Missing /dev/dri/renderD128

[digitalgimpus]

Missing my iGPU with kernel 6.8.12-5pve. Running 13th gen which seems should be supported.

root@pve:~# ls -la /dev/dri/renderD128

gives me nothing

dmesg | grep i915

gives me nothing

lspci does show the device, so it's enabled in BIOS:

00:02.0 VGA compatible controller: Intel Corporation Raptor Lake-S GT1 [UHD Graphics 770] (rev 04)[/CODE

lsmod...
[CODE]# lsmod | grep i915

modprobe:

# grep i915 /etc/modprobe.d/*

/etc/modprobe.d/i915.conf:options i915 enable_guc=3

Looking deeper in dmesg:

I'm kinda stumped.

If it helps, you're not the first: https://forum.proxmox.com/threads/d...pear-when-switching-to-kernel-6-8-4-3.148798/
You could try what's described here in chapter 5.6. It's about using different Xe driver, which can be used only, if usage is forced.

That looks very similar. Thanks. At least that's something to go on.
