Also, running Xconfigurator from the command line will allow you to
set up your X resolution if you're not using Xpmac (which ignores the
XF86Config file) - I'm using the accelerated FX68_FBDev server
mentioned in the "Blue G3 FAQ" at linucppc.org
Although if I use Xconfigurator, I need to readjust the keyboard and
mouse settings, manually, in XF86Config so my USB keyboard and mouse
are recognized by X in this G4. ( as noted on
http://people.a2000.nl/omoerbe/ ) Where does Xconfigurator keep
getting its defaults from for the XkbKeycodes, Xkbmodel, etc settings
when run so I can set them for mac settings? Maybe a lot of the
issues I'm having are corrected in LinuxPPC 2000 for the G4... ;)
OB MOL question -
I would love to be able to use a program called FB Lab, which uses a
hardware USB key ("dongle"). Currently my set up is CCD Camera
(hooked up to a microscope) (serial) -> Keyspan serial->USB converter
-> G4 (with hardware USB dongle on USB keyboard). This setup works
under MacOS, but under MOL, something is not getting recognized; -
but I can't tell from the error message - either the Dongle or the
camera through the Keyspan adapter. The program refuses to run
because of this (it needs the camera working, too) I'm guessing this
is probably a problem on the linux side of things, not passing along
info to the MOL. I'm going to try
http://www.qbik.ch/usb/devices/devices.php3 's driver to see if it's
the camera/keyspan side of things, but I'm not quite sure what to do
about the dongle. any suggestions?
