Well, glxgears is a graphical application and needs $DISPLAY. I would not expect that to work without -d. So I guess I should have been more specific. I was thinking more along the lines of simple commands. Something that would test if my wild guess of something to do with LD_LIBRARY_PATH or other was the problem. Something like this. dchroot -c ia32 hostname dchroot -c ia32 pwd dchroot -c ia32 ls That type of thing. Bob -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

As root it's working too. Have all of your 'dchroot' calls used -d? Does it work without -d? The above makes me think you have LD_LIBRARY_PATH or some such variable set which is breaking bash in the chroot. The -d is preserving the environment. By going in as root and then switching to the user you are probably avoiding passing along those environment variables. So I would try it without the -d and then I would check the environment.

Hm no, now it does not say "no shell" anymore but: $ dchroot -c ia32 -d glxgears (ia32) glxgears dchroot: chroot: Operation not permitted dchroot: Child exited non-zero. dchroot: Operation failed.

The shell (/bin/bash) > exists and is readable and executable for everyone. Use dchroot as root to become root in the chroot. Then from there can you su to the user? sudo dchroot -c ia32 At that point you should be root in your chroot. Use su to load the user environment. Where 'youruser' is your normal user account. su - youruser What does that say? I am guessing it will say no shell. Look to see why. These commands should help. id youruser getent passwd youruser grep youruser /etc/passwd grep youruser /etc/group Somewhere along the way the problem will be obvious.
