Changing the volume (with the mouse wheel over icon) locks up gnome-shell

[Peter Rhone]

If I change the volume, the display freezes right after the volume display floating indictor appears in the middle of the screen. I have to either reboot or switch to virtual terminal and killall -3 gnome-shell to restart the session.

Please, can you attach the journal for gnome-shell?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Peter Rhone (prhone-gmail)]

@3v1n0 Where can I find the journal for gnome-shell?

[Daniel van Vugt (vanvugt)]

I suggest using bug 1817335 instead, out of respect for the person who reported it first.

[SamuelB. (bw-sammy)]

I'm fine with 1817546 ;)

[Sebastien Bacher (seb128)]

Let's tag that one as blocking the update, it's making easy to lock your session without obvious way out

Fix proposed upstream: https://gitlab.gnome.org/GNOME/mutter/merge_requests/474

[Emanuele (emanuc)]

I have the problem on Ubuntu 19.04, I attach the logs, I hope they are useful.

[Andrea Azzarone (azzar1)]

Hey Emanuele,

We already know why the problem happens. A fix is ready and should be
available in the next few days :)

[Iain Lane (laney)]

This should be fixed in 3.31.92-1~fakesync, so dropping the block.

[Peter Rhone (prhone-gmail)]

Seems to be fixed with mutter 3.31.92-1~fakesync

Thanks for fixing this so quickly.

[Launchpad Janitor (janitor)]

This bug was fixed in the package mutter - 3.31.92-1~fakesync

---------------
mutter (3.31.92-1~fakesync) experimental; urgency=medium

  * New upstream release
    + Add back support for system-wide monitor configurations
    + Add cursor-mode support to window screencasting
    + Add flag parameter to grab accelerator API
    + Add fractional scaling support
    + Consider remapped keys when guessing keycode from keysym
    + Don't disable page flips after temporary failues
    + Fix crash when using "restore shortcuts" without focus window
    + Fix flicker of apps that use multiple SHM buffers
    + Fix infinite loop in EDID matching
    + Improve redraw performance
    + Reuse old CRTC if possible to avoid flicker on hotplug
    + Stop turning on-screen-keyboard off on focus changes
    + wayland: Don't maximize windows if minimum size is too big
    + wayland: Don't resetin text-input state prematurely
  * Drop old cherry-picks which are upstream, refresh other patches.
    Dropped:
      debian/patches/Update-Basque-translation.patch
      debian/patches/Update-French-translation.patch
  * d/p/sound-player-Don-t-deadlock-in-finish_cb.patch: Cherry-pick.
    This fixes a deadlock bug when scrolling over the volume indicator. (LP:
    #1817546)
  * debian/control: Breaks gnome-settings-daemon << 3.31.91. Altering the
    GrabAccelerator API will break key grabbing under g-s-d versions which
    don't use the new parameter.
  * debian/libmutter-4-0.symbols: Update. Upstream dropped a load of
    deprecated functions. This obviously is an ABI break, but we don't
    consider the ABI stable until the final release. Also some additions.
