The Laptop screen has a hardware resolution of 1366x768, the external monitor a hardware resolution of 1280x1024. If I set up the second monitor using xrandr --output VGA-0 --mode 1280x1024 --pos 1368x0 --rotate normal --output LVDS --mode 1366x768 --pos 0x0 --rotate normal (or the gnome gui, the effects are equal) I expect: 1) the left 1366x768 area to be on the laptop screen, and 2) the right 1280x1024 area to be on the big monitor. But I observe: 1) happens as expected 2) happens almost. Instead, the 2 rightmost pixels on the laptop monitor are repeated on the left border of the big monitor and the two rightmost columns of the right monitor are not visible on any monitor at all. If I switch the laptop monitor resolution to 1280x720 (or any more "common" resolution), this effect does not occur and everything works as expected.

I assume the first '--pos 1368x0' is a typo and should be '--pos 1366x0'. I'm afraid this is not easily fixable, as the hardware only supports horizontal offsets which are a multiple of 4, so the drivers just round down values that aren't.

(Please excuse my ignorance if this is a stupid > question :-) Vertical alignments have to a multiple of 2 as well. It applies to most Radeon asics. Not sure about other vendors, but it's likely they may have similar requirements.

See comment 1. 1366 is not a mutliple of 4 while 1920 is. IIRC, vesa mandates the the hdisplay value be a multiple of 8, so 1366 is technically not vesa compliant.

It messed it all up, as you can see in the attached picture. The patch was applied on 3.13rc3 on a Ubuntu saucy 64bit. The configuration included a common bottomline of each display. The 1366 monitor was the left one (notebook). A configuration with only one display worked, so the patch didn't effect that.

What happens is that something doesn't expect offsets that aren't multiples of 8. When you have the 1920-1366 you end up with the 1920 starting at X=0, and the 1366 starting at X=1920 (which is divisible by 8) - so everything is happy. When you have the 1366-1920 setup you end up with the 1366 starting at X=0, and the 1920 starting at X=1366 and having a display not aligned to /8 value gets the thing confused.
