I'm trying to debug a Gnome Shell extension called multi-monitor addon. I'm running PopOS. I was using the multi-monitor addon just fine for quite some time, and yesterday I rebooted and the extension became disabled.
When I open the Gnome Extensions in the browser (https://extensions.gnome.org/extension/921/multi-monitors-add-on/) it shows as disabled. When I enable it nothing happens and when I refresh the page it remains disabled.
I tried following this stack exchange article to get logs using
journalctl, but I didn't see any logs that were more recent than 3 weeks old.
I really don't know what I'm doing with Gnome shell extensions, they're totally new to me (I am new to PopOS and more familiar with Linux Mint which never used Gnome Shell extensions).
I could use some direction on how to go about tracking down an error message that will help me understand what's broken.
I've noticed in
journalctl logs the following error repeating itself:
Dec 17 10:31:49 popsicle gnome-shell: JS ERROR: TypeError: null has no properties _onFocusChanged@resource:///org/gnome/shell/ui/closeDialog.js:135:9 reset@resource:///org/gnome/shell/ui/viewSelector.js:452:26 vfunc_hide@resource:///org/gnome/shell/ui/viewSelector.js:303:14 _hideDone@resource:///org/gnome/shell/ui/overview.js:667:27 onComplete@resource:///org/gnome/shell/ui/overview.js:653:36 _makeEaseCallback/<@resource:///org/gnome/shell/ui/environment.js:84:13 _easeActor/<@resource:///org/gnome/shell/ui/environment.js:165:64
In the Extensions UI control panel I see the Multi Monitor Add-On, but I cannot enable it. It simply ignores attempts to click on the enable/disable slider. This is the same behavior I get in the Gnome Extensions Firefox addon website when I try to enable it there as well. I've also removed it and added the extension again with no change in behavior.
