when i boot my computer after having run an update, my primary monitor (which should be at 1920x1080) is stuck at 640x480. interestingly, when i reboot and change nothing, it fixes itself until i run another update.
i’m on arch, using nvidia 555.58-2, on plasma 6.1.1-1. the monitor in question is DP-0 in the system info below.
what could be causing this and how can i fix it?
i’ve been having this issue for a while while kinda just dealing with it because it was something i could easily work around by booting my computer twice, but i’d really like to get it solved.
system info:
relevant (i think) inxi output

This may be a stupid question. But are you using grub and have nomodeset? Sometimes DE’s have problem with xorg setting monitor settings, which you then half to override somewhere in the init of the DE
–edit
Heres a work around.
https://askubuntu.com/questions/513036/how-do-you-change-display-resolution-of-vmware-player-in-kde-plasma-5#717471
"I have the same issue and have the following workaround:
It is possible to set the resolution from a command line using ‘xrandr’. Running just xrandr allows you to see the current resolution and the other valid resolutions.
From a command line you can run ‘xrandr -s 1024x768’ and the screen in VMware will reset to that size!
You can even set this at KDE startup by doing the following:
click KDE start icon
select System Settings
select Startup and Shutdown
click Add Program…
enter ‘xrandr -s 1024x768’ in the text box
be sure the “run in Terminal” checkbox is checked
follow the rest of the prompts to set it as a startup command.
The next time you log in, it will start at 800x600 but at the end of the login you will see the screen resize!
"
while i appreciate the effort, this has no effect on my issue. also maybe worth noting, i am using grub but not nomodeset. i toggled it on just to see if it would do anything but the problem persists.
if you look at my xrandr output on the first boot, the main problem is that it cannot see any other mode except 640x480 and running
xrandr --output DP-0 --mode 1920x1080fails. i cannot change it using plasma’s display settings gui or xrandr in any way - the only way i know how to get access to the other resolution/rate settings of that monitor is by rebooting.It kinda sounds like some kind of driver issue to me. The fact that it doesn’t detect modes other than a single super basic one sound like not having a proper graphics driver. However, I have no clue why it would work again on reboot and maybe even more importantly, why the other monitor does have a proper mode detected. I wouldn’t expect that if the driver was messed (you would expect all monitors to be assigned some basic mode).
