[SOLVED]Blender freezes system with nVidia Quadro and nVidia vers. 346

I an unable to run blender on  my system:

Dell T3600 (Xeon-based workststion)
card: nVidia Quadro 2000
drivers: latest nvidia package (346.35-5)
dual screen configuration

I use the Razor-qt desktop environment.

Launching blender completely freezes the system and a hard reset is needed. Any suggestion on how to find out what is wrong?
I tried searching the forums and other online sources but came up empty, probably because I do not really know what to search for.
(In fact I am not even sure this is the right arch forum for this question...)
I never used blender before, and in fact I only need it because a robotic simulation environment I'd like to use (morse) is built on top of it.

Help greatly appreciated.

Stefano

Do any error messages get displayed before a lockup if you run blender from a terminal?

Do any error messages get displayed before a lockup if you run blender from a terminal?

More details:

1. No error messages appear on the console after Blender is started. In fact, no messages at all

2. The problem is with Xorg: after Blender is launched, it goes to 100% CPU for a while (a minute or two), then it goes back to normal.
    However, any window-related event (e.g. clicking) brings it back to 100%. Interestingly, after every lock up it takes longer to come back
    to normal. After three or four times, it locks up solid (checked with top running in a terminal from a ssh-connected machine)

3. Blender itself seem to consume very few resources, at least according to top

After further experiments, I can obtain the same behavior (total system lockup) with different applications,
so the problem is not related to Blender. The applications are all robotic simulators (Gazebo, V-Rep, player-stage, Webots, Morse).
In some cases (V-Rep, player-stage), the lock up only happens when moving the app's window between the tow physical monitors,
or between virtual desktops. In other cases  (Gazebo, Blender-based Morse), the lockup happens when the application starts

The only conclusion I can draw is that the problem has nothing to do with Blender---may be it is an  openGL issue related to the nVidia driver.

In any case, I am marking the issue as Closed

All right---didn't know that.
