我的笔记本是
宽屏的
ATI Mobility Radeon 9200 的老显卡,32MB的显存,
好不容易开启了特效,可是显示不正常,
选1024x768模式会把屏幕拉伸到填满整个屏幕
可选1280x800却变成了1024x768的显示,右边一块黑了
而且窗口最大化之后的标题栏一片空白,文字,按钮都看不到
重启之后上下两条面板也空白了,一个按钮都看不到
这是怎么回事啊
哪位大侠能帮帮我

自己搞定了
在ubuntu的外文网上找的的解决方法
大概是这样做的:
If you previously used the proprietary "fglrx" driver it is highly recommended to totally get rid of the fglrx package:



$ sudo apt-get remove --purge xorg-driver-fglrxand reboot the computer.



The libGL.so in /usr/lib might also still be the version installed by xorg-driver-fglrx. You can check that very easily, just run:



$ glxinfo |grep vendorIf you see: client glx vendor string: ATI, then the libGL.so is still from ATI. Make sure libgl1-mesa-glx and libgl1-mesa-dri are properly installed:



$ sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-driOf course, make sure your xorg.conf does not contain any "fglrx" entry.



Configuring X.org


sudo vim /etc/X11/xorg.conf
or

sudo nano /etc/X11/xorg.conf
Configuring your graphics card "Device" section

You first of all have to find the device section already related to your graphics card. It can have any name, or might even not exist if you are just installing your xserver. You can usually find it right after your mouse entry.



It should look like this:



Section "Device"

Identifier "Radeon 9200"

Driver "ati"

BusID "PCI:1:0:0"

Option "XAANoOffscreenPixmaps"

EndSection



The "Monitor" section

This is what your monitor section should look like:



Section "Monitor"

Identifier "Generic Monitor"

Option "DPMS"

HorizSync 28-72

VertRefresh 43-60

EndSection


The "Screen" section

It will basically look like that:



Section "Screen"

Identifier "Default Screen"

Device "Radeon 9200"

Monitor "Generic Monitor"

DefaultDepth 24

SubSection "Display"

Depth 24

Modes "1280x800"

EndSubSection

EndSection



For cards low on video RAM, you might need to add a "Virtual" line to the "Display" subsection of the "Screen" section in xorg.conf, since the default values (see /var/log/Xorg.0.log) are a bit "greedy" on memory.



Virtual 1280 800
Set the x and y values according to the wanted maximum size of your virtual desktop.



Finalizing

Add the following sections at the end of the file if they don't exist elsewhere:



Section "DRI"

Mode 0666

EndSection



Section "Extensions"

Option "Composite" "Enable"

EndSectionThen check the "ServerLayout" section:



Section "ServerLayout"

Option "AIGLX" "true"

Identifier "Default Layout"

Screen "Default Screen"

InputDevice "Generic Keyboard"

InputDevice "Configured Mouse"

EndSection
The AIGLX option is to enable AIGLX for fancy 3D desktop effects. Identifier should not be changed. Screen is the name you gave to your screen in the screen section. InputDevice are for the devices you want to use (with a section device in this file) and which are not your graphics card or monitor.



Restart and get a new accelerated desktop!
