Hello, does anybody know how to install a new video card (pci) on a board with a on-board video chip which could not be disabled by bios or jumper settings? I have a OptiPlex Gx1 450L (Bios Revision A06) board with a ATI 3D Rage Pro AGP 1x/2x video chip on it. Now I want to install a LCD monitor under this system which needs a special video card (digital, Siemens D964). So everything works fine under shell, but I was not able to start X. Also I could not configure the new video card with system-config-display. On starting system-config-display the screen turns to black and the program is searching for the on-board video chip although the monitor is still connected with the new pci video card. To build a working /etc/xorg.conf with this monitor and the pci video card on an other copmuter and copy this file to the OptiPlex system doesn't change anything. So, I am totaly helpless at this point. Does anybody know how to get this working? Has fc3 a possibility to knock out the on-board video chip? thank you Olaf
