Description Jürgen Groß 2021-01-24 06:41:24 UTC
System was inactive for some time, so screens were going to power save mode. After moving the mouse only two of my 3 screens became alive again, the third one remained black.

In messages I see:

The affected monitor is connected to the docking station (via thunderbolt)

I couldn't shut down the system normally when it happened the first time, it would hang. At the second incident I let the system just sit there and in the next morning it was unusable, even network access wasn't possible.
Comment 1 Takashi Iwai 2021-01-24 08:05:30 UTC
I don't think that this warning itself could lead to more severe problem like the freezing.  It may indicate a tip of the iceberg, of course, but no direct cause.

Which X driver is used?  modesetting or xf86-video-intel?  (I guess the former, but just to make sure)
Comment 2 Jürgen Groß 2021-01-24 11:36:40 UTC
I'd say this is modesetting, according to X.log:

Comment 3 Takashi Iwai 2021-01-29 19:53:43 UTC
Thanks.  Yes, it looks like the modesetting being used.

The error reminds me of an old issue with DP-MST, happening with two monitors.

You can try openSUSE-15.2 KOTD in IBS Devel:Kernel:openSUSE-15.2 as lots of DRM fix patches have been backported recently, although I don't think this bug is covered by those.

BTW, how is this bug reproducible?  Does it happen always, or only very occasionally?
Comment 4 Jürgen Groß 2021-01-30 06:12:44 UTC
Haven't seen it since the original report.
Comment 5 Miroslav Beneš 2022-02-11 12:15:35 UTC
Juergen, anything new here? Leap 15.3 has a newer stack so it may have been fixed in the meantime.
Comment 6 Jürgen Groß 2022-02-11 12:28:40 UTC
(In reply to Miroslav Beneš from comment #5)

I haven't seen it since updating to 15.3 some months ago.

I'm fine to have this bug being closed.
Comment 7 Miroslav Beneš 2022-02-11 12:35:02 UTC
Thanks for the feedback. Closing.
