If I boot under kernel-4.2.3-200.fc22.x86_64 and log into the KDE desktop after the progress bar screen I get a black screen with nothing showing. I can Alt-F2 and run konsole and it will show up. Booting back into kernel-4.1.10-200.fc22.x86_64 I have no problems with KDE desktop. Has anyone else seen this behaviour? Barry
