Comment 88 for bug 1700657

@Aswin Gigi (aswingigi): I also had the problem that the boot freezes when I try to start with 14.4-rc5 and I solved it by disabling secureboot in bios.

Now I can get ubuntu running with a working touchpad, but the wifi is not working at first: I dont't get any IP4 in my WiFi.

I had to connect a USB-wired LAN adapter once and that seems somehow to have fixed a misconfiguration somewhere. Now everything works fine: Touchpad and Internet.
