I was using Ubuntu 11.10 with cairo dock version 2.4 without a problem.
Now, after the upgrade via a clean install of Ubuntu 12.04 amd64 with cairo dock 3.x the system freezes and i have to restart. Machine is acer with core i3 2nd generation and 6gb ram. Is this a known bug ? Is there a workaround ?
I am a beginner with Ubuntu
