The backstory: I bought a new el-cheapo multi-function printer-scanner today and as a consequence installed sane, xsane, and kdegraphics-ksaneplugin. I did all that while logged into my usual window manager, dwm. All was fine.

Then I wanted to try the kde plugin, so logged into kde desktop and was presented with what appeared to be the blue screen of death (sometimes black). Plasma seems to start fine, i.e., splash screen goes through its usual motions, then the blue/black screen appears when the desktop usually does.

Can you kill plasmashell and start it again from the terminal, and provide output?

i.e from krunner (alt+f2) open konsole, killall plasmashell && plasmashell

Thanks, everybody. Since everyone's questions, and the answers, all are related, I'll respond to Marshall, Bhushan, and Ralf all in this response: I've killed and restarted plasmashell and here is the output: ~ $ killall plasmashell && plasmashell kscreen: launcherDataAvailable: "org.kde.KScreen.Backend.XRandR" kscreen: Primary output changed from KScreen::Output(Id: 587 , Name: "DVI-I-2" ) ( "DVI-I-2" ) to KScreen::Output(Id: 587 , Name: "DVI-I-2" ) ( "DVI-I-2" ) unversioned plugin detected, may result in instability unversioned plugin detected, may result in instability unversioned plugin detected, may result in instability unversioned plugin detected, may result in instability unversioned plugin detected, may result in instability unversioned plugin detected, may result in instability unversioned plugin detected, may result in instability unversioned plugin detected, may result in instability unversioned plugin detected, may result in instability last screen is < 0 so putting containment on screen 0 kscreen: Launcher finished with exit code 1 , status 0 kscreen: Service for requested backend already running Plasma Shell startup completed kscreen: Primary output changed from KScreen::Output(Id: 587 , Name: "DVI-I-2" ) ( "DVI-I-2" ) to KScreen::Output(Id: 587 , Name: "DVI-I-2" ) ( "DVI-I-2" ) I don't normally have an .xsession-errors file, but I created one and here is the output from starting a session: X.Org X Server 1.17.2 Release Date: 2015-06-16 X Protocol Version 11, Revision 0 Build Operating System: Linux 4.0.4-2-ARCH x86_64 Current Operating System: Linux arch 4.2.3-1-ARCH #1 SMP PREEMPT Sat Oct 3 18:52:50 CEST 2015 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=f72c94ff-cf1f-42dd-9d10-ab716a64b067 rw Build Date: 17 July 2015 05:38:19PM Current version of pixman: 0.32.8 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

Any thoughts?
