Comment 251 for bug 1220426

I have created a PPA for those using Vivid. The only change is the addition of the upstream patch. https://launchpad.net/~snafu109/+archive/ubuntu/xorg-server

This may be useful for users on Utopic too since both use xserver-xorg 1.16, but there are no guarantees. I installed the package built for Vivid on my machine running Utopic and didn't experience any problems, and it fixed the freezing issue for me as expected.

I can't provide any support for this, sorry. But please comment if you're using Vivid and you try this, whether it does or does not fix the issue.

The debdiff I attached (see comment 247) contains the patch that was applied to the package provided in the PPA. If you try the PPA and it works, that validates the patch I provided.
