Laptop display stays on with lid closed

[Andrew Pantyukhin]

Hey!

I just wanted to thank you all for suggestions!

I ended up using Xorg's built-in features (option
"off time" "3" in section "serverflags"), so my
screen turns off after 3 minutes of inactivity.
Since closed lid implies inactivity in most cases,
I don't bother about it.

Interestingly, on my desktop (Radeon 9550 + NEC
LCD 1760NX) Xorg can only make screen go blank,
the backlight stays on. vbetool handles the issue
on Linux, but I couldn't port it yet.

Thanks!
