I need this because my dell notebook video card is only not freezing if I use nomodeset on grub.
But then, I am limited to 4:3 resolutions (right?).
So, I am looking for a way to not stretch the screen image (1024x768) on the full resolution (1920x1080) monitor.
I wanted to let the 1024x768 (or 1440x1080) be in the middle of the screen (with a black margin on each side), not stretching!
I cant find a way to command xrandr to do that, I tried many things on the --output and --pos but nothing help to accomplish that.
Even better would be if there was some way to tell VESA to use 1920x1080 directly tho.
