Bug Description
Unity froze on my when initiating the workspace switcher (which had been working previously in the same session). I switched to ctrl+alt+F1 to get to a command prompt, ran unity --replace, but that kept crashing.
Output from unity --replace:

Seems like an IO error with the driver lock. Weird, this should never happen.
Is this fixed now? If not, try rebooting. If that doesn't fix this, it's a driver bug.
