This report is related to the bug 304239 reported few month ago. I have experienced again this problem. The "logout effect" doesn't works yet. I use KDE with "desktop effects" disabled and I don't see a "fade to grey" when I attempt a logout/shutdown/reboot. I see a black screen under the dialog box In KDE version 4.7 and earlier the "logout effect" works also when the desktop effects are disabled I see that the "logout effect" is broken from kde 4.8.x Reproducible: Always Steps to Reproduce: 1. download a linux live distribution with a recent KDE environment, I have tried the last kubuntu http://cdimage.ubuntu.com/kubuntu/releases/raring/alpha-2/raring-desktop-i386.iso 2. run the image on a real machine (I have tried a machine with a radeon card) or with qemu (I have tried with the standrad video driver) 3. KDE is starting with desktop effect disabled (if not, disable it) 4. try to logout Actual Results: the screen under the dialog became black Expected Results: the screen under the dialog box must show an animation: a fade to grey of the screen
I have tried the latest KDE in the latest Fedora Live CD http://fedoraproject.org/it/download-splash?file=http://download.fedoraproject.org/pub/fedora/linux/releases/19/Live/x86_64/Fedora-Live-KDE-x86_64-19-1.iso fading works if I use: desktop effect enabled + radeon xorg driver desktop effect enabled + default xorg driver on qemu desktop effect disabled + default xorg driver on qemu But doesn't works if I use desktop effect disabled + radeon xorg driver I understand that is a strange combination, but the fading on logout should work also with a full graphics driver.
There's no black background anymore. We won't bring back the ancient grayscale effect, though, that's what the composited logout effect is for.
