I messed up my graphics driver by using the one from the nvidia site, then using their uninstall script to try to revert to the distro-installed drivers. Now, when I try to boot the machine, I get a black screen with no apparent way to interact with it. No grub menu is visible - I’ve tried holding shift and pressing esc repeatedly. Shift does nothing, and spamming esc prints a single “^[” to the terminal but does nothing after that. Ctrl+Alt+F2/3 also does nothing. Is there anything I can do to reset the settings by booting from a live USB? The distro is KDE Neon.
