我的视频卡工作正常，屏幕没有问题。
我正在尝试生成 xorg.conf，因此我执行了以下操作：
[ Logout ]
sudo service gdm stop
[ Move away xorg.conf.back and xorg.conf.fglrx-0 that were in /etc/X11 ]
sudo dpkg-reconfigure xserver-xorg
sudo X -configure
但是最后一个命令出现段错误：

注意Can't load FireGL DRM library (libfglrxdrm.so)
注意：我确实有文件/usr/lib/fglrx/xorg/modules/linux/libfglrxdrm.so
奇怪的是，它会发生段错误，而我可以毫无问题地使用 Gnome，但是...
可能相关：我最近尝试从 ATI 的网站安装驱动程序，然后 glxgears 在启动时崩溃。
在这些条件下我如何生成 xorg.conf？
它可能涉及或不涉及解决段错误问题。
答案1
如果您使用专有驱动程序，Ati 的驱动程序将为您提供aticonfig负责管理 xorg.conf 的驱动程序。要生成 xorg.conf，请运行：
aticonfig --initial
答案2
您可以使用sudo dexconf -o /etc/X11/xorg.conf
