First tests with Intel Tiger Lake (11th Gen) show the same
symptoms. This in the end would mean we can't ship stock Leap 15.2
anymore. Which I would wan't to avoid if possible.
I'm afraid that
you'll need quite lots of other package upgrades for
supporting the new hardware on top of the stock Leap 15.2. e.g. the
sound won't work on many recent machines and the upgrades of alsa-*
packages are needed. I guess the same applied for the graphics.
As Leap 15.3 alpha got available today I tried in on an Ryzen/Renoir
and on a Tiger Lake based machine. Both worked fine ootb, which is
So, are there any chances those things necessary will be backported to
Leap 15.2 as well?
I don't think we'll backport those to Leap 15.2 as official updates.
Leap 15.2 was already released, and it's simply new hardware that
wasn't covered by Leap 15.2, which is no "bug" per se.
But we definitely need some better support for the new hardware before
the official Leap 15.3 release (which will be still far away).
Might be worth to set up a repo to carry (or rebuild) a set of chosen
packages from Leap 15.3 for 15.2? Then user don't need to update the
full packages at each time, at least.
Just my $0.02.
