検索してみると、正反対の問題を解決したい人だけが見つかりました。
私はArch Linuxを実行しており、ウィンドウマネージャとしてi3を使用しています。画面ロックを処理するためにi3-lockを使用しています。画面をロックできますが、モニターがスリープ状態にならず、i3-lock の空の画面が永久に表示されます。
[関連]出力は次のとおりですxset q。
DPMS (Display Power Management Signaling):
Standby: 300 Suspend: 300 Off: 1800
DPMS is Enabled
Monitor is On
これは dpms 設定を宣言する i3config の一部です。
exec --no-startup-id xset dpms 300 300 1800
exec --no-startup-id xss-lock --transfer-sleep-lock -- i3lock --nofork
私はAMD 6950XTを使用しており、以下は（関連）出力ですlspci -v。
