Thread: Unity only works with dual screen (not on laptop standalone)

hi

have lenovo g550 geforce g210m graphics processor.

use twinview when plug in 23" samsung monitor (1920x1080) laptop , works fine unity. have laptop (1366x768) configured primary display.

if start laptop in unity resolution wrong (it seems using 1920x1080 display). if start laptop in "ubuntu classic" displays fine.

when upgraded 11.04 in twinview mode. not sure if significant.

here display part of xorg.conf file
