Version: 4.5 (using Devel) OS: Linux I just compiled the KDE 4.5 branch (which will become KDE 4.5.2) with kdesvn-build for a completly new user. The install inside of the new user is completly fresh, there were no old config files. When I use systemsettings nearly every click on "Apply" causes the desktop to freeze completly. All I can do is hitting Strg+Alt+Backspace. When restarting the desktop, the change I made in systemsettings has taken place. It makes no difference in which kcm module I make the change. I had the freeze after altering desktop effects, after altering some kwin settings and after changing the widget style. Can someone reproduce this? I run this on a Fedora 13 on an intel laptop with i965 graphic chipset. Reproducible: Sometimes Steps to Reproduce: Change config in systemsettings and click on "Apply"
You can hit Alt+Shift+F12 twice instead of killing X. *** This bug has been marked as a duplicate of bug 241402 ***
