Thanks everyone for the input and for confirming this is caused by the nvidia driver.
Those who still experience the bug with nvidia-319.xx (which reportedly should work) could you please try nouveau to make sure it's not yet another issue in the binary drivers? If you can reproduce the problem with nouveau, please open a new bug report. We will use this one to track only the nvidia-related issue. I'll close this as UPSTREAM, since we can't do anything about it. As recommended in comments above, either wait for nvidia to release an update, downgrade to nvdia-319.xx or switch to the open source nouveau driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1245979 Title: After Upgrade to Kubuntu 13.10 akondai fails to register at d-bus session, making kde-pim suit unusable To manage notifications about this bug go to: https://bugs.launchpad.net/akonadi/+bug/1245979/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
