I'm running a Gainward 6800GS 512Mb Graphics Card (obviously NVidia) under Zenwalk Linux. The installation went perfectly with the latest release (March 7th) and it was running fine until I turned off.

I start up again, get the bootloader but as soon as the login manager should have started up "Attention: No Signal".

I can swap into text mode but can't find any errors in the x server log. I've had this previously and never found a fix aside from reinstalling the video card drivers - which I don't want to have to do every time.

I've done (I think it was called this) a sanity check on the driver that's installed and it's reported that the driver has changed since it was installed. Why would this have happened? It doesn't quite make sense.

Any help appreciated,
