X questions (SGX Xorg)

Recommended Posts

I got the SGX xorg working nicely. It supports the 3D GPU on the beagleboard X15. I got it to work on both Beagleboard X15 Rev A2 and Rev C.

I plan to do the same with the beaglebone in a few weeks.

 

I create the DRM driver for the kernel and the GLES and EGL libraries

Now I want to get mate to work with it but have some issue which don't seem to have an easy solution.

I started with this command :

 emerge -auDN @world

It lists a lot of app and at the end this :

The following mask changes are necessary to proceed:
 (see "package.unmask" in the portage(5) man page for more details)

I do not want either mesa or xorg to be installed since they would conflict with what I have.

SGX also has custom mesa files

Any idea how to get around this issue?

 

I think it should be fairly straightforward to get the desktop started by changing the configuration for xinit (startx)

How do we get lightdm to play the right way with my xorg?

Here is the script to start xorg from Texas Instruments :

The script is on /etc/init.d/xorg

#!/bin/sh

x_start()
{

        # Start the X Server.
        #
        /usr/local/XSGX/bin/X -config /usr/local/XSGX/etc/xorg.conf > /dev/null 2>&1 &

        echo "Starting Xorg"
        return 0;
}

x_stop()
{

        # Stop the X Server.
        #
        [ -f /tmp/.X0-lock ] && read XPID < /tmp/.X0-lock && [ -n "$XPID" ] && kill $XPID && while [ -e /proc/$XPID ] ; do sleep 1; don

        echo "Stopping Xorg"
        return 0;
}


# Deal with the type of invocation we get.
#
case "$1" in
start)
        x_start
        ;;
stop)
    x_stop
        ;;
*)
        echo "$0: unknown argument $1." >&2;
        ;;
esac
