我在一台配备 960m 显卡的 ASUS ZX53VW 笔记本电脑上使用 Ubuntu MATE。我安装了专有的 NVIDIA 驱动程序版本 387.34。
当我打开 NVIDIA X 服务器设置时，出现一个弹出窗口：
You do not appear to be using the NVIDIA X driver.
Please edit your X configuration file (just run `nvidia-xconfig` as root),
and restart the X server.
我按照所述运行 nvidia-xconfig 并得到以下结果：
Using X configuration file: "/etc/X11/xorg.conf".
Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'
但是当我重新启动 lightdm（或重新启动）并尝试再次打开 NVIDIA X Server Settings 时，我遇到了同样的问题。xorg.conf 如下所示：
# nvidia-xconfig: X configuration file generated by nvidia-xconfig

看起来它无法识别显示器。事实上，如果我运行 sudo get-edid | parse-edid，我会得到：
This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
Looks like no busses have an EDID. Sorry!
Attempting to use the classical VBE interface
Performing real mode VBE call
Interrupt 0x10 ax=0x4f00 bx=0x0 cx=0x0
然后它就挂在那里了。我猜想这台显示器似乎没有通过 EDID 识别自身。
这个问题导致我只能使用 800x600 分辨率。有什么办法可以解决这个问题吗？
