Comment 13 for bug 1325881

so, finally i was able to test the newest upstream-kernel (v3.16-rc1-utopic) & with this, everything went worse. i wasn't able to enter the login-screen. all i saw, was just a neverending report of some "psmouse serio4 error" & some usb-port (o.s.) "not suspendend yet" message.
think i'll try now the previous kernel (v3.15.1-utopic), to examine, if then i'll be able to enter the start-screen.
