           Summary: Wrong video mode selected?
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: kronos.it at gmail.com
         QAContact: xorg-team at lists.x.org

The new radeon driver selects a video mode that's different from the one used
by the stable (i.e. 6.6.3). I reported the issue on the ML for driver version
6.7.192 ; I still see the same behaviour with 6.7.196-1 (Debian/experimental).
To recap, Xorg comes up with a video mode that's slightly different than the
one used by the previous driver (6.6.3). The result is that the image is not
centered on screen anymore (on the left I see a black stripe of 3-4mm, the
right part of the screen is cut).

New mode is:
"1280x1024"   108.00   1280 1328 1440 1688   1024 1025 1028 1066 +hsync +vsync
Old mode is:
"1280x1024"   135.00   1280 1296 1440 1688   1024 1025 1028 1066 +hsync +vsync

The big problem is that Windows also uses the "old" mode, hence I have to
adjust monitor settings each time I switch operating system...

I'm attacching the logs for both drivers.
