Just for the record, I am experiencing similar problems: X (or KDE) becoming almost unusably slow. FWIW, I have a Lenovo Z61m with a Radeon Mobility X1400 chipset. When I'm just working on the notebook display, everything is fine usually, but when I connect a separate display, performance decreases a lot. Suspend works fine for me, though. With 4.4.2, I even get a nice notification that the display settings have changed afer having plugged the notebook in the docking station and waking up from suspend. > In my opinion, there is something wrong KDE/Plasma and its use of OpenGL. > Before this experience, I blamed nvidia and was looking > for changing my laptop and use ATI but now I definitely blame KDE/Plasma Have you tried not using desktop effects? Does that make a difference? Cheers, Carsten
