Intel NUC 12 Enthusiast Kit with Arc 770 and fedora 39

[Gianluca Cecchi]

Hi,
a friend of mine has an Intel NUC 12 Enthusiast Kit (NUC12SNKi72) with an
Intel Arc 770 graphic card installed on it.
By default fedora 39 anaconda freezes (black screen after skipping verify
media and selecting install option).
It seems the same scenario as described here for fedora 37:
https://kevinquillen.com/getting-intel-arc-770m-work-fedora-37
Before going through all the same steps I would like to test something
shorter, especially without disabling ACPI and PCIe Power mgmt in the bios,
if possible in latest Fedora.
Suggestions for anaconda boot parameters?
Eg
1) using nomodeset option at installation phase. Could it work oob?
2) any way to specify an option for a kernel module during install? WHat
syntax?
I mean the equivalent of using the
options i915 force_probe=5690
in /etc/modprobe.d/i915.conf for an already installed system

BTW: I have still to understand if the system will use both graphics cards
(which one is primary in this case?) or if the onboard one will be disabled
if using a discrete card on the Nuc.
Thanks in advance,
Gianluca

I've no idea what will happen with a NUC, but in my experience Fedora
will use the discrete card in preference to the IGP, unless it's
blacklisted in the boot line.

There's a package called switcheroo-control which allows you to select
which GPU to use for specific apps, though personally I haven't had
much luck with it.

No sure this is what you're looking for, but:

you can edit the kernel parameters in the boot entry.
Select a boot entry from a list and press 'e' to edit. Then 'ctrl+x' to execute.
That way, you can have a custom kernel option set while running the
Fedora installation ISO.

If that would help with the freezing during Anaconda installation, you
should be halfway there.

Then after installation is finished, on the new system, edit
`/etc/default/grub`, which is used when a new boot entry is added,
which is usually done by some Post scriptlet of the kernel, when you
(re-)install / update the kernel.
I did this in the past to solve different issues requiring edit of
kernel parameters.
e.g:
echo "GRUB_CMDLINE_LINUX="intel_idle.max_cstate=2 i915.enable_psr=0
i915.enable_fbc=0"" >> /etc/default/grub

For example the settings in the /etc/default/grub I use, are:
GRUB_TIMEOUT=1
GRUB_DISABLE_UUID=true
GRUB_ENABLE_BLSCFG=true

Hope this helps.
