Xorg 1.6 and xrandr 1.3 dual monitor problems

First my setup:

lspci output:

 ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]

xrandr output:

Screen 0: minimum 320 x 200, current 2975 x 1680, maximum 3000 x 1700
DVI-1 connected 1050x1680+0+0 left (normal left inverted right x axis y axis) 434mm x 270mm
   1680x1050      59.9*+
   1280x1024      75.0     60.0  
   1152x864       75.0  
   1024x768       75.0     60.0  
   800x600        75.0     60.3  
   640x480        75.0     59.9  
   720x400        70.1  
DVI-0 connected 1920x1200+1055+0 (normal left inverted right x axis y axis) 519mm x 324mm
   1920x1200      60.0*+
   1600x1200      60.0  
   1680x1050      59.9  
   1280x1024      75.0     60.0  
   1152x864       75.0  
   1024x768       75.0     60.0  
   800x600        75.0     60.3

xorg "virtual screen"

Virtual 3000 1700

My Left Monitor is DVI-1
My Right Monitor is DVI-0
I like to have a portrait view on my left monitor and a landscape view on my right monitor.

Previously I used to run this script to arrange my monitors:

xrandr --ouput DVI-0 --mode 1920x1200 --pos 1080x0 --rotate normal --output DVI-1 --mode 1680x1050 --pos 0x0 --rotate left

After I updated to xorg 1.6 and randr 1.3 my settings were screwed up. Badly.
So I disabled my monitor script and started to experiment.

4 hours later ....

I was getting so frustrated that I was seriously considering moving to crunchbang. But I stuck with it.

Finally I figured out that I cannot call all of the commands that I want at one time.

What I mean is this works:

xrandr --output DVI-0 --rotate normal --mode 1920x1200
xrandr --output DVI-1 --rotate left --pos 0x0
xrandr --output DVI-0 --pos 1055x0

This does not work:

xrandr --output DVI-0 --rotate normal --mode 1920x1200 --pos 1055x0 --output DVI-1 --rotate left --pos 0x0

Was this a bug in randr 1.2 or is it a regression in randr 1.3?

For a few hours a month, you can adopt an orphaned package

Interesting .... ಠ_ರೃ
