Getting OpenMoko working on host with Xephyr
From Openmoko
The goal of this page is to show you how to run an OpenMoko development image on your host x86 development machine in a chrooted environment.

Build an image
First, you should use Building OpenMoko using the MokoMakefile to build an openmoko-devel-image for your host architecture (x86 in our case). Make sure you put the moko makefile in /home/moko/Makefile .
Prior to that, edit your build/conf/local.conf to make it look like this:
MACHINE = "qemux86" DISTRO = "openmoko" BUILD_ARCH = "i686" INHERIT += " devshell" SRCDATE_eds-dbus = "now"
Once you have built the image, you can start working toward running the image.
Setup the image filesystem
The filesystem of the image can be found at /home/moko/build/tmp/rootfs . It is that image that we want to run in a chrooted environment.
We will copy that that rootfs directory somewhere so that subsquent builds (using the MokoMakefile for instance) don't overwrite it.
Make sure you have root privileges:
su -
Copy the rootf into a directory called MokoBox. From now on, we will call the chrooted environment a MokoBox.
cp -r /home/moko/build/tmp/rootfs /home/moko/mokobox
make sure /dev and /proc of the host machine are visible from within mokobox
mount --bind /dev /homo/moko/mokobox/dev mount -t proc none /home/moko/mokobox/proc
start the mokobox
chroot /homo/moko/mokobox /bin/sh
In chroot'ed environment
set environment variables
DISPLAY=:1 LANG=C HOME=/home/root export DISPLAY LANG HOME
Create pango.modules file
pango-querymodules > /etc/pango/pango.modules
Create gdk-pixbuf.loaders file
gdk-pixbuf-query-loaders > /etc/gtk-2.0/gdk-pixbuf.loaders
Remove touch screen calibrator. Since touch screen hardware is not present, the touch screen calibration prevents X start-up on PC.
rm /etc/X11/Xsession.d/30xTs_Calibrate
Start nested X server
In another terminal (not related to mokobox), start Xephyr
Xephyr :1 -ac -2button -host-cursor -screen 480x640
You should see the window of Xephyr now.
Now, back in the mokobox, start an X Session:
/etc/X11/Xsession
You should see OpenMoko booting in the Xephyr window.
