.. note::
The ``qt5`` package requires (on Linux only) libraries not packaged in the ``m-labs`` conda channels.
Those need to be installed through the Linux distribution's mechanism.
If ``artiq_gui`` does not start because ``it could not find or load the Qt platform plugin "xcb"``, install the various ``libxcb-*`` packages through your distribution's mechanism.
The names of the libraries missing can be obtained from the output of a command like ``ldd [path-to-conda-installation]/envs/artiq-[date]/lib/qt5/plugins/platform/libqxcb.so``.
