What I find interesting is that the documentation states that this card (Arc A750/DG2) should support the Xe driver. But when I attempted to blacklist the i915 to see what would happen, I got this message in the system logs:
Adding to my Grub config softlocks the system when the Xe graphics driver loads in, as I would expect.
Fedora 42 is on Linux kernel 6.14.9-300, which is certainly new enough to have really recent drivers.
Code:
[ 1.348108] xe 0000:0b:00.0: Your graphics device 56a1 is not officially supported
by xe driver in this kernel version. To force Xe probe,
use xe.force_probe='56a1' and i915.force_probe='!56a1'Adding
Code:
