Compaq Presario 2100US & Ubuntu Linux

The Radeon Mobility graphics chipset in Compaq Presario 2100US notebooks seems to have some major quirks with the "ati" X video driver. I've finally managed to find a configuration that works perfectly and enables 3D graphics support. The configuration also works with the Beryl compositor. This is tested with Ubuntu Linux 7.04.

Here is the xorg.conf configuration file I am using.

Special Characters on Linux and UNIX Systems: The Compose Key

Have you ever wanted to spell jalapeño correctly but don't know how? Maybe you'd like to spell dæmon a little differently? What you want is the Compose Key!

The right hand meta key is often set as the Compose key. The meta keys often have a "Windows" logo on PC keyboards. UNIX system keyboards (e.g. Fujitsu Happy Hacking Keyboard) have a diamond symbol on the meta keys. Sun Type 5 keyboards also have a separate Compose key to the right of the right meta key. Compose works with all X11 applications.

MacOS X uses the right Alt/Option key as its Compose key for X11 applications. Non-X11 applications use dead key combinations unique to MacOS X and its predecessor NeXT. (See: Apple Technical Note 2056)
