Screen resolution setting with YDL on G3, help needed

[chevy]

Hi,

I installed Yellow Dog Linux on my B&W G3. Looks fine but I go a few problems. The first one is that the system does not propose to set the monitor to its original resolution (1280x960) and remains with 1024x798 or lower. Do you know where I can correct that ?

My video card is a Radeon 7000 Mac Edition and the monitor is a SyncMaster 172T, both can go higher res as this is what I do on MacOS-X. YDL doesn't know this syncmaster, but I told him I have an Apple 17" LCD that can support the same signal.

Here is a dump of the /etc/X11/XF86Config

Section "Device"
 
        #BusID
        Identifier  "ATI Radeon VE"
        Driver      "radeon"
        VendorName  "ATI Radeon VE"
        BoardName   "ATI Radeon VE"
        Option      "UseFBDev" "true"
EndSection
 
Section "Screen"
        Identifier "Screen0"
        Device     "ATI Radeon VE"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Depth     16
                Modes    "1024x768" "832x624" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Depth     24
                Modes    "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

Ok, I did it !!!

1) select generic display and copy min-max frequencies of my display
2) edit (using root) /etc/X11/XF86Config and add "1280x1024" in front of the other screen sizes

And it's done
