+++ This bug was initially created as a clone of Bug #230629 +++ Version: (using KDE 4.3.5) OS: Linux Installed from: openSUSE RPMs I goto Personal Settings -> Desktop: - I have "Enable Desktop Effects" enabled/checked. - I click the "All Effects" tab. - I go to the option, "Logout - Desaturate the desktop when display the Logout Dialog" and disabled/uncheck it. If I click the Leave button to logout, the desktop DOES NOT Desaturate. Good, but... I cancel the logout. I click Leave again, and logout for real this time. I login and click the Leave button. The desktop DOES Desaturate this time. Bad!!! I double-check the option, and it is still disabled/unchecked. Desaturate desktop is causing another problem. If a user is logged-in through VNC, the Desaturate desktop is causing great pains because it is soooo slow. The VNC user does not have "Enable desktop effects" enabled/checked, but their desktop still Desaturates when they select the Leave button to logout.
CONFIRMED REPRODUCIBLE Debian 6.0 Kwin 4.4.5 Make sure the compositing effect "Logout" is not active. Suspend compositing and then re-enable it (Left Shift + Alt + F12 -- twice) The "normal" logout effect is now active while compositing is active, which it shouldn't be. here is how to restore the correct functionality: kquitapp kwin && sleep 10s && rm -f $(kde4-config --localprefix)/share/config/kwin* && kwin --replace & After the preceding commands have executed and kwin is running again, Desktop Effects can be enabled, the Logout effect can be deactivated, and once the logout dialog is opened there will be no effect applied. If at any point compositing is suspended and then re-enabled the problem will return. I can't find what setting might be affecting this.
I dont think I know exactly how to use this bugzilla thing, sorry for what may be apparent spam.
