Re: 2nd monitor output

[peter plessas <plessas@mur.at>]

Dear List,

i made some progress in the externl VGA-out problem, but one thing 
remains unclear:

ok, i have an
ATI Technologies Inc Rage Mobility M3 AGP 2x (rev 02)

and using the m3mirror tool i can get an external vga monitor to display 
the open firmware startup message:

... ok
copying OF device tree...done
Calling quiesce ...
returning 0x1400000 from prom_init

Then i i tried to pass the kernel boot arguments: 
video=aty128fb::crt:1.lcd:1

and got on LCD: flickering screen
on external CRT: still only OF boot msg.

LCD and CRT are both at 1024x768

Dunno if i got this right: to mirror an X screen i need to change my 
XConfig file, right?

I don't really need a console on the external CRT.

thanks for the help!

Peter P.
