Hi,
I own a PowerBook G4 and I do not succeed in using the 2nd monitor after
using these steps (I am not an Xorg specialist):
1. Add Option ... in xorg.conf
2. Restart computer and enter X
3. snoopy:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1280 x 854, maximum 1280 x 1280
LVDS connected 1280x854+0+0 (normal left inverted right x axis y axis)
0mm x 0mm
1280x854 60.0*+
1280x800 60.0
1280x768 60.0
1024x768 60.0
800x600 60.3
640x480 59.9
VGA-0 disconnected (normal left inverted right x axis y axis)
S-video disconnected 800x600+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
4. Connect the 2nd monitor (DVI cable)
5. [the 2nd monitor prints: "No signal" and remains completely black]
6. snoopy:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1280 x 854, maximum 1280 x 1280

axis) 0mm x 0mm
7. snoopy:~$ xrandr --output LVDS --mode 1024x768
8. [the laptop screen changes resolution to 1024x768, but nothing
happens on the 2nd monitor]
9. snoopy:~$ xrandr --output VGA-0 --mode 1024x768
xrandr: cannot find crtc for output VGA-0

[Nothing happens on the 2nd monitor...]
- How to put the 2nd monitor in clone mode?
- Why both VGA-0 and S-video were connected, afterwards only VGA-0?
- Why LDVS is 0mm x 0mm?
