Screen briefly appears after suspend despite lock

[DaveAbrahams]

Binary package hint: gnome-power-manager

When I suspend my Dell Inspiron 9300 using the ATI Mobility Radeon x300 with fglrx, and then resume it, before the password dialog appears, I can briefly see the screen exactly as it was before I initiated the suspend. Given that screen lock is intended to protect the machine's owner from unauthorized access to information, it seems like this is a security vulnerability.

I'm using Ubuntu Hardy 8.04 with alll the latest updates.

Is this still a problem in Ubuntu 9.04 or Ubuntu 9.10 Beta?

I don't know. Switched to mac in part because of this dynamic: I go to
the trouble to report a bug; it gets confirmed, but nobody addresses
it so months or years later I am asked if it's present in some newer
version (or even a prerelease!) and the bug is marked incomplete.
Unless I'm willing to keep on top of the status of all the problems I
report in some bleeding-edge version, the bug gets no further
attention and lives on forever.

Thanks for reporting this. This issue should be fixed in Ubuntu 9.10. I am closing this bug. Feel free to reopen this issue if it can be reproduced with the latest release.
