When I login to Plasma5 on my netbook I get a white screen and a lot of crashes of plasmashell, it doesn't matter if kwin compositing is turned on or off at login time Reproducible: Always Steps to Reproduce: 1. Log in to Plasma 5 2. See completely white ksplash and white plasma, alt+f2 shows a white krunner 3. See plasmashell crash while trying to paint the control panel Actual Results: plasmashell, ksplash and krunner (when using alt+f2) stay white, plasmashell crashes several times in a row (see backtrace) without starting to work normal Expected Results: No white screen, no crashes When I restart kwin (DISPLAY=:0 kwin_x11 --replace &) from a tty, the problems get fixed, trying the same using krunner ("kwin_x11 --replace") only restarts kwin. Hardware is a Samsung NC10+ running Kubuntu vivid, if additional information about the system is needed I will be happy to provide it. Graphics configuration should be completely Kubuntu default. -- Backtrace: Application: plasmashell (plasmashell), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

can you paste the output of qdbus org.kde.kwin /KWin org.kde.KWin.supportInformation please Can you also include the output if you try and run plasmashell from a command line. It looks from your backtrace that you have a graphic card/opengl drivers so old they can't compile shaders.
Hi David, Both outputs before restarting kwin (everything plasma-related white and crashing): http://pastebin.com/xgFF6gkb Both outputs after restarting kwin (everything working as expected): http://pastebin.com/J2P1aFkZ I hope that helps.
> Compositing Type: XRender This is likely the problem. Plasma requires OpenGL at least v2. Can you reproduce this with selecting OpenGL2 as compositing backend?
No response to comment #3 for a long time, assuming fixed. If you can try Plasma 5.5 with OpenGL backend and this still happens, please reopen this report with new information. Thanks
