Hi all, I've been using Garuda Linux on my laptop for about a week now with no issues, however a couple of days ago I ran into an issue where my external monitor started showing up as connected, but isn't displaying anything. I found that running xrandr --output HDMI-0 --mode 1920x1080 followed by xrandr --output HDMI-0 --mode 2560x1440 resolves this temporarily, but every time the display turns off, e.g. restart, sleep, or locking, I have to do this again. I don't encounter the issue on my Windows or Ubuntu partitions either. Any pointers on troubleshooting/resolving this would be greatly appreciated. inxi -Faz output:
This is telling that you’ve not been updating lately, since zen kernel is at 5.15.12 since the 29-Dec-2021. Although this is contrast with:
So, this was probably not due to an update.
On the contrary, if you installed something a couple of days ago, you could try restoring a previous snapshot.
Anyway, maybe you could update now, considering that in the meanwhile xorg-server was updated (you never can say, maybe this could help).
Apart from that, I don’t have experience in multi-monitor setups, but maybe I can pass you the two releant Arch Wiki articles. https://wiki.archlinux.org/title/Xrandr https://wiki.archlinux.org/title/Multihead
Hi Filo, thanks for the reply! Unfortunately updating didn't do the job. I looked over the documentation you linked and it prompted me to look over the xrandr output though, and there's some stuff that looks weird there.

My laptop screen's width seems to be getting picked up at 4480, which is actually my external monitor (2560) plus the laptop's actual width (1920). I'm not sure if this is expected, so if anyone else has any experience I'd greatly appreciate advice.
Update after investigating this more: the issue seems to be a combination of the refresh rate and the resolution. If I have my monitor set to 1440p@60hz it's able to display without issue, however at 120 or 144 it doesn't. If I change the refresh rate from 144/120 to 60 while the monitor is connected but not displaying, then revert the change, it works without issue though, in the same way changing the resolution does. This issue also doesn't occur when I've got it set to [email protected]. The reason this was working fine for the first week was because I was using the other HDMI cable plugged into my computer, which was only allowing up to 75hz. I've looked through a lot of similar reports on the Arch/Majaro forums and haven't found any solutions that work, or anything that is an actual match to this issue.
Hopefully there's enough info now for someone to have a better idea of what could be wrong - I've been trying to resolve this for over a week now and haven't made any headway.
