So, decided to test run Kubuntu 15.04 for having latest Plasma desktop. Install went smooth alongside my Kubuntu 14.10 and Windows 8.1.

1. Booting into the system, i simply can’t access any of the WiFi either with hidden SSID or broadcasted one. I’d get the following message.

2. The start menu also froze which when force-fully killed, the whole desktop and taskbar was gone leaving only applications open. I could still switch between them by putting my cursor on the top left corner which displays all open apps.

3. I also notice that when running System Monitor (ksysguard) from KRUnner by pressing ALT+F2, the KRunner would not disapear unless i close System Monitor again.

And when I would close it, I’d get this error message then KRunner closes.

Final Notes:
I can say Kubuntu 15.04 is really really fast. Dolphin, System Monitor, Firefox open like in a breeze. It feels like on an SSD. But unfortunately I won’t be able to test more as I can’t get the WiFi to connect 🙁
