Ubuntu 22.04.1 Every so often all screen icons disappear then reappear. It occurs within ~2 seconds and has been happening for a few days only. Very annoying. If I'm searching for a string inside editor this "bug" resets the search and I end up typing elsewhere. At a guess a "trap" that DMESG reports seems to coincide with the "bug" occurrence.

traps: gjs[78084] trap int3 ip:7fcf23e98ccf sp:7fffae490260 error:0 in libglib-2.0.so.0.7200.1[7fcf23e59000+8f000]

Any ideas?

  • Thanks to Artur for correcting my English/Spanish overlapping spelling of "ocurrencia" and painting some nice colours. Do tell, as I am new to this forum, why the colours? – Atalaya Dec 07 '22 at 06:59

I had this problem when I attempted to update from 21.04 directly to 22.04. Did you recently upgrade from 21.04 to 22.04? Apparently there is no upgrade path from there to 22.04.

I wrote it up and someone answered me here.

It could also be your windowing system...

Which windowing system are you running?

  1. Wayland
  2. X11 / Xorg

I had numerous problems while running Wayland, all of which were resolved when I switched to Wayland.

Check which one you're running in System Settings...About...

Mine shown here shows I'm running X11, but yours may say Wayland.

system settings

It's likely that if you are running Wayland, that a change to X11 will fix the issue. Good luck.

    Morning, changing to X11 DIDNT change the behaviour. I'm back to Wayland. The traps are still occurring and coincide with the disapearring desktop icons. l – Atalaya Nov 30 '22 at 08:46
