- May 4, 2001Brian,
Mouse: no idea about this. For me, I have an external PS/2 keyboard
and USB mouse so I haven't run into any problems. Actually, I do have
a PS/2 mouse, but that's used with the docking station/port replicator
which has both a mouse port and a keyboard port so no splitter is needed.
Monitor: with XFree86 4.0.3, you should be able to define the external
frequency you want. For example, I use:
VendorName "Monitor Vendor"
ModelName "Monitor Model"
# Option "DPMS"
Modeline "1400x1050" 159.0 1400 1464 1784 1912 1050 1052 1064
1098 -HSync -VSync
This is 76Kz. You also need the device option:
What this does for me is if the monitor is attached, it will boot on
it with a refresh of 76Hz. If no external monitor is attached, it
uses the LCD. If I want symultanious mode, I boot with the monitor
and hit Fn-F8 to cycle, but this results in the monitor at 60Hz. This
is fine by me as a rarely use symul mode. When I'm at my desk, I want
the monitor only.
I can post my entire config if needed.
