Comment # 12 on bug 954532 from Robin Roevens

Installed kernel from Leap on TW.
Now with acpi=off Xorg doesnt start up but also keeps trying starting up so I
don't get the chance to log into cli as the terminal constantly flickers back
to failing X.
and with acpi enabled, I get a black screen during boot and can't do anything
(SSH is not  enabled on the laptop)
I also can't boot in 4.3 anymore to disable Xorg since zypper removed that
kernel during install of 4.1.
How do I prevent X from starting in this state ?
