    I ran the command ‘sudo apt install xlibre’ and rebooted.

    Inxi -G reports the following:

    $  inxi -G

    How can you tell if XLibre is being used?

    This is a common question because XLibre still identifies itself as “Xorg”
    in tools like inxi or ps. So you cannot rely on the display name alone.

    Here are the reliable ways to verify that XLibre is actually installed
    and in use:

    1) Check installed packages (MOST RELIABLE)

    Run:
    dpkg -l | grep xlibre

    If you see packages like:
    xlibre
    xserver-xlibre-core
    xserver-xlibre
    xlibre-x11-common

    Then XLibre is installed on your system and replacing Xorg components.

    2) Check which X server binary is installed

    Run:
    ls -l /usr/bin/X

    On an XLibre system, this binary is provided by the xserver-xlibre package,
    even though it may still be named “Xorg”.

    ————————————————–

    3) Check running processes (NOT sufficient alone)

    Run:
    ps aux | grep -i X

    You will still see “Xorg”, for example:
    /usr/lib/xorg/Xorg

    This is NORMAL.

    XLibre is a drop-in replacement and keeps the same binary name,
    so the process name does NOT change.

    ————————————————–

    4) Check dpkg ownership of the X server

    Run:
    dpkg -S /usr/lib/xorg/Xorg

    If the file belongs to:
    xserver-xlibre-core

    Then you are definitely running XLibre.

    ————————————————–

    Conclusion

    If XLibre packages are installed AND the system has been rebooted,
    then XLibre is being used — even if all tools still display “Xorg”.

    This is expected behavior because XLibre is designed as a transparent
    replacement for Xorg.
