[Bug 564463] Re: x61: Clonemode active while in docking station with closed lid

[Kamal Mostafa]

Following up on the suggestion by Steve and email with Torsten, lets see
if we can make an xrandr-based solution work.

Using a rather different laptop (old Thinkpad T20 with S3 graphics) I
find that if I have the external VGA output connected to a monitor while
I'm booting up, then the LCD stays dark and the gdm GUI login screen
comes up in a higher resolution (on the monitor) than is supported by
the laptop LCD -- so in my case, it is not coming up in clone mode.
However...

I can force the gdm login screen (and subsequent user X session) to come
up in whatever resolution I wish by inserting an xrandr command near the
top of /etc/gdm/Init/Default .  I think that an xrandr line as shown
here would be appropriate for the X61 based on your xrandr.out:

/etc/gdm/Init/Default
    ...
    xrandr --output VGA1 --mode 1280x1024    # <--- try inserting this before the /sbin/initctl line
    /sbin/initctl -q emit login-session-start DISPLAY_MANAGER=gdm
    ...

Hans-Gerd, please try that and let us know whether it works on the X61
to overcome the clone mode problem.

Also, this article describes additional resolution setting methods that
may be relevant: https://wiki.ubuntu.com/X/Config/Resolution
