Back from vacations and it's looks like the issue is not or not entirely in kernel.
I'm back to 3.13.0-24-generic and just installed gnome-shell 3.12 and the problem is gone. I can now safely close and open the lid. So, looks like that at least a 'trigger' for the freeze is somewhere in Unity/compiz. Gonna try again several different kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310823 Title: [Dell Inspiron 1525] Ubuntu freezes when lid closed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1310823/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
