登出后黑屏

[peikona]

各位大侠，小弟在启用受限驱动，并安装上Beryl后，可以实现桌面效果，但是有个问题是：登出就黑屏，好像死机一样，用Ctrl + Alt + F1/2切换到命令窗口都不行，就是黑屏，什么也不显示，只能强制关掉电源再重启，不知道是什么原因。

我的也是这个现象

ATI的显卡？
貌似是很久以前ati官方就确认的bug，一直都未修复

还有，有人提到如果在intel的显卡上错装了ati的显卡驱动也会出这个问题。


罢了罢了，我觉得要长期使用linux的话还是抛弃ati吧，intel和nv都还不错。。。


P.S.万恶的Thinkpad就喜欢用ati卡，郁闷。。想换都不行

这是fglrx的bug报告上找到的

Hardlock on X logout

Up from driver version 8.19.10 you will experience a system hard lock when logging out from X, if the session manager (kdm/gdm) is not properly configured. You have to tell the session manager to restart X.

In the kdm config file (gentoo: /usr/kde/<VERSION>/share/config/kdm/kdmrc) you have to add following to the section [X-:*-Core]:

代码： 全选

TerminateServer=true

In the gdm config (/etc/gdm/gdm.conf) file add the following to the daemon-section:

代码： 全选

AlwaysRestartServer=true

Information from the ATI bugtracker: http://ati.cchtml.com/show_bug.cgi?id=239


Another reason of hardlock my be using the wrong AGP driver. Make sure that you have proper drivers for your motherboard loaded before fglrx: (gentoo: /etc/modules.autoload.d/kernel-2.6):
intel-agp
fglrx

A common problem seems to be mistakenly using ATI Chipset drivers instead of Intel.

在ubuntu的英文论坛上也是找到相同的解决方法

If you suffer from a "white screen" overlayed onto gdm upon logout and the system seizing up, i.e., if you share the Ubuntu system with multiple users, then modify the file /etc/X11/gdm/gdm.conf and either add or change the AlwaysRestartServer option:

代码： 全选

AlwaysRestartServer=true
