I've installed the Beta 3 version of F22 KDE Live in a VirtualBox VM. This was a clean install, i.e. get a fresh VM, boot the Live CD image, then install to disk by clicking on the button. My host machine is F21 has plenty of horsepower and an NVidia graphics card under the proprietary driver. I also installed the VBox Guest Additions and ran "dnf update" in the guest. After logging in, the resulting Plasma DE is unusable. Panel menus pop up but windows don't appear on the desktop; in fact nothing appears there except the root background. Other Fedora installations (F21 Workstation) work correctly in the same setup. Since this is KDE specific I thought I'd ask here before taking it to the Test list. poc _______________________________________________ kde mailing list kde@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kde New to KDE4? - get help from http://userbase.kde.org
