Xrandr –pos doesn’t do anything

xrandr

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?

I had a similar problem and found this thread: How do I align the bottom edges of two monitors with xrandr?. BatchyX's answer helped me a lot.

Xrandr doesn’t detect monitor on hdmi port

I figured it out; my generated xorg.conf had the wrong nvidia module path and didn't specify the busid. To find out the busid I used:

$ lspci -v

01:00.0 VGA compatible controller: nVidia Corporation GT200 [GeForce GTX 260] (rev a1)

Then I edited xorg.conf so that it had a section similar to this:

Section "Device"
    Identifier "Device0"
    Driver "nvidia"
    VendorName "NVIDIA Corporation"
    BusID "PCI:01:00:0"
    Option "NoLogo" "true"
    Option "UseEDID" "true"
    Option "ConnectedMonitor" "DFP"
EndSection

Section "Files"
    ModulePath      "/usr/lib/<path to nvidia driver>"
    ModulePath      "/usr/lib/xorg/modules"
EndSection
