From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.12) Gecko/20080208 Fedora/2.0.0.12-1.fc8 Firefox/2.0.0.12 Description of problem: In control center select the "science" screen saver. The test button works as expected, showing the warping of the desktop. Clicking on the "lock the session" in the "Lock/Logout Buttons" kicker applet blacks the screen but still requires a password to resume the session. I'm using the nvidia display driver, but I'm guessing the problem isn't there. Version-Release number of selected component (if applicable): kdebase-3.5.9-3.fc8 How reproducible: Always Steps to Reproduce: 1. Select the "science" screen saver 2. Lock the session Actual Results: I see a black screen. Touching the touchpad or any key activates the password request dialog. Expected Results: The screen image should remain visible so the science screen saver can warp it. It might be warping the black screen, I can't tell. Additional info:
Keeping screen contents displayed when the screen is locked is a security risk, so I'm not convinced that this isn't intentional.
The reason I use the science screen saver is for security reasons. When I'm about to lock the session I display something that isn't security sensitive, plus the clock on the bottom-right in the kicker panel. When I come back to the screen that clock had better be showing the same time as the time I left it. I can't guarantee my password is unique, and I can't guarantee that someone can't hack my system and write software that can recreate the screen at a particular time, but my memory of statistics tells me that combining unlikely things A and B is A*B - even less likely. When it comes down to security, anything helps.
The "science" KDE screen saver is working OK now - even though I didn't do any yum updates, just a couple of reboots. Go figure.
good to hear.
It happened again. I also noticed that the tool-tip for the "lock the session" button on the kicker applet. I usually hibernate rather than reboot. A reboot solved the problem.
Oops! I also noticed that the tool-tip for the "lock the session" button on the kicker applet _didn't appear when I hovered the mouse over it._
