chroot to run hd-installed distro's programs from chroot in live distro?
I would like to use unique programs from a hard-drive installed distro, while booted in a live-CD distro or another hard-drive installed distro.
I've tried doing this with chroot:
-booting into the live-CD,
-mount the root partition for a HDD-installed distro,
-open terminal as root,
-type in command "chroot /mnt/hdd-distro",
-type in command "thunderbird"
...Any terminal-only program is fine, but with any such graphical program, it fails to run with an error, "(thunderbird-bin:19847): Gtk-WARNING **: cannot open display:".
