Im using debian lenny on my desktop without eny problem.
I did installed debian in my notebook too.
but my wireless device in not working properly, not detected.
and also when i play a video file oe a movie it plays withou any problem until i change the screen size to full, it does not play on full screen smoothly, even though the driver is installed?

it is a hp compaq 610


graphics- Intel GMA X3100 Dynamic Video Memory Technology 4.0
wireless- Intel PRO/Wireless 3945ABG

I heard that Suse is better than any os on notebooks?
is that true?
or what is more suit for a notebook or hp compaq 610 ?

Rather than switching distros, fix the problems you are having. take the time to know how things work.

http://wiki.debian.org/WiFi You probably just need the firmware for your wireless.

By video do you mean a flash video in your browser? Older versions of flash and iceweasel have problems, upgrade to the versions in the backports.org repo. Also you might want to Google your video card to get the best xorg.conf, there are various things you can do to tweak it.

the trick is to use the "live-cd" to 'test' all of the components,
to see if they all work, before installing the O/S onto the hdd.

Debian does not provide non-free firmware in any live-cd.

IMHO, debian is without any doubts one of the very best/easy distributions for laptops.
The laptop meta package does most things.
Just add your non-free stuff as craigevil said.

finally wireless started to work, i had to install the driver

but my video is not much good.
if i play a movie not only a one on youtube, any movie file, it will play well until i switched to full-screen mode.
if i switched to fullscreen mode, it does not play smoothly. may be i need to install a nonfree driver.

any one know where to find a Mobile Intel PM965 driver or Intel GMA X3100

actually this video problem occurs only if i enable compiz settings

Does it work if you're using the X11 driver with mplayer:
Depending on your hardware and X11(xorg) version it might help if you change your video accelerator (Option "AccelMethod" in xorg.conf).
