Comment 2 for bug 183873

Log file from running X on the N610c

I have a Compaq Evo Notebook N610c hooked up to a docking station that I'd like to use dual-head on, but I'm only able to do dual-head in a clone mode since xrandr commands aren't working.

I've tried using xrandr to disable one of the monitors and then reenable it at the new location with these commands:

xrandr --output DVI-0 --off
xrandr --output DVI-0 --right-of VGA-0 --mode 1280x1024

However, xrandr doesn't seem to do anything except display this error when I run it (even with -q):

xrandr: Output LVDS is not disconnected but has no modes

Here's what my xorg.conf file looks like:

I've tried adding 'Option "Ignore" "True"' to the Built-in display monitor section, but then X refuses to start at all.

Let me know if there's anything else you want to know about this system.
