laptop lid and tty issue on latitude

[Jason Schaefer]

I have a dell latitude d505 and since I installed ubuntu studio when I
close the laptop lid the screen goes blank except for the mouse which
freezes and I can't get to any tty's. I have to hold the pwr button to
shutdown. Also, when I switch tty's the screen blanks and I can only
sometimes get back to tty7.

I have run regular ubuntu on this machine, including gutsy. I have not
experienced anything like this since debian in 2005.

Thanks
Jason
