xrandr: Failed to get size of gamma for output default
xrandr --addmode Screen 0 "1280x1024_60.00"xrandr: unrecognized option '1280x1024_60.00'
因此，虽然它说这是一个无法识别的选项，但运行 xrandr 将显示新模式：
Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 640 x 480, maximum 640 x 480
default connected 640x480+0+0 0mm x 0mm

v: height 1024 start 1027 end 1034 total 1063 clock 59.89Hz
我完全不知道 addmode 会添加到什么，因为 xrandr 已经列出了模式，但 addmode 只是失败，并且不知何故最大值仍然是 640x480。正如你所看到的，我是在 21 英寸屏幕上以小得离谱的分辨率进行写作的。
自从我尝试安装 nvidia 驱动程序以来，我一直徒劳地试图找到解决方案，所有解决方案都以某种方式让我失败。
我正在使用拱门。
更新：nvidia-xconfig 生成一个conf 文件，使系统无法启动到登录屏幕。我必须删除它并运行 startx 才能到达这里。我想 Xorg.0.log 中关于此的相关部分是：

另外，运行 nvidia-settings 会出现此错误：
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.
答案1
您的发行版是哪个？版本是什么？
一些 Nvidia 发行版存在一些限制。
对于 304.xx 等旧版驱动程序，我建议使用 Debian 而不是 Ubuntu，因为从 Bionic Beaver 18.04 开始，该驱动程序缺乏对该驱动程序版本的支持。
答案2
好吧，显然，如果您安装最新的 nvidia 驱动程序而不是您应该安装的驱动程序，就会发生这种情况。完全违反直觉，但似乎我需要 304.xx，而不是我实际上首先尝试过的较新的其他版本。
