Booted up my one laptop running #Linux Mint after about a week of not touching it... to my surprise, it booted into GNOME when I have Cinnamon installed. No reason, just randomly did it.
Not only this, but the installation of GNOME appears to be borked, with light-and-dark options doing absolutely nothing, certain theme options from the Cinnamon installation are still present but completely unchangeable, my wallpapers (including the login screen one) were all reset, tap-to-click being disabled and so forth.
I haven't installed anything new, I haven't done anything unusual in system settings, it just decided it wanted to casually boot into an entirely different desktop environment.
I tried searching for anyone else having this issue but couldn't find anything. It looks like I might just have to spin up Timeshift and run it back a bit to see if that fixes the issue.
Bizarre. Absolutely bizarre. 🤷♂️
