Well I changed my nvidia settings from on demand to a lower value and rebooted Mint a few weeks ago. Then there was no display at all and several hours/days of searching led me to reinstall Linux again and I did not have good backups. There was probably an answer there, but my frustration with Linux is real!!! I still refuse to use anything else and flop between manjaro and mint. I think having proper system backups and a live USB ready to go is helpful…I’m much more defensive running Linux because I keep getting shitty surprises, but I still feel better about it over using windows.
