I've been reading this old article about changing the resolution of a device through .xprofile: https://wiki.ubuntu.com/X/Config/Resolution#By_Session_with_.xprofile
I've added the line: xrandr --output DP-1 --mode 800×600 --rate 60 That resolution is supported since I can type this manually and change the resolution during a session. I've even tried without "rate" and with "DP1" instead.
My problem now when I add that line in .xprofile is when I reboot, I have to type a Username and password which I normally never have done before and haven't setup.
The only way for me to fix this now is to press G at startup to restore everything to default.

What have I done wrong?
