The same with me (HP nx8220 PG802EA), both: [System-> logout -> Sleep] & [Power Button -> Sleep] causes appearing logout dialog on resume. Dapper Beta with current updates (2006-04-25).
Also screen is not locked. But this probably due to bug in gnome-screensaver. -- Logout dialog shown after wake-up from sleep https://launchpad.net/bugs/34509 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
