Strange nvidia issue partly solved but only temporary

[nabrown65]

I have a self built computer which includes nvidia onboard graphics. (C51G GeForce 6100).
I have the system up and running complete with correct screen resolution and full effects. The system functions very well but only until it is rebooted.
After a reboot I get an black screen only (after the splash) except for a single narrow line at the very top of the screen. The only way that I have been able to get the system back is to switch to a command line (Ctrl+Alt+F1) and install the nvidia-glx-173 driver as a replacement to the 177 one. This doesn't work but on reinstalling the 177 driver and restarting kdm it continues normally with everything working normally. This is inconvenient on a machine that is not left on.

Any suggestions or solutions most gratefully appreciated.

Cheers in advance.

The driver installation process that works for me is here:

When you run sudo envyng -t on the second screen is a choice of driver. The 177.80 version should run that GF 6100, but you can choose the 173.xx if you like it better. :)

The process you mention is one of the many things ive tried before and it still left me with the single line problem. Same issue with envyng -t and installing dirvers through that. The only thing that reliably works is the install the 173.xx driver using apt-get install nvidia-glx-173 then reinstalling sudo apt-get install nvidia-glx-177.
Never got anything out of the 173.xx version in any way.
