Describe your issue / feature…

Hello, I’m trying to get my second monitor working, on Arch+Hyprland with a gaming laptop that has two graphic cards (Intel + Nvidia under nvidia-580xx, the only choice left for me since a recent update). The secondary monitor is a 4k monitor plugged on the HDMI port of my laptop (HDMI-A-1 : connected to the Nvidia card)

With this line in the config (and a proper udev rule to symlink the card devices) I can get a workspace displayed on that monitor.

env = AQ_DRM_DEVICES,/dev/dri/nvidia-card:/dev/dri/intel-card

However, most of the apps don’t seem to work anymore (kitty stays black with no prompt, for example) in this config. Everything gets back to normal when I comment the line and reboot, but then nothing appears on the secondary monitor (it is however displayed by hyprctl monitors.). Screen freezes when I try to reach the right border of the default monitor (where is located the external monitor according to the config).

I’m not sure if this is a hyprland issue or a driver config issue. I’m trying here before going to the arch forum.

multi-gpus are a notorious pain, and I don’t own any such devices so I don’t know much. Check here: Multi-GPU – Hyprland Wiki

In general, from what I understand, it’s almost always better to use the iGPU as primary.

I’ve checked this page and accordingly switched back to iGPU as default :

env = AQ_DRM_DEVICES, dev/dri/intel-card:/dev/dri/nvidia-card

However I still have the same issue, no image and lag close to secondary workspace position.

welp, can’t help much then. Might ask around on discord or online, I don’t use multi-gpu, all instructions on the wiki are community-driven
