or because he specified so in the boot options. IIRC, otherwise it would not
boot at all.
The video chip, Leif, is definitely one of the RAGE LT series, aka Mach64,
like in all Wallstreet and Lombard PBs.
I guess the atyfb driver should certainly be in the default potato kernel?
So it might be a problem with the 12" Display, which has 600x800 resolution
unlike all other G3 series PBs. Specifying the resolution with vmode as a
boot parameter might help, though I can't remember which is the correct one
for 600x800 -- vmode=11, 12 or 13 might work (14 is 768x1024), but that should
not be too hard to find out. The LinuxPPC install manual, e.g. used to have
a listing of all available video modes.
You'll find a lot of useful info on Sergio's page
http://www.dcs.qmw.ac.uk/~sb/First-Aid/index.html
though this focuses, as most, also on the newer PBs with 14" active matrix
display.
I've found a modeline in my old XF86Config that *might* work for your
display:
# Apple PowerBook G3
Modeline "800x600" 100 800 816 824 840 600 616 624 640 -hsync -vsync
(put into Section "Monitor" for an XFree 3.3 config).
BTW, the Gnome will _never_ work without the X server running, so you'd
really need to get this fixed first. Gnome is rather one of the last things
I would try to get working, actually.
HTH,
Derek
