Note:
If you plan to use X11 for extended periods of time, it is highly recommended you get a two button mouse. It will make using Linux and X11 much easier, as the right mouse button is used extensively in Linux. Plus, you can get a good mouse for about 20 bucks, in places like your local Staples or CompUSA. They are not as nice as the Apple Pro Optical Mouse, but they are better for using Linux with (you can hook this mouse up to any free USB port you have, so it means you won't have to forfit the Pro Mouse).
If you have an Old-World (Beige) PowerMac, then you should get an ADB two button mouse like the $20 MacAlley 2 Button Mouse, or the more expensive $50 Kensignton Orbit Trackball. Both work very well with PowerPC Linux.
If you have an New-World (Colorful) PowerMac, then you should get an USB two button mouse like the Logitech Wheel USB Mouse or the Kensignton USB Scroll Mouse-in-A-Box.
Mouse Emulation on New-World (Colorful) Macs
On all New-World Macs, the right click is automatically mapped to the Num. Lock (for Middle Click) and = (for Right Click) by Linux.
Note: This procedure works for before Xpmac and XFree86 users.
Mouse Emulation on Old-World (Beige) Macs
Old-World Biege PowerMacs, use ADB for Mouse and Keyboard. Linux doesn't automatically map a key to right and left mouse button.
Do this by using these kernel arguments: adbmouse=1,103,111
This makes F11 become the middle click, and F12 the right click.
Place that kernel argument in /etc/quik.conf as:
append="adbmouse=1,103,111"
BootX users should put adbmouse=1,103,111 in the More Kernel Arguments box in BootX.
Note: This procedure works for before Xpmac and XFree86 users.
