I hooked up a tv to my linux computer. I noticed the screen was offset by about 200px to the right, leaving behind a black vertical strip on the left of the screen and cutting off a portion of the right of hte screen.
So I executed the command sudo xrandr --output VGA1 --pos -200x0
but all that did was blink the tv for a split second without changing anything.
I tried repeating the xrandr with the --pos option on another computer. I noticed that the screen reposition as expected for just a fraction of a second before returning to it's original position.
How do I get xrandr to re-position screens ? What's wrong with my commands?
