Login loop after setting to unsopported resolution with randr -s

  • 772

This is my first day with Ubuntu 20.04. I was researching in google for a feature like AMD virtual resolution and came with randr and tested it.

I set it to unsupported resolution, and I got "input is not supported". I tried using google chrome remote but no luck. I restarted after that and that's where the login loop began for me.

I uninstalled gdm3 and installed lightdm and not it wont even boot to os. i do plan on reinstalling but just in case on future this happened again what fixes can i do?

display-resolution randr
