... well, I would post an attachment, if Launchpad didn't appear to crash out on my when I do (Chrome or Firefox browsers. I'll preserve the crash dump and try again later. Meanwhile, below is what's in syslog for the crash, and:

After that it comes back and resumes as normal, seemingly replaying mouse and keyboard events from the meantime. I think it's always happened when using Google Chrome (Stable - currently 37.0.2062.94, but I think other recent versions). The desktop is completely unresponsive This didn't seem to happen until a few weeks ago. I tend to pull updates fairly regularly. In syslog there is: kernel: [277415.130771] [drm] stuck on render ring I suspect this is a dupe since I see other related bugs, but you'd be better placed to decide that than I.
