My old laptop display is starting to break, and I have many dead pixels and other physical issues on the left side of the screen only. Of course I should get a new monitor (or ideally a new laptop), but as a workaround I'd like to configure the display to show a smaller screen size with a blank margin on the left where the broken area is.
It should look approximately like this:
+---+-----------------+-- | b | | | l | remaining | 6 | a | screen | 0 | n | area | 0 | k | (904x600) | +---+-----------------+-- |120| - 904 - | | - 1024 - |
I've managed to use
cvt to generate a 904×600 modeline, and I can add that mode to the display using
xrandr, but I cannot for the life of me figure out how to position the smaller screen on the right side of my full display. It seems like the
--pos flag should work for this, but
xrandr --output LVDS1 --mode 904x600_60.00 --pos 120x0 isn't working (the screen shows up centered in the display, with equal margins on left and right).
Any tips on how to get this to work? I'm using Ubuntu 13.10, in case it makes a difference. Thanks for any advice!
