Re: Touchpad not working on PowerBook G4 12"

Not sure if this situation even shares any code with x86, but if you're 
getting mouse function in a VT but not X11:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251149

Another possibility is software cursor, which I usually use to dodge 
regressions that occasionally come with xorg updates.

FreeBSD coral.acadix  bacon ~ 1003: more 
/etc/X11/xorg.conf.d/20-swcursor.conf
Section "Device"
     Identifier "Device0"
     Option "SWCursor" "on"
EndSection

I'd be interested in some feedback on sysutils/desktop-installer on the 
g4.  I've tested it on an iMac G5 and a PowerMac G5.

Regards,
