[mdlug] Dual-Monitor use with Jaunty

[David McMillan]

	Well, this is... odd.

	My dual-boot laptop (XP and Jaunty with Gnome) has been running quite 
nicely with a dual-monitor spread-desktop setup under XP since I bit the 
bullet and bought a nice big LCD monitor to save my eyes.  Very nice.
	But getting it to work under Jaunty has been... interesting.

	First, System>Display redirected me to the Nvidia display setup 
utility, which let me re-write my xorg.conf (after jumping through some 
hoops -- I ended up changing the permissions on xorg.conf to get access 
since I couldn't sudo the Nvidia utility).  After figuring that out, I 
set up my external monitor to one side of my laptop screen, and voila! 
It worked.  My desktop now spanned two monitors, my mouse jumped from 
screen to screen as I moved, and I could drag-drop items on my desktop 
to the other screen....

	But I can't seem to get any *apps* onto the side screen.

	One thing I've noticed that's different from XP's dual-monitor setup is 
that my desktop isn't *spread* so much as partially *duplicated.*  That 
is, the Gnome background is repeated, and the start/task bar is 
partially duplicated on the secondary screen -- the icon for 
networkmanager, for instance, is missing from the second bar.

	The screens don't seem to associate to different desktops, either.

	So, when I start an app, like a terminal, it always pops up in the main 
laptop screen.  And when I try to drag it over to the side screen, it 
"bounces" back to its original position as soon as the mouse cursor hits 
the edge of the main screen.

	One other difference:  when I move the mouse cursor from one screen to 
the other, the screen I left retains a "phantom" of the cursor where I 
left it, a little like a VNC session does sometimes.

	So, anybody else run into this?
