Re: GeForce 6100, SUSE 10.0-64, only 70% of the picture on the screen
According to your X log:
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "1280x1024"
(II) NVIDIA(0): Virtual screen size determined to be 1280 x 1024
You didn't comment out the modelines, as I suggested, so its quite possible that those modelines are invalid (as has been the case with others using SuSE in the past).
If you need further assistance, please start X with the following command:
startx -- -logverbose 5
and then generate and post a new bug report.
