I am on Ubuntu 20.04 desktop.
1.) No extensions will launch, even though
https://extensions.gnome.org/local/ says they are installed and activated.
2.) Gnome-shell ignores appearance settings in the upper-right settings menu (power, lock, etc.). For example. I put the launcher on the bottom of the screen in settings... nothing happens, launcher remains in default left hand positions
3.) Certain application will not launch Chromium, Opera, etc.
a.) I had Stacer install installed. I uninstalled Stacer and my entire system froze.
b.) I used
ctl+fn+alt+f5 to bring up a shell and used
killall -9 gnome-shell && /usr/bin/gnome-shell seeking to restart my desktop. Desktop restarted but all gnome-extensions were missing.
c.) I decided to use
Timeshift to get myself out of the hellish ubuntu rabbit-hole that I have crawled into. I restored to the state/ condition of the previous night. Although Stacer was back... All gnome-extensions were still gone.
d.) From here, I completely uninstalled and then reinstalled gnome-shell. I re-installed the gnome-shell native connector. same problems above
e.) I have apparmor installed. So I completely disabled it and rebooted. Chromium & Opea came back, but other problems above remain
I decide to try
Timeshift again, since at least my launcher appear on bottom as normal.
1.) After timeshifting I disabled apparmor and rebooted. It appears that my apps not launching are due to apparmor vs. snap issues that somehow got amplified when I reinstalled gnome. I can troubleshoot apparmor later.
2.) I created a new system administrator user on @vanadium's advice below. Indeed, the new system administrator has the ability to install and run gnome-shell extensions, without problems.
anyone have any ideas on how to get my desktop working again?
