xrandr --addmode Screen 0 "1280x1024_60.00"xrandr: unrecognized option '1280x1024_60.00'
そのため、認識できないオプションが表示されますが、xrandrを実行すると新しいモードが表示されます。
Failed to get size of gamma for output default

xrandrがすでにモードをリストしているので、addmodeが何に追加されるのかわかりません。しかし、addmodeは失敗し、何とか最大値はまだ640x480です。ご覧のとおり、私は21インチの画面で非常に小さな解像度で書いています。
nvidiaドライバをインストールしようとした後、解決策を見つけようとして無駄にしようとしましたが、すべて失敗しました。
私はアーチを使っています。
アップデート：nvidia-xconfigは、システムがログイン画面から起動するのを防ぐconfファイルを生成します。ここまで来るには、それを削除してstartxを実行する必要がありました。私の考えでは、Xorg.0.logの関連部分は次のとおりです。

また、nvidia-settingsを実行すると、次のエラーが発生します。
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.
答え1
あなたのディストリビューションは何ですか？バージョンは何ですか？
一部のNvidiaディストリビューションにはいくつかの制限があります。
304.xx などの従来のドライバでは、Ubuntu の代わりに Debian を使用することをお勧めします。 Bionic Beaver 18.04以降、このドライババージョンのサポートが不足しているためです。
答え2
さて、インストールしたいドライバの代わりに最新のnvidiaドライバをインストールすると、これが起こります。完全に直観に反していますが、実際に最初に試した他の最新バージョンの代わりに304.xxが必要なようです。
