I've installed Kubuntu 12.04 (latest patches always applied as they become available) and experience an odd thing. Whenever I customize the multi-monitor settings (i.e. tell it to extend the desktop and which monitor to treat as primary) these settings work for the session, but disappear once I reboot.
Can this have to do with the fact that I encrypt my home directory and such settings are stored in there?
Again, I can apply the settings in the active session, but once I reboot they're "forgotten".
