Can I chroot from MX23 Linux to Xubuntu 24.04 and run gui programs?

Yes, you can chroot from MX23 Linux to Xubuntu 24.04 and run GUI programs, but some steps are necessary to enable GUI support inside the chroot environment.

Key points to enable GUI programs in a chroot are:

  • Bind mount the host system's X11 Unix socket directory (/tmp/.X11-unix) into the chroot to allow GUI programs inside the chroot to communicate with the host's X server.
  • Permit connections from the chroot user to the X server using xhost +local: on the host.
  • Set the DISPLAY environment variable inside the chroot (e.g., export DISPLAY=:0) prior to running GUI applications.
  • Bind mount or provide access to other essential file system paths like /proc, /dev, and /tmp inside the chroot if needed for full operation.

This allows GUI applications installed in the Xubuntu 24.04 chroot to display on the MX23 host system's X server. It is a common approach and works securely if you carefully control X server access.

Summarized steps example:

  1. On MX23 host: 
    xhost +local:
sudo mount --bind /tmp/.X11-unix /path/to/xubuntu-chroot/tmp/.X11-unix
sudo mount --bind /proc /path/to/xubuntu-chroot/proc
sudo mount --bind /dev /path/to/xubuntu-chroot/dev
sudo mount --bind /tmp /path/to/xubuntu-chroot/tmp
  2. Chroot into Xubuntu 24.04: 
    sudo chroot /path/to/xubuntu-chroot /bin/bash
export DISPLAY=:0
  3. Run GUI apps, e.g., gedit or xterm.

This setup lets GUI apps in the chroot run seamlessly on the MX23 system's display.reddit+2​

Note: Wayland requires additional handling and may not work as easily; this is primarily for X11-based GUI. Also, some apps may need additional libraries or user permissions configured inside the chroot.
