我在一台配备独立 NVidia 显卡（GeForce 610M）的笔记本电脑上全新安装了 Xubuntu 20.04。我根本没有修改视频驱动程序设置（除了在安装时启用专有驱动程序）。
问题是 GLX 不起作用：
holyblackcat@hbc-laptop:~$ glxinfo
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig
以下是 Xorg 日志：
holyblackcat@hbc-laptop:/etc/X11$ grep -i nvidia /var/log/Xorg.0.log

我尝试运行sudo nvidia-xconfig并重新启动。
它并没有解决 GLX 问题，而使得事情变得更糟：系统切换到了一个很小的分辨率，即使删除/etc/X11/xorg.conf（由 生成nvidia-xconfig）并重新启动后我也无法更改它。
我目前已切换到 Noveau 驱动程序，它解决了这些问题。
答案1
请卸载全部nvidia 驱动程序然后安装仅有的最新的一个。
