I recently bought a cheap Samsung NP-R540 with an ATI Mobility Radeon HD 4500.
Ubuntu 10.10 installed smoothly. I encountered two problems:
- The comercial ATI-video driver did not want to install, so I switched to
the free driver and I’m happy since. - The Touchpad does not work well for me in multitouch-mode.

Network
Both ethernet and wifi worked out of the box.
3D Acceleration
I first downloaded the commercial ATI driver from http://www2.ati.com/drivers/linux/ati-driver-installer-11-2-x86.x86_64.run
And tried to install with:
sudo ./ati-driver-installer-10-9-x86.x86_64.run --listpkg sudo ./ati-driver-installer-10-9-x86.x86_64.run --buildpkg Ubuntu/maverick ls fglrx* sudo dpkg -i fglrx*
But this failed with some compilation error. So I decided to use the free driver (instructions here and here):
sudo /usr/share/ati/fglrx-uninstall.sh # (if it exists) sudo apt-get remove --purge fglrx* sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon sudo apt-get install xserver-xorg-video-ati sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core sudo dpkg-reconfigure xserver-xorg
The free driver works well for my needs (a bit of 3D visualisation and Tuxracer now and then).
Multimedia
Sound, microphone and webcam worked out of the box (don’t forget to unmute your mic if you try it!).
Touchpad
The touchpad gives me the most headaches. In normal mode it works just fine but it does not offer a scrollbar on the right. In (Gnome) System/Preferences/Mouse/Touchpad I enabled two finger scrolling, but the experience is not satisfying.
