Ok wow thankyou RBEmerson
Interesting events transpired, magic you could say but as the naive apprentice, it didn't go as expected when i waved my wand.
so i followed instructions 1-4 to the copy and paste degree with the exception of adding the 384 and an extra l on "instal". I salute your test of awareness. All seemed to be going to plan.
I reboot the computer. i'm guessing that's what no.5 meant as copy and paste failed me.
Some kind of alice in wonderland trickery took place as the desktop font doubled in size. Very discombobulating. the screen resolution was now 640x480 instead of 1280x1024 and unchangeable. I kept cool however as the world around me was spinning into madness. I C&Pd number 6. There was one lonely nvidia driver.
Most relevantly Shotcut did not execute.
So I went through stages 1-3 again which removed nvidia-384. I figured i'd try a reboot here which to my delight restored the correct resolution along with my sanity.
Thanks for your idea my friend. It may not have resolved the shotcut problem but i had a wild adventure and i REEAAALLLLLYYY appreciate my screen resolution now! Its true what they say, we don't appreciate what we've got till its gone.
