some (alot) of that is pretty confusing to me.
It seems to say running `xrandr' by itself will show the current mode.
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 4096 x 4096
VGA-1 disconnected (normal left inverted right x axis y axis)
DVI-I-1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 550mm x 340mm
1280x1024 75.0 60.0
1440x900 59.9*
1280x960 60.0
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
TV-1 disconnected (normal left inverted right x axis y axis)
so for me its 1440x900
so trying this:
sudo xrandr --output DVI-I-1 --mode 1440x900 --fb 2048x1536 \
--panning 2048x1536
And Yup, it worked. Only problem is that its barely any difference.
The monitor is a 25in with resolution of 1900x1280 so I gues 2048x1536
isn't enough bigger to be very noticable.
The panning is about 1/8 inch or less.
So I tried bigger:
sudo xrandr --output DVI-I-1 --mode 1440x900 --fb 4096x2700 --panning 4096x2700
Still no panning.
The cited url goes on and on about piles of stuff, but does not seem
to discuss what I'm trying to do.
I thought maybe the panning number has to be bigger than the fb
setting. But the few combos I tried failed:
sudo xrandr --output DVI-I-1 --mode 1440x900 --fb 2880x1800 --panning 4096x2700
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 150 (RANDR)

I'm not getting heads or tails from the web page... can you take an
educated guess what might work to give me a fair bit of panning room?
