monitor configuration restored incorrectly upon Wayland login

[Jonathan Kamens]

I have an ultrawide monitor plugged into my laptop. When I log into a Wayland session, my monitor configuration (resolution, relative position, which monitor is the primary) is not restored correctly. When I unplug the monitor cable after logging in and plug it in again, the correct configuration is restored.

Thank you for your bug report. Could you test if the issue exists under X?
It looks like an upstream bug, could you report it there

I am no longer able to reproduce this issue so I'm going to close it.

I take it back, it just happened again. Apparently it's intermittent.

I can't determine for certain whether it happens under X, because (a) as I just noted, it's intermittent, and (b) my monitor has an entirely different issue under X, see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1849484 .

Could you report the issue upstream?

Thanks

I'm not sure treating bug 1849484 separately to this one is the right answer. Although it's understandable that Wayland and Xorg sessions will exhibit different behaviour and different bugs, the common factor is still the same hardware and kernel. So it still sounds like a hardware or kernel problem. Therefore a common problem between the two bug reports.
