Bug Description

Running a fresh install of Ubuntu 24.06 (ie not an upgrade from 23.10). Graphics card is NVIDIA GeForce RTX™ 3060 with 5120 X 1440 Samsung monitor. Configuration behaves as expected on xorg but switching to Wayland on login gives display resolution at ? X 1080. Settings application crashes under Wayland.

Until release of 24.06 this machine was running 23.10 which did not exhibit this problem.

I thought to try adding a new user which would have fresh configuration files. This new user experienced the same or very similar problems (xorg session screen resolution seems fine, wayland session screen resolution is ? X 1080).

On first login (which was an xorg session) the screen resolution was set to 3840 x 1080. I used the Settings application to change it to 5120 X 1440. The resolution did not change at that point, but when I logged out and logged back in again, it was at that point 5120 X 1440.

So I infer from this (perhaps wrongly) that the problem is not caused by some crufty old configuration file.

Also, the Settings app reports two monitors for both users, when only one is connected. Not sure why.

Thanks for linking to https://bugs.launchpad.net/bugs/2060268. Solved my "ghost monitor" problem; I will report my experience on that bug.

Relative to the screen resolution - when I added the boot flag mentioned there to /etc/default/grub, rebooted and logged into an X (not Wayland) session, my screen was back to 3840 x 1080. However, when I went into Settings and changed the resolution to 5120 X 1440, this time the screen blanked briefly, then returned in the higher resolution and asked if I wanted to keep the setting. I selected "yes" and I continue to have the desired resolution as long I as I am using X.

However, logging into a Wayland session, my screen resolution is back to 3840 X 1080, and I still cannot run the Settings to try to change the resolution (the Settings icon appears briefly in the dock, then vanishes, and no apport is offered).

Another observation: looking at the GNOME login screen, I'm pretty sure it's in 3840 X 1080 mode as well (or at least, not in the higher resolution supported by this monitor), as the info on the screen appears larger than I recall it from April in 23.10.
