Description safety0ff.bugz 2011-07-23 14:48:43 UTC 
I had recently updated s/w on my computer and noticed that all opengl apps would no longer open.

I believe I have narrowed down the causes to xf86-video-intel, and it seems that enabling sna on latest git causes the issue to arise.

To clarify, currently latest is: 6dbbb74bde034f5f00aee0396ccd1e03a6625fbd
Previous (3e55f3e88b40471706d5cd45c4df4010f8675c75) seems to work fine (so far).
I have i965 / intel 3000 hd graphics.
Comment 3 safety0ff.bugz 2011-07-24 18:14:52 UTC 
I also forgot to mention that the following errors were showing up:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

    sna: Revert enabling scan-line wait on SNB
    
    Hanging the machine does indeed prevent video tearing. Just not quite
    what the user expected...
