Tried most things out there - removed nomodeset from grub; and tried setting gnome-shell to play nicely using 'gnome-shell --replace' but still no joy - got error message: gnome-shell --replace failed to create drawable (gnome-shell:3414): Clutter-CRITICAL **: Unable to initialize Clutter: Unable to select the newly created GLX context Window manager error: Unable to initialize Clutter. Version-Release number of selected component (if applicable): gnome-shell --version GNOME Shell 3.0.2 Kernel: 2.6.38.8-35.fc15.x86_64 Kernel Version: How reproducible: Just start up desktop - Gnome reports that is dropping back to FallBack mode. Steps to Reproduce: 1. Try to start Gnome 3 - gnome shell - reports that it is going into fallback mode 2. try to manually swap over - fails with the above error message 3.

I am having similar problems on a Lenovo G560. gnome-shell only starts in fall-back mode. Same device, same driver. Was working as expected in Fedora 14 w/Gnome 2.x. Additionally it looks to me like there is no real hardware rendering. Programs that used to deliver under Fedora 14 a framerate of approx 10 are delivering about one frame per 10 sec. So I believe the fundamental issue is just that hardware acceleration isn't working. A few other things that might be factors: This is an x86-64 system. It claims DRI is working but it doesn't seem to be.
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
