Hi,
I considered it a one off, but it now happened a second time so I thought it
might be worth to report so you can match against anything else you might get
reported.
## Setup
- Ubuntu 24.04 with mostly defaults (I config a few things but e.g. do
not install a massive amount of extensions or such)
- Lenovo T580
- GPU UHD Graphics 620
- DisplayLink Plugable USBC-6950 Dual HDMI Adapter
- 5 Screens left to right
- top row: 1: laptop display, 2: full HD on displaylink, 3: full HD on
displaylink
- bottom row: 4: full HD on DP of the docking station, 5: full HD on DP of
the docking station
- 1: is the primary screen (e.g. with the dock)
- 4: is the screen with issues at least the 2/2 times it happened so far
- In xrand terms it is
DP-4 connected 1920x1080+514+1920 (normal left inverted right x axis y axis)
600mm x 340mm
DP-5 connected 1920x1080+2434+1920 (normal left inverted right x axis y axis)
600mm x 340mm
eDP-1 connected primary 1920x1080+0+840 (normal left inverted right x axis y
axis) 340mm x 190mm
DVI-I-1 connected 1920x1080+3000+840 (normal left inverted right x axis y
axis) 600mm x 340mm
DVI-I-2 connected 1080x1920+1920+0 left (normal left inverted right x axis y
axis) 600mm x 340mm
- $ echo $XDG_SESSION_TYPE
wayland
## Situation:
#1 first time
24. Sept
- Right at the moment when I tried to screen share through meets the screen
(4) froze up
- froze to me means the content froze, not going black but no more doing
updates e.g. no mouse moves are seen, no video update, nothing
- The system otherwise was happy and responsive I could continue to work on
the other screens
- The content stayed frozen even when e.g. changing workspaces
- I had a look, but nothing interesting came up to my non-GUI-trained eyes
- I've set up my system to power down screens on lock, so I thought maybe
lock/unlock would re-set the screen. But what happened was that all screens
successfully powered down - yet nothing ever woke up again
The messages (interesting to me) that I spot around there are:
Sep 24 17:31:34 Keschdeichel xdg-desktop-por[952454]: Failed to associate
portal window with parent window
...
Sep 24 17:33:52 Keschdeichel gnome-shell[5030]: Can't update stage views
actor Window drag helper [ClutterActor] is on because it needs an allocation.
Sep 24 17:34:02 Keschdeichel gnome-shell[5030]: Can't update stage views
actor unnamed [Gjs_ui_altTab_WindowSwitcherPopup] is on because it needs an
allocation.
#2 second time
1. Oct ~18:00 +- 25 min (The meeting was important and hence I failed to spot
the exact time)
- I was in a screen sharing session (coincidence or am I just having too many
meetings?)
- Then suddenly I found the same screen (4) frozen
- My counterpart told me they could still see me move and even the active
sharing of screen 5 still was updating
- I was again looking into the logs, but again found nothing obvious to me
- I reached out to #desktop what I should look out for but didn't catch the
reply before auto-screen save kicked in. That in turn again made the system
fully unresponsive so I had to reboot.
Again I found the same messages,
Okt 01 17:46:02 Keschdeichel xdg-desktop-por[6150]: Failed to associate
portal window with parent window
Okt 01 17:46:04 Keschdeichel wireplumber[4976]:
<WpPortalPermissionStorePlugin:0x5814964a3840> Failed to call Lookup:
GDBus.Error:org.freedesktop.portal.Error.NotFound: No entry for camera
But in hindsight I consider these red herring, as I see them more often.
$ journalctl -b -1 | grep "associate portal window with parent window" -c
14
I asked in Desktop what to look out for and got the good hint to look for
"drm" ot "atomic".
I found this one:
Sep 24 15:49:28 Keschdeichel kernel: i915 0000:00:02.0: [drm] *ERROR* Atomic
update failure on pipe B (start=338711 end=338712) time 137 us, min 1073, max
1079, scanline start 1072, end 1081
But that is only in one of the logs and hours before the issue happened
the second time.
- I'll attach the full journals of those two cases and run apport-bug to
- collect the usual-suspect information. I hope that this makes this good
- enough to be somewhat helpful, if you end up having some theories let me
- know what I should check next time as I keep control of the other
- screens that should be well debuggable if only I'd know what to look
- for.
