USB-Cを介してi3をウィンドウマネージャとして実行しているArch Linuxシステムに外部モニタを接続する際に、この奇妙な問題が発生しました。
私の設定は、USB-C（マイコンピュータも充電する）を介して接続されたドッキングステーション、Lenovo Thinkvision T27hv-20とThinkvisionにデイジーチェーンで接続されたDellモニタです。
xrandr / DPを介して接続されているモニターを表示できますが、xrandr --autoまたはxrandr --output DisplayPort-x --autoはモニターを起動しません。 HDMIケーブルとアダプタを介して接続すると機能します。
ケーブルの問題を排除できます。他のコンピュータ（kali linux）でうまく機能します。
正式にはアイデアが足りません。同じ問題を経験した人はいますか？

非同期ロールオーバーを無効にしてこの問題を解決しました。私はこのファイルを作成し、/etc/X11/xorg.conf.d/20-noasyncflip.conf
これを追加しました：
Section "Device"
Identifier "Device0"
Driver "modesetting"
Option "PageFlip" "off"
EndSection
クイック再起動後：
sudo systemctl restart display-manager.service
（または再起動すると）問題が修正されました。
私の問題は、カーソルを見ることができ、システムを起動してから数秒間すべてが正常であることです。解像度を更新するときに機能することもありますが、1つのモニター（2つの外部モニター）にのみ適用されます。
