Are you able to attempt this again with the most recent versions of both the kernel and xorg-x11-drv-nouveau and report what you see?

Comment 9 Gene Stuckey 2009-04-09 19:46:49 EDT
I've tried with the latest rawhide with the same behavior as noted before. It works with nouveau.modeset=1, but without that, Xorg consumes 100% of the CPU and it remains a blank screen.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Comment 11 Ben Skeggs 2009-08-23 20:37:55 EDT
Kernel modesetting is now the preferred and default path in rawhide, the userspace modesetting paths are now considered deprecated upstream, so closing this as fixed in rawhide.
