External Display Problem on Dell Inspiron 8600 w/ nVidia card and Redhat 9
My Dell Inspiron 8600 has a 15.4" widescreen WSXGA+ display from Hitachi suporting 1680x1050 resolution. It has an nVidia GeForce FX Go5200 video card with 32MB RAM.
I seem to have Redhat 9 working on it for the most part except for the external display. I have downloaded and installed the nvidia 4363 driver and included the 16:10 modelines in my XF86Config file to support the widescreen display. The laptop LCD display works great. Unfortunately when I switch to the external monitor using the twinview features in 1280x1024 mode, the picture on the monitor is not good. It keeps shaking, its not a steady picture, as if the refresh rate or frequencies were incorrect. I have tried 4 different monitors, and 2 projectors. I have also tried all the drivers since the 4363 version. I have also played with the frequencies in the monitor section of the XF86Config file. None of it seem to make any difference.
Has anyone run into this before? Any suggestions?
