[OCLUG-Tech] Possible dying graphics adapter

Last week, I indulged my fondness for Debian (-based distributions) and good coffee with a wallpaper that combines the two:

There are problems. The background is a (bright?) white. The area between the two horizontal frame bars always deteriorates rapidly into colour splotches.I have previously understood this to be an early sign of the pending death of my graphics adapter.

I would be surprised if this image were over-taxing my graphics adapter, but perhaps I am not judging well the requirements of modern DEs. This is the only image  I have run recently which gives this kind of problem.

I am running Kubuntu Karmic (9.10) Alpha on a Core 2 Duo with 4 GB RAM. According to lshw, the graphics adapter is:

display
                description: VGA compatible controller
                product: G70 [GeForce 7600 GS]
                vendor: nVidia Corporation
                physical id: 0
                bus info: pci@0000:01:00.0
                version: a1
                width: 64 bits
                clock: 33MHz
                capabilities: pm msi pciexpress bus_master cap_list
                configuration: driver=nvidia latency=0 module=nvidia

Should I be talking to the vendor about the graphics card? The machine is still under warranty.

Thanks in advance
Bruce
