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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448102 Title: Kubuntu 15.04: plasmashell crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plasma-workspace/+bug/1448102/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
