In general, you would be better off with a current desktop version of
Linux, like Ubuntu or Fedora, than a server version of Linux, like
RHEL. The software graphics drivers in the server editions are
conservatively updated and are often buggy for 3D graphics. As Tom
said, you need to install the graphics driver from the card's vendor.
If you have Intel graphics, my condolences -- you can try the newest
version of Linux you can find, but you would be better off replacing the
laptop with one that has AMD/ATI or NVIDIA graphics, and if it's a
desktop, putting in an AMD/ATI or NVIDIA graphics card. In a similar
vein, if your graphics card is ancient and not recognized, then maybe
it's time to spend $20-$50 for a newer card :-)
