After running Linux on my iBook G3 (800MHz) for 4 years, I've finally got fed up with the increasing amount of bugs that keep appearing in Linux. This weekend I backed up everything and installed OpenBSD 4.0. So far, I'm very happy indeed. I'm a GNOME fan and well aware that there is not a recent version on GNOME so I've reverted back to fluxbox that I happily used several years ago. The benefit of doing this is that it is much more responsive within Xorg. Something that's very welcome with a laptop of this age. It will keep me going another couple of years anyway, should the hardware last that long!

It also means I can create macppc binpatches now aswell as i386 ones.

The soundcard is not supported, but that's not a problem. Also it does not suspend but this has always been hit and miss with Linux anyway.

I've figured out how to set the F10 and F11 keys as middle and right click like I had under linux too (and fix backspace!). I use the following .xmodmap file:


keycode 107 = BackSpace
keycode 75 = Pointer_EnableKeys
keycode 76 = Pointer_Button2
keycode 95 = Pointer_Button3


I need to press F9 first to activate these keys. Not sure if there is a way around this, but not great problem.

Here's the dmesg for anyone who cares:

I ran OpenBSD for a while on a Bondi Blue iMac (original 233Mhz for those who don't know). It worked pretty good on the side of my desk. I loaded up fluxbox and a few terminals an it worked great. Sure, it's no speed demon but it would even run firefox for those times links -g didn't cut it.

It gave life to an old machine that wasn't good for much else. I'm sure an 800Mhz iBook will be good for a while longer. :biggrin:
