I heard like there is a new (Lightweight) Desktop environment available named as LXQt for Ubuntu and I would like to know how can I install it in my Ubuntu 14.04.
To install LXQt in Ubuntu 14.04 LTS open your terminal and paste these commands one by one.
that will install LXQt in your Ubuntu 14.04 LTS.
FYI: Currently there are many bugs. So don't try if having a stable and reliable system is a requirement for you.
As previously stated, if you want to install lxqt on top of openbox you can:
If you're trying to install it as the only desktop on a given thing you can use
And change the logging in to option on lightdm from KDE to LXQT.
It looks pretty neat and clean this way. I'll still have to go in and rip out some of the KDE icons/settings managers if I want it to look like an LXQT ONLY desktop with compositing, but it sure was easy to get it set up this way.
Note: I started with a server install as my minimal base. and it weighs in at about 3.6Gb installed, but lacks applications.
