经过一些相当高级的配置和内核编译后，我在我的 MacBook Pro 8,3 上启用了 EFI 启动和 Intel Graphics，并且禁用了 ATI 专有驱动程序，以便能够节省大量电量并使笔记本电脑在此过程中保持更低的温度下。
但是，我似乎无法lightdm开始。我/etc/X11/xorg.conf看起来像这样：
Section "Device"
Identifier "Device0"
Driver "intel"
BusID "0:2:0"
EndSection
我删除了所有内容以允许内容或多或少地自动配置，但我想确保 X 尝试加载英特尔驱动程序而不是其他任何东西。
在我的 中/var/log/lightdm/lightdm.log，我看到以下内容：

似乎无法启动欢迎程序，但没有比这更详细的信息了。我似乎找不到任何其他相关日志。在 中Xorg.0.log，我看到此错误：
[ 477.378] (EE) GLX error: Can not get required symbols.
我不知道这是否与此问题有关，但确实如此。您对 lightdm 无法启动的原因有什么想法吗？我能够让 X 本身启动sudo startx，但欢迎程序无法启动 :(
答案1
fglrx仍然在安装是罪魁祸首。更好的从轨道上用核武器轰炸它：
sudo apt-get remove fglrx*
