilike in FIELD1, use the following sql:

select * from ABCD where convert(FIELD1 ,'euc_jp','unicode') ilike '%keyword%';

Gimp on Vista: svg.exe has stopped working

2008-04-09T01:13:00.002+09:00

I've just installed Gimp 2.4.5 on Vista. Every time I run Gimp, there're always error message like this:

svg.exe has stopped working

helpbrowser.exe has stopped working

Checking the detail information, seems there's problem with libxml2.dll ( Fault Module Name: libxml2.dll ). Searching from internet, finally found out the workaround:

As administrator, copy libxml2.dll from the bin directory of installed gimp (default will be c:\program files\gimp\bin ) into c:\windows. And don't forget to backup the original libxml2.dll just in case it is required, by simply rename it into any file name, eg: libxml2.dll.original.

That's all.

Cancelling clicked href link in html

2008-03-03T03:57:00.009+09:00

If we want to create a link which is not linked to anywhere but only want to trigger something example as follows:

<a href="#" onclick="alert('test');">...</a>

The page will scroll to the top since the link is nowhere found in that page. To disable the scroll, simply add return false like this:

<a href="#" onclick="alert('test'); return false;">...</a>

<a href="" onclick="alert('test'); return false;">...</a>

How to disable root access from ssh

2008-01-06T20:36:00.001+09:00

By default, usually ssh allow us to login as root. If we are concerned a lot about security, we'll want to disable root access from ssh. Belows are steps to disable direct root access from ssh:

Edit ssh configuration file. Usually the file is located at /etc/ssh/sshd_config

Find the line: PermitRootLogin yes, then replace the line into: PermitRootLogin no

If you'd like to only enable protocol version 2, find the line: Protocol 2,1 then replace it into: Protocol 2

Save the files

restart ssh:
/etc/rc.d/init.d/sshd restart

That's all :)

How to ssh/scp w/o password prompt

2008-01-05T20:47:00.003+09:00

Sometimes, we'd like to automate a file transfer process between main server and backup server. We can use scp to transfer files but usually scp requires input for password prompt. Belows are quick steps to remove the password prompt for scp/ssh.Basically, there are two steps needed:

create public and private key in the ssh client
copy or append the public key content to the ssh server

If you are using SSH version 2, follow the following steps:

at the client machine, login as the user who will execute the ssh or scp, then create pair of public and private key using dsa to ~/.ssh/id_dsa with the following command:
$ ssh-keygen -t dsa -f .ssh/id_dsa
(If there's a prompt asking for password, leave it blank. There will be two files created on ~/.ssh/ : id_dsa (private key) and id_dsa.pub (public key))
Copy or append the content of id_dsa.pub (public key) above to the ssh server at the home directory of the ssh user: ~/.ssh/authorized_keys2

If you are using SSH version 1, follow the following steps (very similar):

At the client machine, login as the user who will execute the ssh or scp, then create pair of public and private key using rsa to ~/.ssh/id_rsa with the following command:
$ ssh-keygen -t rsa -f .ssh/id_rsa
(If there's a prompt asking for password, leave it blank, there will be two files created.)
Copy or append the content of id_rsa.pub (public key) above to the ssh server at the home directory of the ssh user: ~/.ssh/authorized_keys

That's all :)

Update:
Don't forget to set the file permission for the public key file in ssh server:

chmod 600 ~/.ssh/authorized_keys or chmod 600 ~/.ssh/authorized_keys2

That's all :)

How to get yesterday time

2008-01-03T21:06:00.002+09:00

Sometimes, we need to create a simple script in linux which involves retrieving system time several days/hours/minutes ago.

Belows are example use of date command:

To get yesterday time:

$ date --date="1 days ago"

$ date --date="-1 days"

To get one month ago:

$ date --date="1 months ago"

$ date --date="-1 months"

To get one hour ago:

$ date --date="1 hours ago"

$ date --date="-1 hours"

To get one minutes in the future:

$ date --date="+1 minutes"

To get one seconds in the future:

$ date --date="+1 seconds"

We can also combine it, example to get one month and two hours ago:

$ date --date="1 month 2 hours ago"

$ date --date="-1 month -2 hours"

There are many other ways to express the particular time.

That's all :)

Bash keyboard shortcut

2008-01-02T21:32:00.002+09:00

Below is list of keyboard shortcut for bash shell.

Why we need keyboard shortcut? The short answer is: to save time!
Especially, when we are accessing bash remotely (eg: by ssh) and the network access pretty slow, we will need a keyboard shortcut such as deleting the entire command line, moving to the beginning of the command, etc to save a lot of time.

Below are some of keyboard shortcuts for bash. Maybe in certain conditions it does not work properly.

ALT + b : move the cursor backward one word.

ALT + f : move the cursor forward one word.

ALT + d : cut one word after the cursor.

ALT + u : uppercase one word after the cursor.

CTRL + a : go to the first character of the line.

CTRL + b : move back one character.

CTRL + c : Sending signal SIGINT the current process you run (usually the process will be killed).

CTRL + d : Sending EOF, Exit/logout the current shell.

CTRL + e : go to the last character of the line.

CTRL + f : move forward one character.

CTRL + h : clear one character before the cursor. (similar with backspace)

CTRL + k : cut all characters after the cursor.

CTRL + l : clear screen.

CTRL + r : search for previously used commands.

CTRL + t : swap the last two characters before the cursor.

CTRL + u : cut all characters before the cursor.

CTRL + w : delete one word before the cursor.

CTRL + y : recall the last cut character by CTRL+u or CTRL+k or ALT+d (just like paste)

CTRL + z : put the current process you run into background process. To restore it, use command fg.

ESC + t : swap the last two words before the cursor.

TAB : autocomplete command/files or folders name.

That's all :)

Ubuntu Dapper Drake + XGL + Compiz + Acer Aspire 5502 Part 2

2006-07-05T00:32:00.000+09:00

All right folks, now I'd like to share what I've done to enable XGL and compiz to my aspire 5502. FYI, acer aspire 5502 is using ATI X-700 as it's VGA card with screen resolution 1280x800.

At the beginning of running Dapper Drake CD installer, all I got was only blank screen on Graphics mode. I had to switch to console, using sudo, and edited /etc/xorg.conf to enable viewing the graphics on the LCD screen.
At the Section "Device" I added:

Option "MonitorLayout" "LVDS,CRT"

And voila.. I could see the GUI but the resolution only worked at 640x480. I've tried dpkg-reconfigure -phigh xserver-xorg but still the same. Well, nevermind, from http://ubuntuforums.org/showthread.php?t=204910, I got a clear step to install fglrx 8.26.18 (the latest ATI proprietary driver for now). Here's the step I've done:

0. make sure having the latest ubuntu packages

sudo apt-get update
sudo apt-get dist-upgrade

(I also update my kernel into the latest one)

1. download the ATI driver file from
https://www2.ati.com/drivers/linux/ati-driver-installer-8.26.18-x86.run

2. Edit /etc/apt/sources.list to enable universe and multiverse repository (actually I enable all repository, lol)

3. install some necessary tools:

sudo apt-get update
sudo apt-get install module-assistant build-essential
sudo apt-get install fakeroot dh-make debconf libstdc++5 gcc-3.3-base

and from synaptic package manager, I also install linux-header and linux-headers-386 (I think it's needed by ATI proprietary driver, because without installing it, the installation of ATI proprietary driver was failed)

4. continue the walkthrough from http://ubuntuforums.org/showthread.php?t=204910, that is to create deb package:

chmod +x ati-driver-installer-8.26.18-x86.run
./ati-driver-installer-8.26.18-x86.run --buildpkg Ubuntu/dapper

5. install the package:

sudo dpkg -i xorg-driver-fglrx_8.26.18-1_i386.deb
sudo dpkg -i fglrx-kernel-source_8.26.18-1_i386.deb
sudo dpkg -i fglrx-control_8.26.18-1_i386.deb

6. compile the kernel module:

sudo module-assistant prepare,update
sudo module-assistant build,install fglrx
sudo depmod

7.finish. Just need to update the xorg.conf file:

sudo aticonfig --initial

then I edit manually the xorg.conf :)

To make sure everything is on the correct way, running fglrxinfo, I got message looks like this:

display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON X700 Generic
OpenGL version string: 2.0.5879 (8.26.18)

Now onto the installation of compiz.. Based on the walkthrough I found at http://www.compiz.net/viewtopic.php?id=389 and http://www.tectonic.co.za/view.php?id=916, I follow the combination steps from both url before it works for my laptop:

0.Edit /etc/apt/sources.list, adding repositories for compiz:

deb http://www.beerorkid.com/compiz/ dapper main
deb http://xgl.compiz.info/ dapper main
deb-src http://xgl.compiz.info/ dapper main

1. download and import the gpg key for quinnstorms repository

wget http://www.beerorkid.com/compiz/quinn.key.asc -O - sudo apt-key add -

2. update apt packages again:

sudo apt-get update

3. install the compiz related packages:

sudo apt-get install compiz xserver-xgl libgl1-mesa xserver-xorg libglitz-glx1 compiz-gnome

4. create file .Xsession and save it into /home/{$user}
The contains is like this (I copy paste directly from http://www.tectonic.co.za/view.php?id=916)

#!/bin/sh
# Start up Xgl, compiz, and GNOME
# Run Xgl server on :1, on top of normal X
Xgl :1 -fullscreen -ac -accel xv -accel glx:pbuffer &
# Tell subsequent X programs to access the Xgl server at :1
DISPLAY=:1
# Start Compiz window manager
gnome-window-decorator &
compiz gconf decoration wobbly fade minimize cube rotate zoom scale move resize place menu switcher &
# Start GNOME
exec gnome-session

5. Finish.

That's all... When I tried to create new user account for my ubuntu, I should create .Xsession to run Xgl server on :2 (not :1), so the .Xsession for the 2nd user should be like this (I ommit the comment line):

#!/bin/sh
Xgl :2 -fullscreen -ac -accel xv -accel glx:pbuffer &
DISPLAY=:2
gnome-window-decorator &
compiz gconf decoration wobbly fade minimize cube rotate zoom scale move resize place menu switcher &
exec gnome-session

Now I'm quite happy with my "pretty funny" ubuntu. ;)

Ubuntu Dapper Drake + XGL + Compiz + Acer Aspire 5502

2006-07-03T23:44:00.000+09:00

Last weekend, I was very anxious to see how good is XGL, so I search any howto for installing xgl and compiz to linux ubuntu.

I got many helps from compiz forum and ubuntu forum.

Here is the step to enable XGL+compiz on my Acer Aspire 5502 and Ubuntu dapper drake.

1. Make sure 3d graphics already enabled
just make it easy.. I got the howto in here:
http://www.ubuntuforums.org/showthread.php?t=204910

2. Installing compiz+xgl
I got the walkthrough in here:
http://www.compiz.net/viewtopic.php?id=389 (the 2nd howto) and
http://www.tectonic.co.za/view.php?id=916

Later on, if I'm not lazy, I'll post the summary, so you can see the detail what I've done.
