Hi all,

I have been playing with xrandr to get multi monitor support working on
my intel i915 mobile card. I running unstable.

It works ok, except the primary monitor gets set to the external vga
screen!

How can I get the primary display to be the laptop panel and the
secondary display to be the external vga screen?

The current default behaviour seems really stupid and I can't believe
that there isn't a way to do it, though google has only turned up people
with the same problem and no one with a solution.

cheers

Do you mean this?

# This is for getting the video on the LCD
xvattr -a XV_PIPE -v 1

I have this in my .icewm/startup. If you don't use IceWM you have to put
it somewhere else where it's executed after start of X.

The default behaviour is not so stupid if you consider many people would
need this for an external projector, TV-out, whatever.

Ahhh. So it is related to xv maybe. I'll give it a whirl. Don't have a
second screen at the moment.

Maybe, but it would be better to get accelrated video on both outputs.
Windows manages to do this somehow (although you tend not to be able to
drag a video between windows once it's started.)

The hassle is with different sizes of screens. Sure, you can drag the
gnome panel around so it's where you want, but if you're projecting on to
a narrower resolution than the laptop panel, the location of launchers
and other stuff in the panel gets screwed up when it gets shifted to the
external screen. Plus, during presentations, I'd rather be certain that
the primary display where random windows might appear was not the one
being projected to everyone...

Thanks for your .

I'm not sure if this is your problem, but my panel was working fine, but
I couldn't see any videos (blue screen). This is how I found that
solution.

Yeah. It didn't work. But your comment is useful to know. Hopefully the
driver and xrandr will continue to improve.
