Due to a fault with my screen (white vertical bar, the rest is fine), I would like to be able to tell Linux (X and console) to only use part of the screen.Does anyone know if I can achieve this with kernel boot params, under-scanning, xrandr, or clever X configuration (or a combination thereof).I want to configure it to use something like 800px x 1080px (it's a 1920x800 display, the white bar appears to the right hand side), but without trying to centre the image (as adjusting the screen resolution does).All ideas welcomed.TIA.
Use partial screen display
linux;kernel;x11;xrandr;display
