Comment 47 for bug 36581

I renamed gam_server to gam_server.disabled and my system is now running well.

I don't know what the consequences of this action are. Someone else said that they had done it and they had had few problems.

So do it at your own risk.

For me, the choice was to rename gam_server or stop using ubuntu/kubuntu.
