Double Login Screen

Issues & Assistance Newbies
1

Since a recent update, the login screen appears double (on HDMI external monitor). It shows up on the screen as usual, then a 2nd copy of the login screen shows up in the upper-left corner, which looks really odd. After login, the spinning icon also shows double, then the double disappears and I'm on the desktop as normal.

But if laptop goes to the lock screen and I come back, then I have screen clipping problems, where the mouse can extend way outside the screen, making it hard to find my mouse and hard to use the bottom shortcuts bar.

Please check if this tutorial helps:

It is strange indeed that the issue is occurring only now, of course.
In my opinion it could be an issue due to the recent long-awaited sddm update to release 0.20.
Anyway, just give it a try if you want.
I’ve seen also this similar old (again, strange) sddm issue:

but it’s unsolved…
Actually, a comment from an Arch user links (as solution) to this Arch Wiki article/chapter:
https://wiki.archlinux.org/title/SDDM#Overlapping_greeters_on_multiscreen_setup

Thanks, I added the script to Xsetup. Unfortunately, the problem remains.

Both internal displays and TV are 1080p. On login, the login page appears with very large text on the internal display, and small in the TV corner.

4

Also note that if I put only the internal display in /usr/share/sddm/scripts/Xsetup, it still behaves the same displaying double-login on the login screen.

xrandr --output eDP-1-1 --auto --primary

Login screen isn't really a problem. What's more annoying are mouse boundary problems after I leave the computer for a while. I'm not exactly sure when that happens. If I close the TV off and on, it's fine. If I go back to lock screen, turn TV off and on, it's fine.

But if I leave the computer for a while... then the mouse stops being constrained to the lower-left corner, and there are also V-Sync issues when watching videos.

This; combined with the OpenCL problem, make for a very irritating experience right now.

5

Considering the proposed solution doesn't work, it seems like a different problem that in the GitHub threat?

Anyone seen any further information on this issue? It seems SDDM multi-monitor issues have been lingering for a very long time.

6

After unplugging the monitor, I realize I have a much bigger problem: the recognition of the internal display went completely bunkers. That's what causes the other issues.

I have a 1080p 144hz display.

As you can imagine, it's not behaving optimally. Rebooted with linux-zen kernel. How do I make Garuda come back to its senses regarding the internal display? Smash it a few times? It may be drunk...

I'm starting to think the Intel OpenCL issue may be related to this somehow.

I removed the ALHP packages.

It fixed the Intel OpenCL problem, but the other display problems remain.
