This is a custom Ubuntu ISO build for development and testing of the latest LXQt code. It uses the LXQt ppa, so there is some risk of explosion (but in my experience is very stable). I tried to get the best Qt applications available, which in my taste means some KDE apps. THIS IS NOT AN OFFICIAL ISO.
This is my personal preference, it is a very minimal style, but LXQt can be tweaked to look as whatever you like.
