Intel ARC770M not detected with kernel 6.x

[georgnistor]

Hello,

I have install Zorion Pro version on Intel NUC 12 Enthusiast (Serpent Canyon),
upgraded to kernel 6.4.14 and
I do not have the ARC Video card properly detected.

Does anyone faced the problem? Any clue how to solve it?
thanks

Intel Arc is pretty new. You were correct to advance to the 6.4 kernel to seek driver support, but even so, the xe patch won't be merged into Mainline kernel for another month at the soonest.
You might try (at your own risk - be sure to recall how to use Grub Menu to access Advanced Options for Zorin in case you need to roll back) the Zabbly 6.5 kernel:

16.3 is supposed to have kernel 6.2 but Lite still has 5.15

Yes, it may be helpful for certain users that have very new hardware and need a later kernel. This may also be of benefit when Zorin OS 17 arrives, since TuxInvader mainline kernel is currently for Focal Only. It provides only Unsigned kernels, so they will not work with Secure Boot which may be a deal breaker for some users. NOTE the warning: If your Ubuntu install works great with Ubuntu’s vanilla kernel(s) do not switch to a mainline build idly. If you can’t think of a reason why you ne…

@catlikehana

had this article in my mind

That article does indeed claim "full" support.
Sadly... It's FOSS also erroneously claimed that Zorin OS 16.3 was based on Ubuntu 22.04. They are pop-tech writers...

Reading the Kernel, you have to sometimes follow the merge requests when examining the Latest Hardware in order to get accurate information.
