hello shep,

not easy to read the xrandr datasheet, I check the version: it's 1.4.
here is the description


Code:
RandR version 1.4 options
       Options for RandR 1.4 are used as a superset of the options  for  RandR
       1.3.

       --listproviders
              Report information about the providers available.

       --setprovideroutputsource provider source
              Set  source as the source of display output images for provider.
              This is only possible if source and  provider  have  the  Source
              Output and Sink Output capabilities, respectively.  If source is
              0x0, then provider  is  disconnected  from  its  current  output
              source.

       --setprovideroffloadsink provider sink
              Set  provider as a render offload device for sink.  This is only
              possible if provider and sink have the Source Offload  and  Sink
              Offload  capabilities,  respectively.   If  sink  is  0x0,  then
              provider is disconnected from its current render offload sink.
how to set the right parameters, it is necessary that the server X stops using VESA and use ATI radeon, more options with my two video cards and my two output screen, I do not know how!
in your link there are no examples of using xrandr!

Code:
hpc-raptor# xrandr -v
xrandr program version       1.4.0
Can't open display 
hpc-raptor#
Whenever I try an option I have this message "Can not open display" even when I kill the X server. Here is my account!
Code:
hpc-raptor$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024      0.00* 
   1024x768       0.00  
   800x600        0.00  
   640x480        0.00  
hpc-raptor$
more the firefox that I compile with / usr / pkgsrc / www stops working on youtube.

Kind Regards
Philippe
