Re: [gentoo-ppc-user] xorg.conf for Mac G4 mini

[David Friedlander <david@chezdavid.net>]

Hello, Joe,

The server doesn't start; stderr shows the following (captured with  
"xterm 2> test.log"
This is regardless of the setting of "UseFBDev"

Following this is the generated xorg.conf.  I see a strange "modeline"  
entry for 720x400 --
could that be the problem?  I believe that in the past I've deleted  
this and even tried to replace
it with a 1024x768 line, but truthfully I can't remember any more.

David

(I suspect the last 2 lines are generated when I press ctrl-c.)
