I've now tried 2 mainline kernels. 3.8.13-03081302-generic (v3.8.13.2-raring) dated 07-Jun-2013 is working well so far, no issues.
3.9 rc8 dated 21-Apr-2013 is problematic. ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189645 Title: General lag under desktop environments To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
