How To Chroot and Xnest

In the example I will be using Lmde which I reviewed the update process to update pack 7. I will be ‘chrooting’ into Debian linux. I have mounted the Debian partition to /mnt/debian .

As you can see it is not without error , I’ve had Xnest close when trying run gui programs and as you can see in the above XrandR and errors regarding theming.
