Bug Description

Binary package hint: kdebase-workspace

Using HP nc6400 laptop plugged into 2 HP LP2065 monitors. I am unable to place monitors side by side. Mirroring monitors as well as positioning one monitor above or below the other works fine. I have been able to reproduce this on both Kubuntu 10.10 rc as well as ubuntu 10.10rc. Atempts to place monitors left of or right of results in a blank screen.

Hi Jesse,
   What graphics hardware is your laptop running with? There is a bug 619663 that affects dual monitors on Intel graphics hardware, but looking up your HP nc6400 it looks like some have Radeons and some are Intel.

Can you add a /var/log/Xorg.0.log from a run when you are trying to put both monitors next to each other.

Hi Dave,

Sorry I missed the other bug. This laptop also has an intel card.

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)

the Xorg.0.log file after making the switch is below.
