Description Iakov Karpov 2018-05-26 11:26:10 UTC

I've upgraded openSUSE Leap 42.3 to 15.0 on my laptop.
After the upgrade, if I choose to shut down Plasma session either with logout command or by killing XOrg, the screen goes dark and computer stops responding keyboard commands.

I use 'modesetting' xorg driver. If I install the xf86-video-intel driver, the screen goes dark even before that, while logging into KDE.

The GPU is 2nd gen sandybridge. I'm not sure what other info I can provide. It's possible to ssh into computer while the screen is dark.

Comment 1 Takashi Iwai 2018-05-26 11:51:52 UTC

One thing you may check quickly is to test kernel-vanilla package.
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.

Comment 2 Takashi Iwai 2018-05-26 11:54:29 UTC

Also, if you can access via ssh, please get the kernel messages after the hang happens.  Get the output of "dmesg" command.  If it's a GPU hang, usually the kernel shows it.

Last but not least, try to boot with drm.debug=0x0e option, and get again the kernel messages at the problem.  This will give more verbose debug prints from the kernel graphics stack.

Please attach these outputs to Bugzilla (not paste :)

dmesg of kernel-default + drm.debug=0x0e

Comment 5 Iakov Karpov 2018-05-26 14:00:16 UTC

Apparently, it was the fault of nouveau, not i915. 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.

Comment 6 Takashi Iwai 2018-05-26 22:18:26 UTC

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.

Comment 8 Takashi Iwai 2018-05-27 11:48:37 UTC

Good to hear!  I pushed the fix patch to my SLE15-UPDATE branch so that it'll be merged back to openSUSE-15.0 update later.
