### lxqt-session Dependencies

#### Required

liblxqt-2.1.0, qtxdg-tools-4.1.0, and Xdg-user-dirs-0.18

## Installation of lxqt-session

Install lxqt-session by running the following commands:

    sed -e '/TryExec/s|=|=/usr/bin/|' \
        -i xsession/lxqt.desktop.in &&

    mkdir build &&
    cd    build &&

    cmake -D CMAKE_INSTALL_PREFIX=/usr \
          -D CMAKE_BUILD_TYPE=Release  \
          ..                           &&
    make

This package does not come with a test suite.

Now, as the `root` user:

    make install

## Command Explanations

sed -e '/TryExec/s|=|='/usr'/bin/|' -i xsessions/lxqt.desktop.in: If you are using a display manager, the full path of the “TryExec” directive has to be given so that the LXQt desktop will appear in the sessions list.

## Configuring lxqt-session

Window Managers other than openbox-3.6.1 may be used, e.g. Xfwm4-4.20.0. Please note that IceWM-3.7.1 is not a good substitute. Fluxbox does work, although in this context (with lxqt-config-2.1.1), openbox-3.6.1 is better. The configuration file `/usr/share/lxqt/windowmanagers.conf` comes with many examples of Window Managers and the ones which are installed will appear in a drop down list of lxqt-config-session. For the ones not included in `/usr/share/lxqt/windowmanagers.conf`, you can use lxqt-config-session's "search" button, e.g. for Fluxbox-1.3.7, navigating through the file system until you can choose fluxbox.
