Comment 16 for bug 1467595

FYI, for unrelated reasons, I started using the 4.0 from wily and the 4.1 kernel from https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/. I was able to run an X/Unity session under the 4.1.0-1.1~dogfoodv1 kernel for two days without rebooting without the cursor disappearing (I am now using 4.1.0.1.1~rc2 since it has a fix for bug #1473560).

If someone is looking to bisect this, it might be worth starting with the 4.0 kernel that is in wily now. I was using that (with microphone patches for bug #1473560) for a while and never saw the cursor go away (but I'm not sure the longest I ran a session though).
