How to set a different screen resolution?

Question

linux

I connected an external VGA monitor to the laptop, the monitor supports 1360x768 and in the settings a maximum of 1024x768. Under Windows it can be at 1360x768. The laptop monitor is disabled and the output should be VGA.
And when editing Xorg.config with the Invidia panel, after switching graphics, nothing took off, what to do?

Answer 1

Something like this:

xrandr --output VGA1 --mode 1360x768 --pos 0x0  --output LVDS1 --off

Answer 2

Use XRandR
Or try:
sudo gedit /etc/usplash.con
There change to:
# Usplash configuration file
xres=1360
yres=768
don't forget to reboot
