First of all, let me congrats the admins for a great forum!
Now for the case...
When I boot my Ubuntu on my Asus A6000 A6km laptop with a USB device connected (my mouse is USB connected), the OS freezes at "Starting up ...". Ok.. when I disconnect my mouse, the booting is ok, and everything is ready to go. Then I can connect my mouse when the login screen is showing.
Any ideas for what this can be? Is is possible to see what is going on during the boot? I used Mandriva before, and I could see if anything was "OK" or "Failed".
