Public bug reported:
Desktop hangs frequently, sometimes more than once per day and can result in
loss of work.
Today I found a way to easily reproduce.
- sudo apt-get install key-mon
- start new session with nothing but gnome-terminal running. Unnecssary to
reproduce, you can have dozens of programs running.
- key-mon &
- right click on key-mon window and open settings
- enable meta key (may not be necessary)
- switch to misc tab
- Check window decoration with nothing else checked
- attempt to uncheck window decoration. Fails. Trying multiple times won't
help and may make things worse.
- Desktop is now frozen and will remain this way for an indeterminate time but
may eventually come back within a minute. If you actually had stuff running
on your machine, chances of coming back aren't great. Symptoms include:
- psensor graph continues to update
- cannot make terminal respond.
- cannot drag windows
- cannot focus windows
When it came back, one of 3 gnome shell processes previously detected
using psgrep was missing and has been replaced. This is consistent with
the screen being redrawn when it comes back.
When desktop didn't come back recently, I was able to CTRL-ALT-F3 to a console
and kill okular, freecad, gimp, key-mon, firefox, freecad-daily,openscad,
file-roller, psensor, and gnome-terminal, in that order, until there was
nothing left and still did not regain control of system. Ctrl-Alt-Del ESC
also failed (though I think I did end up causing system to reboot). System
pressure after killing okular and freecad was:
===memory
some avg10=0.00 avg60=0.00 avg300=0.00 total=0
full avg10=0.00 avg60=0.00 avg300=0.00 total=0

some avg10=0.01 avg60=0.02 avg300=0.00 total=9348303

full avg10=17.43 avg60=28.42 avg300=32.91 total=795530186
I was able to reproduce this many times by turning window decorations on
and off in key-mon.
In the past, desktop freezes were frequently caused by dialog boxes
popping up including the wait of force quit dialog. I installed the
extension to disable wait-or-force quit. System still becomes severely
non-responsive when programs like firefox eat up a lot of RAM and I have
to use onetab firefox extension regularly.
