Description of Problem: For the latest kdebase-2.2-4 rpms when one chooses Bouboule or Rock (or few others) for a screensaver then tries to lock the screen no screensaver will show. Only the password box with a frozen background will show instead. For Polygon, Lines etc. everything works fine. None of the GL savers work either. ALL savers work/test correctly in the kscreensaver windows!! This has been reported to KDE bugs as well by few people but I noticed that they also used RedHat packages. Not clear whether a packaging issue or a KDE bug. Version-Release number of selected component (if applicable): kdebase-2.2-4 How Reproducible: Always Steps to Reproduce: 1. Select Bouboule from the kscreensaver menu 2. Try to lock the screen 3. Actual Results: Expected Results: Additional Information:
We (Red Hat) should really try to fix this before next release.
KLock actually does the right thing and calls e.g. kbouboule.kss --root. Running kbouboule.kss --root from a konsole or xterm doesn't work either. This is definitely not a packaging problem; looks like the screensaver can't grab the root window for some reason. Might be an X problem; debugging.
After some more debugging, I believe it's an X problem: XSetForeground() , XFillRectangle() etc. don't seem to have any effect even though they're called on the correct (root) window.
On another look, maybe it isn't after all - kdesktop seems to be showing on top of the screensaver (running the thing from a failsafe session (twm + xterm) works). (Might still be an X problem though; I'm not sure how somewhat conflicting low-level X calls should be handled)

Found it. The problem is that KDesktop is no longer drawing its background and icons on the root window itself - the screensavers are displayed under KDesktop. The screensavers need to be displayed on KDesktop's window rather than the real root window.
Fixed in kdebase 2.2-9
