Thread: Lenovo T61, no display on external screen, when docked

-

hi,
installed ubuntu 11.10 on lenovo t61 , went fine, during install.

when dock machine , turn on, external monitor (dell 2001fp) turn on , see console+ initial ubuntu boot. when ubuntu opens login manager, monitor turns black , says no screen input. if open laptop lid, see login manager on internal display.

can see, proprietary nvidia driver (quatro 140) detect dell monitor on dfp-1 , internal lcd on dfp-0, in have screen-0 device listed in nvidia graphics manager.

xrandr reports 1 display (the internal lcd).

fun tried uninstall nvidia driver , replace mesa one. checked glxinfo verify driver replaced.

using mesa driver work both docked , undocked, hardware acceleration missing, unity becomes sluggish everyday use.

want nvdia driver behave, properly, right i'm out of ideas

hi
did find solution problem? have exact same issue
cheers
yannick
