Description of problem: While working in Gnome shell, suddenly the UI freezes and is unresponsive. Mouse arrow moves but clicking around does nothing. Keyboard does nothing, although I can get to a shell. At this point it causes data loss because I can't unfreeze the environment, so whatever I was working on is lost. Version-Release number of selected component (if applicable): kernel 3.11.0-300.fc20.x86_64 xorg-x11-drv-nouveau-1.0.9-2.fc20.x86_64 How reproducible: Transient, but eventual. Steps to Reproduce: Actual results: UI freezes except for mouse arrow. Gnome shell environment is unrecoverable. I can restart gdm usually, but anything I was working on is lost. Expected results: Not this. Additional info:

I wonder if you could try alt+tab or windows key to unfreeze the screen when experience UI problems next time.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20.

Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life.

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.
