Yesterday I bought components for a new system including the Asus 210 Silent videocard (1GB DDR3 memory). After building the system I installed Scientific Linux 6 (x86_64) on it and the Linux x64 (AMD64/EM64T) display driver version 256.53 (as suggested on the Nvidia Download Driver
page. It all seemed to work fine except than on several occasions the graphical display (X-server) seemed to reboot/respawn without cause presenting me the Gnome login screen. Unfortunately the logfiles didn't give any clue as what happened.
After some trying I found a way to reproduce the problem. By booting into runlevel 3 and starting X by hand I found that by starting "glxgears" and grabbing the glxgears window (showing the rotating wheels) and moving it around quickly I found several "errors" in the logfiles (glxgears died with a "segmentation" error).

When I disabled the Nvidia driver and ran the default driver the glxgears-test didn't cause any problem.
This leads me to believe that the problem lies with the Nvidia driver.
Since the driver is from august last year, could it be a mismatch with Scientific Linux 6 (a rebuild from Red Hat Enterprise Linux)?
RHEL (and all the clones including Scientific Linux) do not come with their own Nvidia driver (except the default nv driver). So I need to use the one from Nvidia or any of the 3rd party repos (which wouldn't be my first choice).
There seems to no newer driver for the EN210 Silent card.
Of course I tried the latest 275.09.07 driver, but alas, no improvement.
I wondering if there is a solution or should I replace the card with one that is supported by the 275.09.07 driver (like the 9500GT I'm using without any problem) ??
