-- Information about the crash:
I have my monitors set to sleep after a certain amount of time. I also have the session set to log out a certain time after the screens are off. I came back to my computer today, after the night, and kwin crashed as soon as I moved the mouse to turn the screens back on.

I have a dual monitor system connected via display port, with one monitor rotated 90 degrees.

Git commit 9dd70310eb016625313a0e81b6b49e98e64fff6a by Xaver Hugl.
Committed on 24/02/2025 at 21:49.
Pushed by zamundaaa into branch 'master'.

backends/drm: reject output configurations that can't be powered at all

Just disabling pipelines doesn't work, as the outputs are still enabled in that
case and will try to present on the disabled pipeline, causing crashes.

This fixes https://crash-reports.kde.org/share/issue/bbe74a0e4b494c929f8f52bca6a0953b

workspace: better deal with having more outputs than the GPU can drive

Instead of just giving up, when generating a new output configuration we just disable
outputs one by one. This *should* result in an output configuration that can actually
be enabled, and it's up to the user to then change the set of enabled outputs to what
they like to have.

backends/drm: reject output configurations that can't be powered at all

Just disabling pipelines doesn't work, as the outputs are still enabled in that
case and will try to present on the disabled pipeline, causing crashes.

This fixes https://crash-reports.kde.org/share/issue/bbe74a0e4b494c929f8f52bca6a0953b

Looks like this issue is still reproducible Plasma 6.3.2

For me (reporting in 500942), the issue even started with 6.3.2. It did not appear before the upgrade to 6.3.2 today (2 march 2025).
I had run updates less than a week before that.

According to the version history shown at the link below, it seems that the previous version that worked was 6.3.0-3, so what worked in 6.3.0 broke when upgrading to 6.3.2-1.

The regression is slightly different from the original bug report, and tracked in bug 500819. Let's leave this original issue as fixed
Comment 15 Nate Graham 2025-03-31 19:09:52 UTC 
Xaver, We just got a bug report from someone using 6.3.3 (Bug 502156) that looks like it has the same backtrace. What shall we do?
Comment 16 Nate Graham 2025-04-11 18:30:27 UTC 
And another one in bug 502268. Re-opening.
