Issue description

I have a script to switch between my desktop monitor and my TV screen, which uses xrandr :

# ...
xrandr --output "$MONITOR" --off --output "$TV" --auto --primary
# ...
qtile cmd-obj -o root -f restart

I use it all the time, and it used to work with qtile. But after some update, I now get a black screen, with only my mouse cursor visible. Switching back to my desktop monitor does not solve the issue, and I have to close qtile and launch it again.

I have seen #4886, but adding a second screen to my config did not change anything.

Do you know what might cause this issue ?

If qtile crashed, it probably logged something somewhere. Can you look in the logs and see?

Nothing in my qtile logs. Qtile doesn't crash, as my mouse cursor still moves. It even changes into a caret if I spawn a terminal using my qtile shortcut, indicating that qtile still works behind the black screen.

Interestingly, quitting qtile with the lazy.shutdown() shortcut removes the black screen for a very short moment before actually quitting.

Well, I'm dumb. I didn't know about the reconfigure_screens setting. Why it worked before and ceased working only a couple weeks ago, I don't know. But it works now, and I apologize for the waste of time.
