因此，我之前安装了 Nvidia 390.12 驱动程序，并想将其恢复为 384.11。我这样做了$ sudo apt install nvidia-384（清除后nvidia-*）并重新启动，结果分辨率只有 3:4。我这样做了，$ xrandr但显示无法检测到我的 DVI 端口：
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768

v: height 1080 start 1083 end 1088 total 1177 clock 143.88Hz
请注意，我cvt 1920 1080 144之前确实创建了一种新模式（我有一个 144Hz 显示器，它与 390 驱动程序一起工作）。
然后我$ xrandr --addmode default 1920x1080_144.00又重复了$ xrandr一遍，得到：
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768

1024x768 76.00*
1920x1080_144.00 143.88
关闭终端并重新打开它，不知何故它现在显示
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1920 x 1080
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 76.00*
1920x1080_144.00 143.88
请注意，最大值已升至 1080p。尝试从显示管理器 GUI 设置模式并得到此结果。
另外，需要注意的是，为了以防万一，我尝试关闭 UEFI 的安全启动。但没成功。
最后我想检查一下 monitors.xml，发现设置来自“默认”部分。将其更改为 1920 x 1080，并设置刷新率，重新启动，最终变为 1080p。很棒，对吧？好吧，现在在深色背景下，东西似乎有点闪烁。另外，我$ xrandr再次运行：
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384

现在它似乎可以检测到我的 DVI 输出，这很好，尽管我不确定为什么会这样。在此之前我重启了很多次，所以我不认为这是重启的问题。我还按照一些互联网人士的说法安装了nvidia-settings它nvidia-current，以便让它$ nvidia-xconfig工作（仍然无法运行$ nvidia-xconfig— 显示“未找到命令”），所以这可能改变了一些东西。
无论如何，在较暗的背景下（奇怪的是，在白色和中灰色上看不到这一点），屏幕明显闪烁，就像它快速变暗然后恢复正常。然后我尝试$ xrandr -r 144（因为它说我仍然处于 60Hz 状态）。屏幕按预期变黑，然后它弹道然后开始闪烁，颜色很暗，然后恢复正常。它看起来也不像黑屏，更像是屏幕上有一个半透明的黑色覆盖层，快速闪烁。当我说快速时，我的意思是迅速地. 比如，会诱发癫痫。
我惊慌失措地打字（没有看我的屏幕，因为它抽搐了）$ xrandr -r 60然后它恢复正常，我只能看到较暗背景上的轻微闪烁（例如 Discord）。
我检查了 monitors.xml，没错，我的输入的刷新率为 144，所以我不确定它默认为 60 是怎么回事。然后我尝试创建一个刷新率为 144 的新模式，然后将其设置为我的输出模式。然后我的显示器在黑色背景前显示“超出范围”。我硬关机并重新打开它。
现在我决定用一些游戏来测试。我启动了一款通常有 144+ FPS 的游戏（我将其限制在 140，这样就不会出现撕裂）。现在我得到了30-45帧每秒。我已经使用 384 驱动程序和这个精确的设置，没有任何问题——尽管上次我是使用 Nvidia 网站上的 .run 安装的，而不是从包管理器中安装的。

编辑：好的，经过一番搜索，我发现在 中/etc/modprobe.d/blacklist.conf，有一个nvidia被列入黑名单。我删除了它并重新启动，当我启动到 Ubuntu 时，屏幕现在开始闪烁。我从恢复模式启动，不知为何，它起作用了，在恢复模式下，我不再遇到这个问题。一切都正常显示，我可以将其设置为 144Hz。所以我想我已经解决了名义上的问题，但现在我必须从恢复模式启动。至少我现在有一个解决方法，我想？
答案1
因此，问题在于包含/etc/modprobe.d/blacklist.conf。nvidia删除它并重新启动后，该问题自行解决。
