Description Adam Williamson 2009-01-16 13:25:19 UTC 
hw/xfree86/common/xf86AutoConfig.c in xorg-server blindly uses the 'nv' driver for any card with 0x10DE as its PCI vendor ID. However, quite a few NVIDIA cards don't actually work with the 'nv' driver. I made a list of reports of cards that completely fail to work with nv:

http://bugs.freedesktop.org/show_bug.cgi?id=17526 - 0849
http://bugs.freedesktop.org/show_bug.cgi?id=18092 - 0848
http://bugs.freedesktop.org/show_bug.cgi?id=19545 - 0863
http://bugs.freedesktop.org/show_bug.cgi?id=19617 - 0641

also add 053A to the list (reported in a Mandriva bug). I am currently testing a patch which should use vesa for all those devices instead, effectively a blacklist. I'll attach that once I've tested it here. This is important, because it breaks distros which rely on X autodetection and use the detected driver during install - like Fedora. If you try to install Fedora on an affected card, you'll just get a black screen.

Should be working in nv 2.1.18.
