Bug Description

Suspend works alright on my Asus 62E (Zareason lightlap) but when I wake the machine up from suspending, it briefly shows the entire screen contents before giving a pssword /login prompt to allow the user to authenticate. This means anyone coming across the machine when asleep can get a glimpse (it's more than a glimpse, often) of whatever was in veiwe before sleep was engaged. This is a privacy / security threat. Moreover, it didn't used to happen until 8.10 (I believe) or some update since. Is it just that some graphics buffer needs to be cleared before sleeping?

 lsb_release -rd

Thanks for this bug report. Does this problem still occur in a recent Ubuntu release like Karmic?

It appears to me no longer to occur in Karmic.
I'm marking it fixed.
