I am getting no traction on xorg mail list - perhaps I cannot ask in a
way that makes them answer but the idea is...

Fedora 11 Beta (xrandr 1.3 - yeah!)

If I manually execute the command...
xrandr --output LVDS1 --mode 1024x600 --panning 1280x1024

I sort of get what I want...well, the background is tiled but my tiny
1024x600 screen becomes usable with panning and I can't understand why I
can't achieve this simply with xorg.conf.

Can anyone see what changes I need to make?
<snip>

I know very little about this but I was keeping an eye on it for my eeePC 701.

The changelog for Xorg 1.5.99 says:

Matthias Hopf (5):
     randr: Add monitor option "Panning" for initial panning configuration

So that says to me that somewhere in your Xorg.conf Monitor section
you should have a Panning keyword - which you don't have.

Looks like you'll have to dig around in Google though as I haven't
seen any easy source of information about it,
Or you could look at the code:
http://cgit.freedesktop.org/xorg/xserver/commit/?h=panning-for-server-1.6&id=44b89dc0a5aa23df69539754fb76c67c310530db

Looks to me like:

Section "Monitor"
<snip>
     Panning       1280x1024
EndSection

might do it...
----
death - death I say...

Parse error on line 44 of section Monitor in file /etc/X11/xorg.conf
       "Panning" is not a valid keyword in this section.
Have you tried:

Option "Panning" "1280x1024"

If you download the src.rpm for Xorg in F11b, Panning is definitely in
hw/xfree86/modes/xf86Crtc.c ... so it /should/ work...
----
Victory!

I now have virtual scrolling/panning on my 1024x600 screen to 1280x1024
whether or not an external display is connected to the VGA port.

thanks Sam - you inspired me to keep trying.

Turned out that it finally did work but what made it work was adding
back the second Monitor and Screen sections so I could have both my LVDS
and VGA screens and I gather that the larger size of the VGA is what
made it all work.

I have put this info on the Acer Aspire One page on Fedora Wiki for
anyone who is interested and it should provide a really good guide for
Sam's Asus eepro (obviously adjust for the built-in video and external
VGA display).

Oh - this is with Fedora-11-Beta (and current updates) because I believe
the xserver 1.6 and xrandr 1.3 versions are needed to make it work.

nice work craig!, good to see you finally got it working 8-)
