Re: Lucid (10.04) wont shutdown my computer
Have you updated your bios to the latest version?
Give that a try. Mine was giving me a few acpi and apm hiccups.
It solved a suspend/resume problem which may be related to this.
You will need to change the bios boot order to make sure the cd/dvd drive boots with an Ubuntu CD in it. Apart from that try it with the default settings.
I had the same shutdown problem and could not find a solution - ended up doing a fresh install. It's ok now.
Also have you checked your install cd with md5sum?
A vivid and creative mind characterizes you.
