    Debian PPC won't run X


    I've just installed Debian to an old-ish iMac. It was working, but since I downloaded and installed the graphical desktop, it boots up to a black screen. I'm using kdm, if that makes any difference. Other than that, I have no clue about what's installed or how it's configured.

    kill the xserver with ctl-alt-f1, login as root to a terminal, and kill kdm with
    /etc/init.d/kdm stop...

    check out you monitor and screen settings in /etc/X11/XF86Config-4...is anything out of place? Check your monitor's vertical and horizontal sync ranges, this causes quite a bit of problems, and the debian installer is not great at setting these up correctly...yoiu may want to also chekc out your video drivers...

    I looked at XF86Config-4, and nothing looked obviously wrong to me, besides really narrow hsync and vsync ranges. I backed it up and ran XF86Config to make a new one. It generates a fatal "no screens found" error when I start up X. Here are the relevant sections from my new XF86Config-4 file:
    Code:
    Section "Monitor
       Identifier "iMac Nokia 447Xi"
       HorizSync 31-91
       VertRefresh 50-100
    EndSection
    
    Section "Device"
       Identifier "ATI Rage 128 Ultra"
       Driver "vga"
          #unsupported card
       #VideoRam 16384
    EndSection
    
    Section "Screen"
       Identifier "Screen 1"
       Device "ATI Rage 128 Ultra"
       Monitor "iMac Nokia 447Xi
       DefaultDepth 24
    
       Subsection "Display"
          Depth 24
          Modes "1024x768" "800x600" "640x480"
          ViewPort 0 0
       EndSubsection
    EndSection
    
    Section "ServerLayout"
       Identifier "Simple Layout"
       Screen "Screen 1"
       InputDevice "Mouse1" "CorePointer"
       InputDevice "Keyboard1" "CoreKeyboard"
    EndSection
    I'm a newbie, so this doesn't mean much to me. Maybe you can tell what's going on. Oh, and how would I go about making sure the video drivers are working right?

    Um, I just changed the Driver line from "vga" to "r128". Please don't laugh. It still doesn't work though. now the errors I get are

    Can't read V_BIOS
    No DFP detected
    then the server terminates with a "Caught signal 7" error.
    This is meaningless to me.
