Comment 43 applies to use of xorg.conf in attempting to produce desired
X configuration, e.g. xorg.conf for Intel gfx containing:
Section "Device"
Identifier "Default Device"
Option "monitor-VGA1" "Default Monitor"
EndSection
Section "Monitor"
Identifier "Default Monitor"
Option "DPMS" "off"
DisplaySize 405 253 # 120 DPI @ 1920x1200 & virtual
Option "PreferredMode" "1440x900"
Option "Panning" "1920x1200"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "Default Device"
Monitor "Default Monitor"
EndSection
produces expected results for server 1.9.3, but not for server
1.16.0RC1. Functional panning matching that produced by the above
xorg.conf can be at least mostly achieved in i915 via xrandr as follows:
xrandr --dpi 120 --fb 1920x1200 --output VGA1 --mode 1440x900 --panning
1920x1200
or
xrandr --fbmm 405x253 --fb 1920x1200 --output VGA1 --mode 1440x900 --panning
1920x1200
A remaining problem therefore exists that did not exist prior to the
server changes made that made this bug report necessary in the first
place, that xorg.conf no longer does what xrandr can, as xorg.conf used
to be able to do. This is new with the 96204 patch, as with the 56408
patch and server 1.12.3, xorg.conf gets the job done as expected.
