Re: GeForce 6100, SUSE 10.0-64, only 70% of the picture on the screen
In your X log, I see:
(WW) NVIDIA(0): No valid modes for "default"; removing.
(WW) NVIDIA(0): Unable to validate any modes; falling back to the default mode
(WW) NVIDIA(0): "nvidia-auto-select".
Because you're requesting a mode called "default" which doesn't exist in your xorg.conf.
I'd suggest commenting out all the modelines in your xorg.conf, and requesting a valid mode name (1280x1024).
