I am unable to enable desktop effects on ubuntu 10.04 32bit desktop , after installing Nvidia developer drivers 260.19.26. The output is shown below:

Moreover I am unable to run other code samples in "nvidia GPU computing SDK" excepts deviceQuery.
Here is the output of deviceQuery:

Using the same card with the Nvidia current 260.19 .06 and Compiz ccsm successfully. Is there anything in the driver release notes offer any clues ?

The 8400GS is a main stream entry level card are there any direct benefits to using those drivers ?
