Intel Arc / Fedora won't load graphics card on boot

Ask Fedora

Running on Fedora rawhide, kernel 6.1, I cannot get Fedora to load the Intel Arc / Intel integrated graphics devices on a cold boot.

Fedora will seemingly freeze just before the loading screen / login. It gets down to the point of ‘force_probe … tainting kernel’ and then proceeds no further.

I have set the WaylandEnabled=false setting in gdm conf, and I have also added an i915.conf under /etc/modprobe.d that has:

options i915 force_probe=5690

I have also added the latest Intel gpu firmware to /lib/firmware/updates/i915. The logs below indicate they are used.

Still, the only way I can get into Fedora on a cold boot is by editing grub2 and setting nomodeset. Once I am inside, I check the logs for anything mentioning VGA, guc, huc, and there is nothing.

If I reboot at this point and log back in (still nomodeset), then I start to see the GPU in lspci:

lspci -nnv | grep -i "vga"
00:02.0 VGA compatible controller [0300]: Intel Corporation Alder Lake-P Integrated Graphics Controller [8086:46a6] (rev 0c) (prog-if 00 [VGA controller])
03:00.0 VGA compatible controller [0300]: Intel Corporation DG2 [Arc A770M] [8086:5690] (rev 08) (prog-if 00 [VGA controller])

At this point, if I edit grub2 conf and remove nomodeset, then reboot, the GPU is loaded and I am using the device (Settings indicates the card is in use, and does not say Software Rendering). However, here are some logs that look curious regarding HuC/GuC and I do not know what they mean or if they contribute to this issue:

[   10.776214] i915 0000:00:02.0: [drm] GuC error state capture buffer maybe too small: 2097152 < 2360316 (min = 786772)

[   10.967837] i915 0000:03:00.0: [drm] GuC RC: enabled

At this point, I can reboot as much as I like and the GPU will be used. However, if I shutdown, then power back on, Fedora freezes again and I have to revert back to nomodeset. I have also tried enable_guc=2 and enable_guc=1 in i915.conf - the problem still persists.

What is the difference here between a cold and warm boot in regards to device discovery / driver loading? Is something extra needed for this to work from a cold boot? I feel like I am close to getting this working but its driving me crazy.

How did this poster get it to work on Fedora? I am using an Intel NUC 12th gen alder lake. I have seen a few other posts of people getting it to work without any mention of this sort of problem. They are doing the force_probe method, which sounds like most people are - but it is being really problematic for me. I’d even be happy at this point just to have the integrated graphics loaded if I can’t use DG2/Arc for a few months.

Relevant dmesg on a warm boot when i915 is loaded. On cold boot, the process freezes just before the i915 line(s).

But its fine with this on a reboot (i915.force_probe). Thoughts? The first i915 device is the integrated graphics, the second device is the A770 GPU.

Hello Kevin.

As far, as I understand, must intel arc a770 run on Wayland session to work, else it will not start!
I self have many issue with the Intel Arc A770 16GB Limited Edtion, and even intels own solution, to run Ubuntu ect, do not work for me, I don’t know if that is doing to my AMD CPU?

I have try Arch iso, direct install, It run, but I don’t get access to drivers, give errors on vainfo.
I normal run EndeavourOS, and same there.
Only OS, that works like it should is (sadly for me) Windows.

So today I will try Fedora Workstation with Gnome (I really, like REALLY don’t like gnome at all)
but I also know that KDE Plasma and Wayland do not work good with either Nvidia nor this intel gfx card, so what else is there to try ?

I have also tested that force.probe, don’t make any change, and the I can’t get access to HuC on the card, so it might be on intel CPU that allow it?

I got AMD Ryzen 9 5900X.

Ohhh I forgot, I don’t know if your nuc have Resizable BAR or not, but that MUST be enabled, and also CMS must be turned off, accorded to intels page.

Read about it here: Ubuntu* 22.04 (jammy) — Intel® software for general purpose GPU capabilities documentation

Sadly, it seems they only support Ubuntu for now, I REALLY hope (soon) we on other distro can work with this card. I can’t afford to buy another one anytime soon.

(Sorry for the above mess… I got autism + ADHD)

Oh another thing, you also must use modesettings!
and for the modprobe.d/i915.conf = options i915 enable_guc=3 (I think you shall use 3, since you got alderlake cpu)

Even that you run Fedora, you can benefit from this: Hardware video acceleration - ArchWiki

Also this: Intel graphics - ArchWiki

Hope I can help you a little.

I started over from scratch. I also updated my NUC bios, and disabled ACPI/PCIe power management in the BIOS. That did the trick for me (including i915.force_probe), YMMV. I wrote up my steps here, and I have been doing work from the new NUC/F37 all week without a single issue.

Unlike other machines folks have here, the NUC is very specific and the BIOS are tuned for it being an end to end machine. I have no such BIOS options for 4G decoding, enable rebar, etc, I assume they are already enabled (I guess theyd have to be, since my GPU works).
