LXQt is a lightweight Desktop environment. Some LXDE developers decided to create a Qt based version of their Desktop environment, it's name was lxde-qt. Around the same time some other people were working on a different minimal Qt based DE called razor-qt. When some developers of those projects met they decided to join forces and work together on one project. LXQt was born.
It is recommended to set the LXQt mix-in before emerging it.
Qt5 only system
LXQt depends only on Qt5, but polkit-qt has automatically set the qt4 USE flag. In case you are sure that you won't install any Qt4 applications which need polkit-qt you can disable Qt4 there resulting in a leaner System. Otherwise emerging LXQt will not just install qtgui-5 but also qtgui-4. In case your goal is to have a minimal, up to date Qt5 based system edit your /etc/portage/package.use file as follows:
/etc/portage/package.use- add or alter the polkit-qt line
root # eselect profile add funtoo/1.0/linux-gnu/mix-ins/lxqt root # emerge lxqt-meta
You can either use a display manager to log into your system and start LXQt, or you can log in on a TTY and run
startx to start xinit by hand.
You should edit the file
~/.xinitrc if it already exists, and put
"exec startlxqt" in there.
If it doesn't exist you can create it like this:
user $ echo "exec startlxqt" > ~/.xinitrc
You might want to add the commands and options
ck-launch-session dbus-launch --sh-syntax --exit-with-session to the
exec to start it with ConsoleKit and DBus.
In this case you also need to add ConsoleKit to the default runlevel:
root # rc-update add consolekit default root # rc
