i tried to get kde plasma on my fedora, when i booted it up there was just a black screen. i couldn't type any commands either, it was toast
thankfully i've got windows dual booted because i'm a filthy 
who uses it for vr games. unfortunately windows doesn't let me see my linux drive's files so all of my personal files are unrecoverable.
thankfully i think the most i had on my computer was my music (yt-dlp is so easy i can get it all back in 30 minutes tops) and a few files from some project i was working on, sucks but not worth spending hours troubleshooting. oh well.
on the bright side, i'm RETVRN-ing to my old reliable, linux mint with xfce. i'll miss hot corner and the other niceties that gnome has but xfce will be a bit more comfortable for me.
imo the best feeling is finding out the root cause and unfucking the system when it's like this
