This appears to affect both 755s and 760s (Radeon HD 2400 and 3450 respectively). Killing gnome-display-manager has no effect, nor does punting Compiz. Rebooting seems to be the only solution. Nothing interesting in the logs. We should document this or file a bug upstream or something." defect closed normal Upstream Utopia -- ignored LP:366687
