           Summary: Monitor refresh rate not set correctly
           Product: xorg
           Version: 7.4
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: trupf1 at gmx.de
         QAContact: xorg-team at lists.x.org


If I start xserver with resolution 1280x1024 I get now a refresh rate of 60 Hz,
where with the old version it was 75 Hz. DDC is switched of in my config, and
it specifies: 
Section "Monitor"
...
DisplaySize  340        270
HorizSync    30.0 - 80.0
VertRefresh  56.0 - 75.0
#VertRefresh  56.0 - 75.03
EndSection

This was (and still is) working with version 7.3. If I use the second
VertRefresh I initially get 75 Hz, but if resolution is switched forth and back
(e.g. through starting a game with less resolution, or via key combination
CTRL-ALT-"+" and CTRL-ALT-"-"), then it goes back to 60Hz. Further more I get a
kind of flickering while switching resolution or even starting a wine
application, which was not the case before.
