Checking that things are working

To verify that the kernel DRM modules are loaded and functional, run the following command:

dmesg | grep -e agp -e drm

This should produce output similar to this:

    Linux agpgart interface v0.102
    agpgart: Detected VIA KM400/KM400A chipset
    agpgart: AGP aperture is 64M @ 0xe0000000
    [drm] Initialized drm 1.1.0 20060810
    [drm] Initialized via 2.11.1 20070202 on minor 0
    [drm] Used old pci detect: framebuffer loaded
    agpgart: Found an AGP 3.5 compliant device at 0000:00:00.0.
    agpgart: Device is in legacy mode, falling back to 2.x
    agpgart: Putting AGP V2 device at 0000:00:00.0 into 4x mode
    agpgart: Putting AGP V2 device at 0000:01:00.0 into 4x mode

To verify that the openchrome driver is being used, run:

grep openchrome /var/log/Xorg.0.log

This should produce the following output:

    (II) LoadModule: "openchrome"
    (II) Loading /usr/lib/xorg/modules/drivers//openchrome_drv.so
    (II) Module openchrome: vendor="http://openchrome.org/"
    (!!) For support, refer to http://openchrome.org/.

To verify whether direct rendering is working (just in theory, as on some chipsets it doesn't actually work), run:

grep rendering /var/log/Xorg.0.log

On the older chipsets this should say:

    (II) CHROME(0): direct rendering enabled

To verify whether there are any errors:

grep "^(EE)" /var/log/Xorg.0.log

To verify whether there are any warnings:

grep "^(WW)" /var/log/Xorg.0.log
