I have a similar issue with KDE with bumblebee, namely that drawing on the screen is very sluggish and in some cases fails to work at all. Presumably because of the problem with the nvidia driver you mentioned, bumblebeed fails to start. My (inexplicable) workaround is to open System Settings, and toggle the "Enable compositor on startup" setting on and off again, after which everything works fine again. In theory, this should do nothing since I am not restarting KDE, but in the short term it works. I actually first noticed this on 23 May when using the kernel:HEAD repository with beta versions of the 4.6 kernel packaged (to fix an unrelated issue with screen flickering after turning the screen off and on again). Since I am using the intel card to draw the desktop, whereas you are using the nvidia card, I presume these are different issues, but I wanted to not the similarity in hopes it helps. Also, if anyone wants to point me in the right direction for any information to provide to file a bug report, please do. - Sonny -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
