大约一个月前，自动更新和七天不重启的连续性不知何故破坏了我的图形功能，导致我只能使用 Unity 2D 并且无法玩视频游戏。我怀疑这与驱动程序版本或内核模块未加载有关。
请帮忙。 ：）
我尝试过
安装/重新安装、、nvidia-331和其他，重新启动多次。nvidia-331-updatesxserver-xorg-video-nouveau-lts-quantal

我按照规定运行了命令。似乎没有发生任何变化，我仍然在 Unity 2D 中，而我的测试用例游戏（GBA rom 上的 mednafen）报告 GLX 仍然损坏。
结案lightdm报告如下：

命令
lspci -v
将告诉您每个适配器正在使用什么驱动程序。看起来您现在只使用 i915 英特尔显卡。
如果内核模块 nvidia 没有加载...使用 CTRL + ALT + F2 进入文本会话，使用您的用户名和密码登录，然后输入以下命令：
sudo service lightdm stop
（如果您使用 gdm，请用 lightdm 替代 gdm）
sudo modprobe nvidia
sudo service lightdm start
请发布任何错误。
好的尝试：
sudo apt-get install --reinstall xserver-xorg-core
如果这不起作用，请备份并删除 /usr/lib/x86_64-linux-gnu/xorg/extra-modules/libglx.so 并重新启动
