Just install kernel-vanilla package from the standard Leap 15.0, boot with vanilla kernel and retest. It corresponds to the unpatched 4.12.14, while Leap kernel contains lots of i915 backports that is almost equivalent with 4.16. If kernel-vanilla is OK, it's likely a regression by the backports. -- You are receiving this mail because: You are on the CC list for the bug.

As you can see in dmesg, there is Oops in nouveau during boot. The problem goes away if I blacklist nouveau module or use kernel-vanilla, even suspend/resume starts working! I completely forgot the laptop had nvidia chip as I almost never use it :) But anyway, I'll stick with kernel-vanilla for now, because with nouveau blacklisted laptop does not shut down nvidia chip, which drains battery greatly. -- You are receiving this mail because: You are on the CC list for the bug.

Thanks, this is a very helpful information!

I'm building a test kernel with the possible fix backport in OBS home:tiwai:bsc1094751 repo. Once after the build finishes (it'll take an hour or so), the kernel package will be available at http://download.opensuse.org/repositories/home:/tiwai:/bsc1094751/standard/

Please give it a try.

It looks like build service is experiencing publishing problems again, so I did a local build of a kernel from you repository. No more black screens for me, thanks! Suspend/resume works too. -- You are receiving this mail because: You are on the CC list for the bug.
