After login, monitor still acts funky


I was foolish enough to try another garuda-update and my monitor started doing funky things again, literally the same thing as before.

Described a little better, it goes like this. I reboot on either zen or lts kernel, and i'm presented with the login screen on both monitors. I login, and immediately the ASUS monitor (my primary) reads No Signal regardless of if i'm using HDMI or DisplayPort. I go into Display Settings and try to activate it. It doesn't read an input.

What I did last time to fix it is not working.

Last edit:
works with HDMI alone, does not work with both HDMI and DP plugged in. DP alone also does not work. I'd like to use the monitor with DP because it's the only input that does 165hz.

I sadly don't have any ideas to contribute as I'm not experienced with this type of issues, but I certainly appreciate the effort put into these threads :slight_smile: hope someone has an idea :blush:


Lol! i don't have a choice unfortunately. I need 3 monitors to do what i'm doing for research, and i have exactly 1 hdmi output that i now have to use for my main monitor instead of my annotation tablet.

Sad day. :frowning:

Thanks for your support anyhow! :slight_smile:


Try switching to Wayland and see if you have better luck.

...Wait a second...

...Déjà vu, anyone? :joy:

After fully updating:

sudo pacman -S plasma-wayland-session

You will have to add the modesetting kernel parameter (Nvidia :roll_eyes:).

sudo micro /etc/default/grub

On the GRUB_CMDLINE_LINUX_DEFAULT= line, add nvidia-drm.modeset=1 to the other kernel parameters on the line. Save and exit, then:

sudo update-grub

Reboot, and find the cog wheel on the login screen to change to a Wayland session.


Willing to try anything at this point, will report back! THANK YOU!

Now i'm getting some weird compositor issues that i didn't have before, and my mouseover tooltips are appearing on the side of the screen.

And discord won't even show... I need that for my study group. I will have to go back to X11.

EDIT: switching back to x11 made it mysteriously work again... i'm sure this isn't the last i've seen of DP bug.

I found out that Wayland is great at one thing on nvidia machines. THe issue happened again today, so i logged out, logged back in on Wayland, adjusted monitor settings, then logged back in on X11.

I want to see this happen a few more times and ensure this is a fix before i call it a solution/workaround.


:thinking: Hmm, I don't think that is the intended use of Wayland. :rofl:

I'm glad it's helping, even if it is in an odd, very hacky way. I'm curious what is happening on the back end that seems to jostle the display back into working.

This has to be a hardware, or a driver issue. I definitely don't know enough about any of that to even begin to troubleshoot it. It exists on multiple kernels if so...

I haven't tried other window managers outside of VMs though. Maybe that's the next step. I don't really have time to "agile" this though, move fast and break stuff.

Happened again after my computer autolocked my screen. Absolutely wayland works as a workaround for this bug.

I've been having this issue as well. I posted a reply on this thread with a workaround that has worked reliably for me. Also, manually disabling sleep/screen locking in power management prevents this from happening again while I'm using my desktop. This issue seems to happen whenever the screen goes to sleep.
