所以之前我安裝了 Nvidia 390.12 驅動程式並想恢復到 384.11。我用$ sudo apt install nvidia-384（清除後nvidia-*）執行此操作並重新啟動，結果解析度為 3:4。我這樣做$ xrandr，說它無法檢測到我的 DVI 連接埠：
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 76.00*
1920x1080_144.00 (0x27b) 452.500MHz -HSync +VSync
h: width 1920 start 2088 end 2296 total 2672 skew 0 clock 169.35KHz
v: height 1080 start 1083 end 1088 total 1177 clock 143.88Hz
請注意，我cvt 1920 1080 144之前創建了一個新模式（我有一個 144Hz 顯示器，它與 390 驅動程式一起使用）。
然後我一次又一次地這樣做$ xrandr --addmode default 1920x1080_144.00，$ xrandr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
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 76.00*
1920x1080_144.00 143.88
關閉終端並重新打開它，現在以某種方式顯示
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
請注意，最高可達 1080p。嘗試從顯示管理器 GUI 設定模式並得到了這個。
另外，請注意，為了以防萬一，我嘗試從 UEFI 中關閉安全啟動。沒有骰子。
最終我想檢查一下monitor.xml，發現該設定來自「預設」部分。將其更改為 1920 x 1080 並設定刷新率，重新啟動，終於是 1080p 了。太棒了，對吧？好吧，現在在黑暗的背景上，東西似乎有點閃爍。另外，我$ xrandr又跑了：
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384

現在它似乎可以檢測到我的 DVI 輸出，這很棒，儘管我不確定為什麼會這樣。之前我重啟過很多次，所以我不認為這是重啟。我還安裝了nvidia-settings並nvidia-current按照一些互聯網人士所說的方式進行$ nvidia-xconfig工作（仍然無法運行$ nvidia-xconfig- 說“找不到命令”），所以這可能會改變一些東西。
不管怎樣，在較暗的背景上（奇怪的是在白色和中灰色上看不到這一點），螢幕明顯閃爍，就像它很快變暗然後恢復正常一樣。然後我嘗試$ xrandr -r 144（因為它說由於某種原因我仍然處於 60Hz）。螢幕按預期變黑，然後就消失了彈道的並開始閃爍，然後恢復正常。它看起來也不像黑屏，它更像是我的螢幕上有一個半透明的黑色覆蓋層，它快速閃爍。當我說快速時，我的意思是迅速地。例如誘發癲癇。
我嚇壞了，打字（沒有看我的螢幕，因為它太亮了）$ xrandr -r 60，它恢復正常，我只能在較暗的背景上看到輕微的閃爍（例如 Discord）。
我檢查了 Monitors.xml，是的，我的輸入刷新率為 144，所以我不確定預設為 60 會發生什麼情況。 然後我嘗試創建一個刷新率為 144 的新模式，然後將其設定為我的輸出模式。然後我的顯示器在黑色背景前顯示“超出範圍”。我執行硬關機並重新開啟。
現在我決定用一些遊戲來測試。我啟動的遊戲通常具有 144+ FPS（我將其上限設為 140，這樣就不會出現撕裂）。現在我得到了30-45 幀/秒。我已經使用了具有這種精確設定的 384 驅動程序，沒有出現任何問題，儘管上次我確實使用 .run 從 Nvidia 網站而不是從套件管理器安裝它們。

編輯：好的，經過一番搜索，我看到/etc/modprobe.d/blacklist.conf，有人nvidia被列入黑名單。我刪除了它並重新啟動，當我啟動到 Ubuntu 時，螢幕現在開始閃爍。我從恢復模式啟動，由於某種原因該模式可以工作，在恢復模式下我不再遇到問題。一切顯示正常，我可以將其設定為 144Hz。所以我想我解決了名義問題，但現在我必須從恢復模式啟動。我想至少我現在有一個解決方法？
答案1
所以這個問題是/etc/modprobe.d/blacklist.conf包含的nvidia。刪除並重新啟動後，此問題自行解決。
