I tried your solution, but it still doesn't work. However, I found out this message in the konsole terminal when I executed the plasmashell command: "This program requires an X86 processor that supports SSE2 extension, at least a Pentium 4 or newer."
I'm using an AMD Athlon XP 3000+ CPU. Could it be a problem between my CPU and the new KDE?
