Configuring X Windows

5.2 Configuring X Windows

On most PPC system we use the XF68_FBDev. Unlike previous X servers this one requires more setup. First you will need to run the Xconfigurator program (this is done in the installer.) The Xconfigurator should get X up and running, however you may wish to further customize it. One way is to use the fbset program.

First put your monitor into the resolution you want:

fbset -xres 1024 -yres 768 -depth 32

Next to get a custom modeline for X:

fbset -x

You will get output such as:

Mode "name"
    # D: 106.735 MHz, H: 75.378 kHz, V: 93.289 Hz
    DotClock 106.736
    HTimings 1024 1056 1192 1416
    VTimings 768 772 776 808
    Flags    "-HSync" "-VSync"

That information should be copied into the /etc/X11/XF86Config file. It should be placed under the comment about the Apple Power G3.

Next scroll down further until you see something similar to:

Section "Screen"
    Driver      "fbdev"
    Device      "control"
    Monitor     "Apple Multiple Scan 15 Display"
    Subsection "Display"
        Depth       8
        Modes       "832x624"
        ViewPort    0 0
        Virtual     832 624

Change the "832x768" line to "name" and the Virtual 832 624 to Virtual 1024 768. Save your changes and run X.
