[PlanetCCRMA] New xorg plus ATI resolution problem

[Jamie Bullock]

Hi,

I've just updated to the latest xorg(6.8.2) for FC3 from the repository.
I am running 2.6.10-2.1.ll.rhfc3.ccrma kernel. The updates went
smoothly, so I thought I would take a risk and install the latest ATI
drivers (actually for 6.8.16).

The drivers work, that is the kernel module compiles and loads
correctly, and DRI/3D performance works fine. The problem I have is that
I can't go beyond a resolution of 1024x768. My laptop uses 1280x800, so
the lower res looks poor.

Has anyone else experienced this, or similar, or have any suggestions?
Otherwise, take this as a warning!

The relevant lines in my xorg.conf are:

Section "Monitor"
    Identifier   "Monitor0"
    VendorName   "Monitor Vendor"
    ModelName    "LCD Panel 1280x800"
    HorizSync    31.5 - 90.0
    VertRefresh  60.0 - 60.0
    Option      "dpms"
Endsection

Section "Device"
    Identifier  "Videocard0"
    Driver      "fglrx"
    VendorName  "Videocard vendor"
    BoardName   "ATI Radeon Mobility 7500"
    Option      "NoDCC"
    Option      "VideoOverlay" "on"
    Option      "no_accel"  "no"
        Option      "no_dri"   "no"
        Option      "mtrr"    "off"

EndSection

Section "Screen"
    Identifier "Screen0"
    Device     "Videocard0"
    Monitor    "Monitor0"
    DefaultDepth     24
    SubSection "Display"
        Viewport   0 0
        Depth     24
        Modes     "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
EndSection


Thanks!
