Things I would try: 1-Purge xserver-xorg-video-nouveau (IOW, does default modesetting driver find three connected displays?). 2-Check if a Knoppix boot generates similar failure. 3-Swap the two cards between PCIe slots. 4-Can you get output on two displays if you remove the Quadro (IOW, will the GeForce work at all)? 5-Try a DVI cable type with the GeForce/Sharp if the Sharp has a DVI port. 6-Try the GeForce with a DVI-to-HDMI adapter and HDMI cable. 7-Try a different HDMI port on the Sharp if it has more than one. 8-Report http://www.ucl.ac.uk/~ucecesf/tmp/xorglog.txt and failure on one of the lists devoted to Xorg hardware issues, such as xorg-de...@lists.x.org or x...@freedesktop.org. -- "Wisdom is supreme; therefore get wisdom.
