A few days ago I upgraded my Dell XPS 15 7590 to 24.04.2 LTS. The upgrade made the screen black, but by dropping into a terminal and using my cell phone I was able to get the upgrade completed. It worked a couple days and then I “cleaned up” some things. In that process I lost the ability to use my external monitor, and also the ability to browse using chromium or firefox. Most other things work, but these two apps are the topic of this thread. Although I’m a long time uBuntu user I confess little knowledge of snaps. So here is what I’m seeing.

So did I lose all of my desktop-launch snap slots? I just don’t understand what is going on here even though I did read the intro in this forum. I’ve tried sudo apt install --reinstall ubuntu-desktop^ and that did not change anything. Is the loss of my external monitor perhaps influencing this? I uninstalled gnome-42 and that apparently caused the save shown above. How can I try undoing that? I didn’t save it explicitly.
Sorry if I’m overlooking a more helpful venue for this, but I’ve searched around and haven’t found anything helpful. Others said this is the place to get help.
