I just changed my screen for a better one. Right now my resolution is 2560x1440, when I open nvidia-settings and switch to 3840x2160 and apply I get a black screen.
I tried reinstalling the nvidia drivers with sudo mhwd -f -i pci video-nvidia, but no luck.
arandr
You might have some success using xrandr to set your desired resolution.
sudo pacman -S xrandr
(if not already installed)
Or, as the previous poster probably meant to express: ARandR: Another XRandR GUI, which is a gui version of xrandr.
sudo pacman -S arandr
I hope this helps. Cheers.
Same with xrandr / arandr, 3840x2160 is listed as an option, but when I apply it I get a black screen.
You might try using xrandr outside the GUI, via a TYY, the procedure for which is outlined in this unrelated article. Then reboot.
Being that I don’t use i3wm, I can’t offer anything overly constructive. I’m also not aware of the current status of Wayland in i3wm, however, that might be worth investigating.
I’ll chime in again if I think of anything useful. Cheers.
sway is the wayland version of i3.
Unfortunately I also get a black screen when I try to enter TTY using Ctrl Alt F4.
Not super familiar with Wayland or Sway, are those needed for higher resolutions ?
Which are the relevant log files I could look at after getting a black screen to try to find out what’s going on?
Strictly, no. However, when using other Display Environments, Wayland can sometimes make a difference, mainly due to much developer attention to it in recent times as opposed X11.
As mentioned above, Sway is the i3 version of Wayland, and there is conveniently a separate Sway distribution. Whether it will ultimately make much difference in your case, I can’t say.
Some users have claimed choosing a different cable (eg: DP to HDMI) has produced results in similar situations. Naturally, that’s wasted money if it fails to make a difference.
Changing your kernel could also produce positive results, as this Arch user found. If you haven’t updated recently, the latest iteration of kernel 6.6 might be worth trying; either that, or the latest 6.1.x LTS.
Thank you, I installed the 6.6.8-2 kernel. After rebooting and changing the resolution I still got a black screen, but now after another reboot it seems to work, I don’t think I changed anything else. Strange issue…
Also, I have to change the resolution manually after each boot, it doesn’t seem to save eventhough it’s set properly in /etc/X11/xorg.conf.
Well, you’re halfway there, it seems.
@cscs might be able to give some insight on retaining that resolution; having it survive a reboot; or at least, have a few thoughts on the matter.
It might be an idea to post the content of your xorg.conf, in case it’s helpful.
I don’t use Nvidia or high resolution monitors (and not i3 either), so I’m not likely much help from this point forward. Cheers.
Check and update the Nvidia driver to the latest version compatible with your hardware.
And I havent seen a physical nvidia in half a decade at least. (still wasnt mine)
That said.
Please put configurations in /etc/X11/xorg.conf.d
ex: /etc/X11/xorg.conf.d/custom.conf
As always it makes sense to get general system info
