Description of problem: after updating all of my xorg packages in the most recent update, gnome 3 goes to fallback mode as if the graphics are not enough. My laptop uses an intel i855-GM for graphics... I was running gnome shell without issues before the update. glxgears shows no 3d issues... 250-300 fps during a quick test. Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1.find laptop with intel 855-gm graphics 2.install most recent updates 3.reboot and log in Actual results: boot to gnome 3 fallback mode Expected results: boot to gnome shell Additional info:
gnome-session blacklists Intel 8xx series chips now: * Wed Apr 27 2011 Owen Taylor <otaylor> - 3.0.1-2 - Add a quick-and-dirty blacklist for Radeon R100, R200, Intel 8xx This is intentional. 8xx chips have many silicon bugs that tend to manifest as system lockups.
Is there a way to undo that? i was not having any issues beofre this... no lock ups or whatever. heck the reason i went to fedora was it did not have bugs with that chip like ubuntu did...
I get fallback as well over here on a box where `gnome-shell --replace` works OK. So how to circumvent this?
