OK, I'm totally sure it's a freeze.
Moreover, gnome-shell stack trace looks normal, event loop runs just fine.
I can generate and provide core file if needed.
What I managed to debug so far, is that in case of multiple /dev/dri/cardX
being created
frame_cb in meta-stage-x11.c:296 is not called

Bugs,
Thanks.
BTW, is there any help we can provide ensure the fix makes its way to
the official 20.04 LTS release (I guess it might be tough I guess, due
to release candidate being out today, am I right?), or at least one of
the early updates?

Public bug reported:
Discovered when testing EVDI-backed screen
(https://github.com/DisplayLink/evdi).
While adding new device /dev/dri/cardX xorg locks, it can be observed by the
cursors that stop blinking or menus not responding. Sometimes it is just a
short (1-2 sec.) pause, but sometimes
Point is, there is no crash file. Graphical environment is not responsive, but
nothing seems to have crashed.
If there's a stacktrace or core file needed, no problem, I can rebuild in debug
mode, attach debugger and gather those.

Title:
mokutil ignores timeout parameter
To manage
Ok, I have analyzed mokutil's src code and from what I understood,
timeout has to be a single parameter. Of course, it can be changed
there, but calling it several times in a row should do not harm either.
Splitting its invocation in two seems to fix the problem; the bug can be
reassigned to
Consulted the bug on #gnome-shell IRC.
Next step is to track down the event that actually triggers execution of
cogl_glib_source_dispatch. It's possible it simply does not arrive. BTW, this
does not rule out Xorg as potential culprit, it might be simply not delivering
the expected event. This
Tested on Dell XPS13 (Intel GPU) and Precision M3800 (Intel/Nvidia-nouveau),
with evdi-backed displays mostly focusing on enabling/disabling screens, both
by system settings as well as ACPI events (lid closing/opening).
Looks fine so far.

A recording would preferably be better, a screenshot might not give the
full picture. Anyway, sure, I shall post it. The case I'm describing is
more extreme, the squares are way bigger and flickering constantly, most
of the time effectively preventing usage of the machine, such messy it
gets.
Adding movie depicting the problem. And it happens without actually
moving the mouse, after dragging the window.

Fair point, but question is if it's software cursor from Xserver's
perspective. NVidia driver might be blending the cursor in, while
"emulating HW cursor" on the Xorg's end, right?

@vanvugt is there any chance this gets merged? Preferably on Xorg's end,
if you can give me a hint on whom to tag there it would be most
appreciated.

Public bug reported:
The issue has initially been discovered for resolution 1366x768 on a
DisplayLink (evdi)-backed device, but applies also to UDL, as well as
reverse prime setups (rendering on Intel, output through NVidia).
The issue manifests with 1366x768 and several other resolutions only,
Just reproduced on 20.04.
xserver-xorg-core:
Installed: 2:1.20.8-2ubuntu2.2
Candidate: 2:1.20.8-2ubuntu2.2
No reproduction on 20.10 build, but it was tested on a different machine
and issue might be hw-dependent. Te be confirmed on the same computer
soon.

Managed to reproduce on fresh download 20.10, too. OTOH, I remember
seeing that gone in some cases on 20.04. I wonder what the exact cases
are, as apparently this seems more complicated than "reproduces always".

Same when using DisplayLink adapter via both EVDI or UDL. Crashes most

Looks like with ath10k_pci FW ver. WLAN.RM.4.4.1-00157-QCARMSWPZ-1 the
issue is gone or at least delayed that much, that it makes it
irreproducible for me.
The faulty one wasWLAN.RM.4.4.1-00140-QCARMSWPZ-1.

I cannot pinpoint the exact scenario, but it happens most often when trying to
build Xorg-master from source via their build.sh script.
Setup: WiFi connected, xorg is built in terminal window. Speculatively I would
say it say realted to
It *seems* better in the sense that the problem appears later, say after
20 minutes of operation instead of 5. Nevertheless, it's not fixed.
