Are the other laptops all using openchrome ? Did this setup work with any of the other laptops ? Does this setup works with a standard length VGA cable ? Also, the resolution looks weird. Are you sure the native resolution of your external screen is 1366x768 ? It looks like a laptop's screen resolution.

Something like that : $ xrandr --addmode VGA1 1366x768 xrandr --output VGA1 --mode 1366x768 Possibly you might also need to add a modeline before doing the above : $ gtf 1366 768 60 # 1368x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 85.86 MHz Modeline "1368x768_60.00" 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync $ xrandr --newmode 1366x768 85.86 1368 1440 1584 1800 768 769 772 795 -HSync +Vsync Never tried that myself, so your mileage may vary...
