Not getting full refresh rate on mulit-monitor setup

[DizzieNight]

I just setup hyprland on arch on my framework 13 laptop. I use an eGPU on my desk for my 2 monitors, one being a 1080p60 monitor and the other being a 1440p240 monitor. The 1080 monitor is fine and so is the integrated display but my 1440p240 monitor is running sub 60hz. I tried kde to test and it was running at the full 240hz.

I used wlr-randr and DP-6 is the monitor I'm having problems with and it seems that there are 2 modes preferred, the one I want is current but using the computer and by the glxgears output that is not true.

It seems like there is something I'm missing or hyprland doesn't work great with eGPUs? I'm not too sure and was wondering if anyone could help.

Here is some evidence and config below:

hyprland.conf file

monitor=eDP-1,preferred,0x1440,1.566667
monitor=HDMI-A-1, preferred,auto-left,auto,transform,3
monitor=DP-6,2560x1440@240,0x0,1

what gpu is your hyprland running on? My guess is your integrated one which cannot push 240hz for obvious reasons.

[DizzieNight]

Yeah that's a good point, would you know how I could check or even force hyprland to use my egpu? When I test with kde then it works perfectly so maybe kde just picked it up when hyprland doesn't

[vaxerski]

check AQ_DRM_DEVICES in https://wiki.hyprland.org/Hypr-Ecosystem/aquamarine/#variables

IDK how KDE works, but it could use split rendering. We don't.

[DizzieNight]

Sorry if this is a stupid question but where do I put the aquamarine variables in the .conf file? I tried in the general section and also tried a new aquamarine section but both of those came up with an error saying the config option doesn't exist

[DizzieNight]

I got it working. I read the doco properly like I should have and put it in as an env variable. If anyone else has this problem I did it like so:

env = AQ_DRM_DEVICES,/dev/dri/card0:/dev/dri/card1

Thank you so much vaxerski, it's made hyprland so much better for my setup
