The bug is even worse than I thought at the beginning. Even locking the screen does not work, because some minutes later the screensaver "disappears", and to make matters worse you cannot do anything with the keyboard or mouse. I had to Ctrl+Alt+Backspace
By the way, I am submitting the same to the upstream, as similar bugs have been happening for many years and in different distros. I am copying one reflection that I submitted to the upstream. Maybe I was a bit tough, but that is because I am annoyed that a package so simple, and at the same time so important in a desktop, is being so buggy for so many years. The reflection I submitted to the upstream is the following: ------------------- Reflection (maybe tough, but I hope not a flame): I had to quit using translucencies, and why? Because a malfunction of kwin? No. Because a malfunction of the video driver? No. Because a malfunction of the screensaver. I do not know much about computing, but I think a screensaver must not be so tricky as kwin or the video driver. kscreensaver is being malfunctioning for many years, with and without translucencies: not autostarting, starting but disappearing thereafter, etc. Although a desktop is terrific (KDE), if the screensaver does not work, users may think of switching to other desktops (gnome, xfce, etc). -------------------
