Please attach the ouput of "qdbus org.kde.KWin /KWin supportInformation" This would be more like a bug in plasmashell than in kwin (does suspending the compositor revive plasmashell updates?) but ultimately is likely indeed in the driver. Created attachment 95467 [details]

If I suspend the compositor using Alt-F12, plasmashell immediately updates again, yes. (At least if I'm on the Desktop, I've not yet been successful with this in the frozen lock screen, but I'm also not sure if I really successfully managed to unlock the session in this case.) > OpenGL platform interface: EGL Try glx or enable dri3, likely bug #338150 (In reply to Thomas Lübking from comment #6) > > OpenGL platform interface: EGL > Try glx or enable dri3, likely bug #338150 Yes, seems to help! DRI3 is not available in the selection box, but GLX is, and with GLX the GUI does not stall / freeze. Interestingly I did not (actively) change anything concerning this setting on my upgrade, so it worked fine with EGL in Plasma 5.4.3 under Kubuntu 15.04 and just started to fail after the upgrade to 15.10. Due to this I've not yet tagged this bug as a duplicate of #338150, but feel free to do so if you consider it to be one. DRI level can not be configured for clients, it's a setting of the X11 driver. See https://bugs.kde.org/show_bug.cgi?id=338150#c10 (you don't need a complete xorg.conf but can use an include in eg. /etc/X11/xorg.conf.d/20-intel.conf) This may be triggered by an update of the intel driver / mesa. I'll tag this as dupe; if you can deny the DRI3 solution, please feel free to re-open it. *** This bug has been marked as a duplicate of bug 338150 *** |
