I am not sure if this is actually the same bug but the symptoms seem to be consistent; maybe it should be a separate bug report.
I did not have this bug in 12.04 but it showed up after upgrading an existing system to 12.10. It also manifests itself in the exact same way on a brand-new system with a fresh install of 1210. It seems settings (including but not limited to keyboard shortcuts) for certain Compiz plugins are occasionally reset to their default values after a system reboot or crash. I think I have seen this occur after using the compiz settings import/export functionality as an easy workaround, as I have also occasionally lost the settings without reboot. As stepankk mentioned above it seems to affect some shortcuts that use Alt and Super but does not always affect all of them. I have experienced reset settings and shortcuts from the following plugins: General Options, Desktop Wall, Expo, Ubuntu Unity, Move Window, Resize Window, Grid, and Gnome Compatibility. Again, these do not always all revert together. It seems the Move Window, Resize Window, and Grid plugins seem to reset with the most frequency on the new machine and the Ubuntu Unity Plugin settings on the upgraded machine. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/964270 Title: Ubuntu forgets keyboard shortcuts after a restart Status in “gnome-control-center” package in Ubuntu: Opinion Bug description: I use Dell XPS 1640. I'm using the latest ubuntu 12 and updated everything as of today. I assign some shortcuts for music to ubuntu keyboard shortcuts such as when i press ALT + X the music plays/pauses. However, after I restart the system, ubuntu forgets them and I have to reconfigure it everytime. I am new to Ubuntu but willing to help on debugging if it is simple and not technical.
