我非常幸运地拥有一台相当牛逼的显示器——Mitsubishi Diamond Pro 740 SB

那么，/etc/X11/xorg.conf显然就不同于普通的泛泛之辈了。

HOWTO: Change Resolution/Refresh Rate in xorg

Test Configuration without Restarting X

sudo xinit -- :2

One can see the result on a new X (ctrl+alt+F9) without losing the first. If something goes wrong, one can easily use the backup configuration under their surviving X (ctrl+alt+F7).

最近在公司的laptop上尝试也ubuntu一把，结果输入法怎么也搞不定，按照之前写的文章的设置可以安装，但是无法在en_US的Locale下用Ctrl+Space激活。

输入im-switch -s scim_xim -z default之后，系统会显示No alternatives defined，于是发现在en_US的Locale下一定要把输入法安装到这里面才可以，那么正确的命令就应该是：

sudo im-switch -s scim_xim -z en_US

3D-Desktop is an OpenGL program for switching virtual desktops in a seamless 3-dimensional manner. The current desktop is mapped into a fullscreen 3D environment where you may choose other screens. Several different visualization modes are available. A window manager compatible with the GNOME pager standard is required.

The transition from working desktop to fullscreen 3D environment is seamless: when the pager activates you see your current desktop appear to zoom out to a point in space where you can see your other virtual desktops allowing you to select another.

The program is rather memory-hungry and it is CPU intensive, but it's accessible from the command line, which makes it perfect for show floors and impressing your non-UN*X-using friends.

在官方注解中出现这样的描述略搞笑了……

先搞定显卡驱动，NV或ATI。

删除compiz，如果先前安装过的话。

在/etc/apt/sources.list里面添加：

deb http://www.beerorkid.com/compiz dapper main

然后运行：

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

之后就可以安装软件了：

sudo apt-get update
sudo apt-get dist-upgrade 
sudo apt-get install xserver-xgl libgl1-mesa xserver-xorg libglitz-glx1 beryl emerald-themes

接下去略重要，需要启动XGL，略参考：https://help.ubuntu.com/community/CompositeManager/Xgl

已经有牛人简单归纳了一下需要修改的内容：

NV的：
sudo gedit /etc/gdm/gdm.conf-custom，在[servers] 后面加入
0=Xgl

[server-Xgl]
name=Xgl server
command=/usr/bin/Xgl :0 -fullscreen -ac -accel glx:pbuffer -accel xv:fbo
flexible=true

ATI的：
sudo gedit /etc/gdm/gdm.conf-custom，在[servers] 后面加入
1=Xgl

[server-Xgl]
name=Xgl server
command=/usr/bin/Xgl -fullscreen -br -accel xv:pbuffer -accel glx:pbuffer -dpi 100 -nolisten tcp
flexible=true

sudo gedit /etc/gdm/gdm.conf

找到“0=Standard”，改为“1=Standard”；找到“GdmXserverTimeout=10”，改为“GdmXserverTimeout=50”（这句的功能据说只是延长timeout时间，增加成功机会 -,= ）。

最后把beryl-manager加入启动项即可。 System->Preferences->Sessions->Startup Programs

sudo gedit /etc/fstab

我的文件内容：
