can't think how to ask this question, so apologise for the super long question.

I have a very low power machine, with a very tiny screen. The problem is the screen size, the computer is more than fine for the tasks.

I have been able to increase the resolution of the screen by overdriving it. I loose quality of image but that is ok. What I would like to do next is make the desktop larger. 1920x1080 sounds good, but I don't want to change the monitor from 1026x614. What I would prefer is the viewed area of my desktop to follow the mouse around. Does that make sense? If it does and you know what I am trying to do, even giving it a name so I can search how to do it on google helps. The OS I am using is Raspbian on a Raspberry pi 3

Regards Monery

You should be able to set up a panning viewport with xrandr. E.g

$ xrandr --output eDP-1 --mode 1026x614 --panning 1920x1080

and be sure to replace eDP-1 with whatever your monitor is called, and 1026x614 with whatever your display mode is called. A plain xrandr without arguments should tell you that. Try also

$ man xrandr

for more details.

  • using this command generated the following error xrandr --output default --mode 800x480 --panning 1920x1080 xrandr: Failed to get size of gamma for output default xrandr: screen cannot be larger than 800x480 (desired size 1920x1080) – Monery Mar 31 '18 at 20:50
  • The man page suggests adding --fb 1920x1080 as first argument. Did you try that already? – Ralph Rönnquist Mar 31 '18 at 23:19
