  1. Thanks, great work! Tried it and it works like a charm :-)

    I just LOVE the LXQT project! The Razor-qt and LXDE devs made a very wise move. I think that Lubuntu and the Fedora spin will be great successes!

    Keep up the good work!

  3. Two things should be improved in this article:

    Unlike the package names may suggest this PPA does not provide release 0.9.0 but VCS snapshots.
    It would be helpful to reflect this in the text somehow, among other with regards to bug reporting.

    A while ago the PPA maintainers decided to split of all components related to session handling (menu items to log out, restart and so on) from upstream lxqt-session into a package lxqt-leave on its own for whatever reason.
    The latter is not a dependency of lxqt-metapackage which has already given lots of trouble to users. Metapackage lubuntu-next-core which seems to be a kind of successor to lxqt-metapackage does cover lxqt-leave and should hence better be used.
    Btw. it depends on lxqt-panel and openbox, too.
