@iBrokeMyLinux Where did you make the change?
- In displays or in a config file???
So... With the screen all twisted (is what I'm assuming)...
Log in to the desktop... Give a sec to load...
Launch terminal with the keys:
CTRL ALT T
You will be within terminal - don't click around...
type...
xrandr -s 800x600
Your resolution should change to a 800x600 screen...
You can now launch DISPLAY (type from menu) to change resolutions..
This is a bit convoluted - but it may be the simplest...
