Intel Arc B580 driver issues on Ubuntu

[Shahin51]

Dear intel Support team,

I have recently upgraded my Arc A750 to Arc B580 and since the upgrade i face issues with Ubuntu.

Arc750 was working fine on Ubuntu 24 and after i upgraded to B580 i faced driver issues.

I did follow the guide on https://dgpu-docs.intel.com/driver/client/overview.html and attempted to install new drivers however packages failed couldn't fix this.

Screen is flickering every few minutes randomly confirming driver comparability issues !

Then i decided to upgrade Ubuntu to 25.10 which is recommended for native support however issue persists.

Error messages are:

$sudo dpkg --configure -a
