Description of problem: My machine has nVidia GeForce 6150SE nForce 430 video. The mesa-drivers-dri-experimental 3D support gives a totally corrupted display (both F13 and F14), so I have to use the proprietary nVidia driver to get working 3D support. Unfortunately, Rawhide doesn't appear to realize that the built-in 3D doesn't work, so am left with an unusable system (unless I can force it to fall back somehow in order to be able to install the proprietary driver first). Bug 581769 looks like my problem except that it refers to compiz, and my problem happens even without desktop effects enabled. Smolt URL: http://www.smolts.org/client/show/pub_e6c78f7d-d38c-47df-8f06-47696b5c01b3 Version-Release number of selected component (if applicable): whatever is on http://adamwill.fedorapeople.org/gnome3_test_day_20110203/gnome3_test_20110203.iso (the 64-bit live image)
I'm not sure if being able to detect the 3D support being present but buggy is a realistic ask of the fallback code; if not, we should re-assign this to nouveau and fix the corruption.
I booted from the 32-bit Gnome3 test day image (I don't have the 64-bit image at the moment, but the symptoms are the same either way) with the kernel options drm.debug=14 log_buf_len=16M, logged into VT2 as root (since graphical mode is unusable), and collected the following log files. I can't get glxinfo output since it can't open the display on VT2. There is no xorg.conf file, and only the one Xorg.*.log file.

On the Nouveau test day, things look much better - Gnome shell actually works (with a few glitches). I posted my results on the wiki.
Using Fedora-15-Alpha-i686-Live-Desktop, one day it works fine, the next day I get the corrupted display, even after powering down and rebooting. So whatever the fix was, doesn't seem to be reliable. The 2011-03-10 Gnome3 test day image seems to work fine each time I tested it (only a few times, though).
Gnome Shell seems to work okay in F15 Final (AKA RC3), both with nouveau and the proprietary nvidia driver from Rpmfusion. Closing.
