Hi, The idea to introduce this acpi change in the software updates across linux platforms, I think was a very bad.
It has meant that either I can't login or I am staring at a purple, or black blank screen depending on the linux flavour. or the system is hanging and won't turn off. Anyway I am currently able to login , but when I log off I have a black screen but the laptop doesn't actually power off. I would appreciate if some one can tell me the precise kernel parameter values so the laptop will turm off and I promise to turn off software updates after that.
