Mouse stuck on 2nd Screen (KDE 4.1. Nvidia Xinerama)

English Applications
#1

So, basically I have my dual output Nvidia 7600GS gfx card hooked up to
two LCD monitors. I wanted to have two linked desktops, where I could
send some windows to the other monitor, but apparently Xinerama is as
close as you can get…anyways…

my computer:

Nvida 7600GS using the Nvidia binary driver (current)
Opensuse 11.0 with all updates installed
KDE 4.1.3 the most current version

So it took me a while but i got Xinerama kinda working.

Only problem is either I cannot get my mouse on to the other monitor at
all, or if I do I cannot move it back.

If I use this line in my xorg.conf I cannot move it on to the second
screen

Code:

Screen 1 “Screen1” LeftOf “Screen0”

If I use this line when I move it on to the second screen it gets
“stuck” on that screen

Code:

Screen 1 “Screen1” RightOf “Screen0”

The only other thing I can think that might be related to this is that
SOMETIMES when I start up my mouse will not work, and the only way to
fix this is to reboot.

Because I know the secret is here somewhere…

I have basically the same setup but with the 7600GT instead of GS. I
set up mine using the nvidia-settings program and setting up twinview in
the “X Server Display Configuration” tab.

In case it helps, here is my xorg.conf that is working. Comparing
them, it seems like you should have the xinerama turned off and instead
use the Nvidia twinview, but I’m just guessing.

First. Thank you for your reply.

I had Twinview set up, but it doesnt accomplish exactly what I want.
The major difference is with Xinerama the system KNOWS you have two
monitors. With Twinview it just thinks its one big monitor…so when
you maximize something…it looks like crap.

Neways, some further details…

i dont think this problem is kde 4.1.3 related. I installed gnome to
see if it would work, and i also tried icewm and such.

I read somewhere on the net that kdm starts up and ‘controls’ the
monitors before logon…can anyone confirm this and if so how can i try
gdm or xdm.

thanks for any help

Well, I am not an expert in configuring X, but my setup does work the
way you are asking for. When I maximize a program, it only fills one
screen and I can drag windows from one screen to the other. I am also
running KDE 4.1.3.

I am attaching an image of my desktop and the nvidia-setting program
with the settings I am using. Note that when I maximize the window, it
does only fill the one monitor.

[image: http://www.physics.oregonstate.edu/~elserj/snapshot1.png]

I’m sure it is a setting somewhere in xorg.conf, but I couldn’t tell
you for sure which one. If it were me, I would backup my xorg.conf and
then try the nvidia-settings program (as root). If it still wasn’t
right, I would then try to hand-edit xorg.conf and change the sections
that are related to the graphics sections (the serverlayout, serverflags
and screen sections).

Hope this helps.
