今日、私はデスクトップを開き、見苦しい低解像度ディスプレイに会いました。設定を確認すると、1024 x 768または800 x 600の2つのオプションのみが利用可能になりました。
以前は約20のオプションがありましたが、私は1920 xの一部を使用していました。
私はPOP!OS 20.04 LTSを実行しています。
/var/log/apt/history.log を確認し、以下を発見しました。
Start-Date: 2021-03-28 09:43:04
Commandline: apt-get --allow-downgrades -y install pop-upgrade libpop-upgrade-gtk
Upgrade: libpop-upgrade-gtk:amd64 (0.1.1~1608137131~20.04~d3bfb98, 0.1.1~1616430952~20.04~7df32bb), pop-upgrade:amd64 (0.1.1~1608137131~20.04~d3bfb98, 0.1.1~1616430952~20.04~7df32bb)
End-Date: 2021-03-28 09:43:08
試して再起動$ sudo apt-get --allow-downgrades --reinstall install pop-upgrade libpop-upgrade-gtkしましたが、役に立ちませんでした。
私もそうでした：
sudo apt clean
sudo apt update -m
sudo dpkg --configure -a
sudo apt install -f
sudo apt dist-upgrade
sudo apt autoremove --purge --remove --purge

アイデアが足りません。どんな助けでも大変感謝します。
修正する
「derpmatt」のおかげでchat.pop-os.org誰が私に指摘したのかこのソリューションこれでログインの問題が修正されました。しかし、まだ他のユーザーのログインを変更し（各ユーザーとしてログインせずに）、まだ4歳のログインのように見えるログイン画面を変更する方法を探しています！
他の多くの投稿が提案したように~/.config/monitors.xmlファイルをにコピーし/var/lib/gdm3/.configて所有者をに変更してみましたが、gdmこれは私のコンピュータに何の影響もありませんでした。
よろしくお願いします。
