I've spent some time enabling my ATI Mobility Radeon X700 on my Acer 1694WLMi Laptop. It gave me some headaches, there was some problem with the official ATI, driver, fglrx, and mesa didn't want to go away. After some tries, I've decided to reinstall everything, xserver and fglrx, with the kernel restrictive modules. After that, I've just "sudo moddep -a" and rebooted. All went smooth, and I can now see:
tiagoboldt@Niath:~$ fglrxinfoThis means that my graphic card was already recognized and was ready to be user. So, what is a graphic card used for? GAMES, I've just installed the recently released second life client, savage for linux and a couple of games from the repositories, like Xmoto or Tremulous.
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON X700 Generic
OpenGL version string: 2.0.6011 (8.28.8)
Second life runs really good, but I don't see any point in playing that.. It can be freely downloaded here.
As for Savage, it's total fun, just spent the evening playing it. Worth a try!
