Re: xorg X11 xorg.conf does not support 'Virtual' parameter

[Dan Sawyer <dansawyer@xxxxxxxxxxxxx>]

Thanks for the note. The major difference (except for the dropped mode lines messages) in the log files is the system that doesn't work has the following lines:

enable montype: 2
(II) RADEON(0): I2C device "VGA_DDC:ddc2" registered at address 0xA0.
(II) RADEON(0): I2C device "VGA_DDC:ddc2" removed.
(II) RADEON(0): I2C device "VGA_DDC:ddc2" registered at address 0xA0.
(II) RADEON(0): I2C device "VGA_DDC:ddc2" removed.

(II) RADEON(0): DDC Type: 2, Detected Monitor Type: 0
(II) RADEON(0): Detected Monitor Type: 0
(II) RADEON(0): EDID for output DVI-0
(WW) RADEON(0): DDC2/I2C is not properly initialized

The kernel is a custom kernel and is identical for both systems. Do you get DDC2/I2C errors?

With Fedora 8 the Virtual parameter in xorg.conf is no longer honored. 
The exact xorg.conf has worked correctly for many  releases. Below is a 
snippet from xorg.conf:
    

I am using the "virtual" parameter in my xorg.conf file and it seems to
be working as expected. Xorg.0.log shows that some mode lines were dropped
because of it.

  

Section "Screen"
       Identifier "Screen0"
       Device     "Videocard0"
       Monitor    "Monitor0"
       DefaultDepth     16
       SubSection "Display"
               Viewport   0 0
               Virtual   1600 1200
               Depth     16
               Modes    "1024x768" "800x600" "640x480"
       EndSubSection
EndSection
