Default triplehead with two nvidia-cards and twinview

Hello,

i have a nvs-290 with two displays attached running with twinview very nice.

I would like to attach another display. Is it possible to install a second nvs-290 and using twinview?

Is it possible to install an other nvidia-card which uses the 280 linux driver and runs it with the nvs-290 in twinview with three displays?

Thank you

regards
Andreas

You can keep the twinview screen for the two LCDs attached to the first nvs-290,
but the third LCD will be a separate X screen. You can then use all three LCDs
for a single desktop (including 3D acceleration) when enabling Xinerama.
However, such a configuration has pros and cons - for detail, please check
posting #2 of the following thread:

In theory, any other (even non-nvidia) cards should work alongside the nvs-290
with Xinerama, but you may not have accelerated 3D support for the third display:
OpenGL only works if the (nvidia) GPUs are of the "same" family. I don't know if a
GTX 280 is similar enough to an nvs-290.

Thank you very much.

If I would use the Matrox TripleHead2Go, what happens when maximizing a window?
Is it maximized to both Displays connected at the Matrox?

There is only one solution if the window must be maximized to one display, isn't there?
I think, all Displays have to be a seperate x-screen, combinded with xinerama.

Andreas

You can define the window maximisation behaviour as desired by using
the "TwinViewXineramaInfoOverride" option. I.e. let's assume you have
three 1600x1200 displays, so you would attach the first LCD to the
first output of the video card and the other two displays to the second
output of the video card via the TH2G (or DH2G if VGA is ok). If you
want to maximize windows to each LCD, then add the following line
in xorg.conf:

Code:
Option "TwinViewXineramaInfoOverride" "1600x1200+0+0, 1600x1200+1600+0, 1600x1200+3200+0"
For details and configuration examples, please check the following threads:

Hi,

wow, that's really great.

I would connect two 19" Displays at 1280x1024 to the DH2go. The DH2go would be connected to port 2 of the nvidia card.
The 26" Display at 1920x1200 would be connected to port 1 of the nvidia card.

The twinview configuration would see two displays: 1920x1200 and 2560x1024.

The displays would be placed like this:
1280x1024 1280x1024 1920x1200

Option "TwinViewXineramaInfoOverride" "1280x1024+0+0, 1280x1024+1280+0, 1920x1200+2560+0"

Is that correct?

regards from munich

Hi!

Unfortunately, I have no experiences with "asymmetric" twinview setups.
AFAIK, you would also need to define appropriate metamodes for such a
case, but I don't know any details on that topic, sorry.

Hi

I just tried to simulate it. It works great. :-)

Currenty i have a twinview setup with two 1280x1024 displays.

I added following to my xorg.conf:
Option "TwinViewXineramaInfoOverride" "1280x1024+0+0, 640x1024+1280+0, 640x640+1920+0"

Then I tried to maximize the windows -> look at the screenshot. :-)

I'm really happy. Thank you very much!

regards
Andreas

Could you possibly share your whole config file? I've been trying to get my dual setup running properly with 2 video cards. Seems to be just plenty out there on 1 card with two, but not 2 cards with 2 monitors.

Here's a quad output setup off two cards, on a 64bit CentOS machine.

Hope that's of interest.
