You need entries in /dev. You can either rbind mount the real /dev to
the chroot /dev, or just copy files there. The rbind mount is nice.

Make sure /etc/hosts contains a valid entry for the machine or some
things will fail.

Another posibility is that the kernel on the host system isn't capable
of running your X server. Not sure if it needs framebuffer support or
anything else. I have never run X on an arm myself.

yes, we have binded dev,proc,and sys folder to the chroot and its seems everything fine with the framebuffer sitting in the /dev/fb0, its working well with some other qt related application wih -qws(quick window system).Only we have issue in configuring Xorg.conf file with resolution and frequency.

As your telling Xserver will do anything with /etc/host file, yes we have created the host name in the hosts and setted the DISPLAY environment variable to the localhost

#export DISPLAY=:0.0 ---- also tried with many other options.

If framebuffer is working fine with other application means, then i dont think any problem in the kernel. Also we are not trying to run in the host, its in the arm platform itself. we didnt even get the terminal window in the vga output from our target. Show me some light in this.
