So I recently installed ubuntu mate 20.04 after a trial of leenux with the fast lightdm desktop for this old ASUS 1001P clamshell with a 7" screen
all was well until i ran sudo apt update an then sudo apt upgrade.
after it finished I shutdown. when I fired it backup about 4 days later my green mate desktop env was gone with having to click activities or use super key to pull open my favorites menu including my application menu. I have no idea where to start to revert it to what it was.
this new env which says its still lightdm has made the gui on this old clamshell "windows" like again, slow and sluggish. and it has removed full text from application menu icons.
[email protected]:~$ grep '/usr/s?bin' /etc/systemd/system/display-manager.service
It looks like a compact version of a full ubuntu which I have on 3 other laptops and a PC as well, but even their side bar/favorites bar remains viewable.
I have a couple screen grabs of it as well, any tips are ver appreciative, mate-tweak has also disappeared.
