As Bruce said, the Twin Turbo doesn't work with X. As to Linux have you tried having Xorg configure itself? If it isn't running a shell after boot you need to put a "1" in as kernel parameter to force it into a shell. Get the man page for Xorg and look for the command line argument to self configure it. Then run Xorg with that argument. If that doesn't do it then you will need to create or modify the Xorg configuration file. A web search on this will give you a lot of help (that's how I did it). -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting "I'm a designated driver on the Information Super Highway" --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
