Hello, First I changed my second nVidia from 6200 to 7300 (PCI-E Slot #2) so now I have an 6800 GS on slot 1 and an 7300 GT on Slot 2. There is no SLI bridge installed. Both cards has fitted only an screen on the DVI port. The VGA is not connected. With my old lenny installation the dual screen configuration was working. I installed fresh lenny and upgraded full to testing. Because of another problem with an vmware xorg module a have removed the xserver-xorg-video-all and installed only the following driver modules:
ii xserver-xorg-video-dummy 1:0.3.3-2
X.Org X server -- dummy display driver
ii xserver-xorg-video-fbdev 1:0.4.2-2
X.Org X server -- fbdev display driver
ii xserver-xorg-video-nouveau
1:0.0.15+git20100329+7858345-4 X.Org X server -- Nouveau display driver (ex
ii xserver-xorg-video-nv 1:2.1.17-3
X.Org X server -- NV display driver
ii xserver-xorg-video-vesa 1:2.3.0-3
X.Org X server -- VESA display driver
I'm use nv module at the moment.
Without having an configuration file on first screen (Monitor on 6800 GS) all
looks
good.
If I create the dual screen configuration with Xorg --configure and test the
configuration
with Xorg -config xorg.conf.new -retro (retro so I can see output and an
pointer on
the screen) both monitors now show the classic background and the classix X
pointer on the
screen which is connected to 6800 GS card.
I can now moving the pointer on the first screen without any problem. I can use
CTRL-ALT-F1 to
flip to the tty console.
But if I will move the pointer the other screen at this time the pointer hangs
on the right
side of the first screen and the Xserver do nothing any more; all static on the
screen.
CTRL-ALT-BS will not work and CTRL-ALT-F1 will not flip to the terminal console.
I can still log in to the computer remotely via ssh but the Xorg process could
not be killed
with kill nor with kill -9. So I have rebooted the system.
I googled for the error and found something which looks like this is not a
problem
of the nv-driver itself. It's possible a main problem, because I found problem
with ati,
amd and intel gpu's if there more than one gpu is fitted, too.
