I would like to debug the system when it's in the frozen state, but I can't do that if I don't know how to lock it up :/ -- You are receiving this mail because: You are on the CC list for the bug.

The whole screen appears frozen, only mouse cursor moves. It was triggered in few minutes of playing a fullscreen game. It was caused by kwin (compositor) being stuck waiting for response from X server to a DRI2GetBuffersWithFormat request. Kwin was trying to render the windows using opengl and the DRI2GetBuffersWithFormat request was made from somewhere deep inside Mesa. I analyzed it briefly and X server seemed fine, no threads stuck, responding fine to other X clients, nothing in log. There was nothing in kernel log either. (In reply to Mikhail Ramendik from comment #0)

When one switches compositing from OpenGL to XRender, freezes no longer occur.

I used this as workaround as well and no longer pursued it. I can get the system again and collect backtrace or other information if needed. Google search suggested that it may be some race condition in kwin or xcb. The fact that it happens sooner when the system is busy and screen repaints often would support that. -- You are receiving this mail because: You are on the CC list for the bug.
