I have had this issue since karmic; still here in oneiric. I think there's some sort of race condition, because SOMETIMES it will come back and allow me to unlock the X session and THEN lock; other times it comes back to a blank screen.
Attached my kern.log from just after filesystems were mounted this morning until the point I power cycled now. ** Attachment added: "zevans23 kern.log" https://bugs.launchpad.net/ubuntu/oneiric/+source/linux/+bug/759213/+attachment/2348426/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/759213 Title: [HP Compaq 6005 Pro] Suspend does not resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/759213/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
