Problem setting up dual monitors on Debian Lenny (Nvidia Quadro NVS 295)

Asked by , Edited by Fernando C. Estrada [ Admin ]

I’m trying to get dual monitors going on Debian Lenny (2.6.26-2-amd64). The system is a Dell Precision T5500 with a Quadro NVS 295 dual-head graphics card from Nvidia. The two monitors in question are a ViewSonic VX922 (1280x1024) and a Dell P2210 (1680x1050).


I tried setting up this in xorg.conf:

X wouldn’t start with that. I used X -configure which generated this:

And that also failed to start X properly. Here’s the output from the X log file:

Fatal server error:

Any help would be greatly appreciated!

Hints:
In the first configuration you are using the “nv” driver which is the free driver, not the proprietary NVidia driver.

In the first config, you have two separate devices listed, which is probably wrong.

Do you have the correct nvidia package installed for your video card?

: please use comments section to provide such informations. This is *not* an answer to your question, is it?

The way I see it, so far, the easiest way to achieve double screen functionality is to  install the proprietary nvidia drivers and set two monitors in nvidia-settings (depending on how you install drivers, you may need to install additional package [mentioned earlier nvidia-settings and nvidia-xconfig]). You will see an option to generate /etc/X11/xorg.conf file for you with needed options. Now I'll show you working solution I'm using myself:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 260.19.06  (buildd@palmer)  Mon Oct  4 16:01:38 UTC 2010

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 1.0  (buildmeister@builder75)  Thu Apr 22 11:44:23 PDT 2010
