Yes. If not you lose OpenGL. > 2.

It updates at approximately 2 hz. With ati-drivers and ati's OpenGL, the game runs fine. This is on a radeon mobility 9000, so your mileage certainly may vary. > 4.

You might need to set # opengl-update xorg-x11 to use X.org's opengl interface (if you have the system running for a while with the ati-drivers installed, it is most likely already running ati's opengl) And you probably would need to modify your xorg.conf to reflect the change. -- ---------------------------------------------------------------- * Address: 45 Spelman Hall, Princeton University 08544 * * Phone: x68958 AIM: AngularJerk * * E-mail: [EMAIL PROTECTED] From: sep.dynalias.net * ---------------------------------------------------------------- "`How do you feel?' he asked him. `Like a military academy,' said Arthur, `bits of me keep passing out.'" .... `We're safe,' he said. `Oh good,' said Arthur. `We're in a small galley cabin,' said Ford, `in one of the spaceships of the Vogon Constructor Fleet.' `Ah,' said Arthur, `this is obviously some strange usage of the word "safe" that I wasn't previously aware of.' - Arthur after his first ever teleport ride.
