Region Monitor Limit on Linux

I have a laptop with a broken 13 inch display. The left half of the display is completely black, and I still can not fix it. I was wondering if it is possible to write a program in any language to limit the display to the right, this means:

  • Changing the resolution to half width currently has either

  • Keep proportions, but reduce the display and send them to the right.

I prefer to use a method that can be used on Linux (Windows will have second priority)

Language is not a problem (although I assume C ++ is the way to go), and I'm looking for some tips.

Thanks in advance.

You can change the resolution using xrandr Linux.

maybe (if xrandr does not make you happy), you can use Xnest , position the Xnest root window correctly, and run all other X11 applications inside Xnest .
