Thanks Kustom42 and bigrigdriver.
The information provided by you guys was useful, thanks a lot
But, what I am wanting is all the messgaes that appear during boot-up. For example, during the limited time I had as the mesages flied by during bootup, I could see messages like "Starting NetworkManager dameon"; "Starting avahi daemon", etc. etc.
But I could not find these messages anywhere in "dmesg", or "/var/log/messages".
Any way we could get ALL the messages?
