Title:
gnome-shell crashed with signal 5
Status in gnome-shell package in Ubuntu:
New
Bug description:
Probably also affects ubuntu dock...
... because this signal 5 error happened right after I tried to turn
off ubuntu dock (after which I would have turned on dash to dock
(installed from repo) to configure some custom settings, and then
switch back to ubuntu-dock). Ubuntu dock itself did not turn off, but
this bug report got launched almost immediately.
Earlier I had already observed that I could not switch off ubuntu
dock, but I didn't see this signal 5 error. Since then I just ran
today's updates, but I didn't see that either gnome-shell or gnome-
shell-extension-ubuntu-dock received an update. For that reason I'm
not certain the signal 5 error is directly related to my problem or if
it happened separately and the bug report happened to come up at the
right time to appear causal.
Using the gnome extensions website (via firefox) to do all this. The
toggle switch on ubuntu dock appears to work, but ubuntu dock itself
does not switch off.
This used to work, until fairly recently. I have a laptop also running
18.04 where I've already successfully done what I was attempting to do
here today.
NB: The extensions tab on gnome-tweak also doesn't work. The toggle at
the top is on and it lists all the extensions, but only shows them all
off. But I imagine that should be a separate bug report.
NB: Turning on dash to dock after turning off ubuntu dock (but seeing
that it didn't actually disappear) causes the shell to crash
completely and exit; subsequently unable to log in until I ssh in from
another machine and dconf reset -f /org/gnome/
(I'm getting used to having mostly default settings these days!)
BTW the only changes I wanted to make to the ubuntu dock settings
were:
1. to make its background exactly match that of the top bar in
Ambiance, when touched and not touched by other windows
2. to be able to click on launchers for running apps to minimise them.
I'd be happy with those being in the new Dock settings panel alongside
auto-hide, icon size and position on screen. Or at least the second
one (click action) and the first just being how it is by default! :-)
