Hi,

My setup:
Fedora 37 (Wayland), with KDE 5.27
(A) 2560x1440 monitor
(B) 1440x900 monitor
Nvidia GeForce 3060 Ti, connected to (A)
Intel Arc A480, connected to both (A) and (B)

Description:
I want to create a VFIO gaming setup, with Fedora KDE as my Linux host. So the Intel Arc needs to output video and becomes my main desktop GPU because the Nvidia card will be unavailable to Fedora later (passed into the Windows VM).
However, adding and enabling the 2 video outputs of the Intel Arc failed. Can anyone guide me on troubleshooting this?


What I have done:
1. dnf upgrade and installed akmod-nvidia driver
2. Enabled Intel Arc drivers with i915.force_probe modprobe option
3. In the display setting menu, all three video outputs (1x Nvidia, 2x Intel) are listed. I tried to enable the two video outputs of the Intel Arc, but nothing happened after clicking apply. The configuration are lost after I refresh the display setting menu.

Expected result:
All three display connections are enabled successfully.
