Hello Linux Geeksters. As you may know, the LXDE developers have started the porting of their LXDE desktop environment to Qt, the new project being called LXQt. While LXDE is based on GTK+2, the developers have decided to port LXDE on Qt5, instead of GTK+3.
Due to the fact that LXDE is lightweigh, it is very popular on Linux systems, being ideal for computers with modest hardware specifications.
The LXDE developers have posted an article giving RAM consumption numbers of XFCE, LXDE and LXQt, all this systems running on a virtual Debian Testing system with 512 MB of RAM and a single core processor:
- XFCE: 89 MB (with default configuration of Debian. This value will increase after xfce is ported to gtk+ 3)
- LXDE (gtk+ 2 version): 78 MB (add 20 MB to openbox)
- LXQt: 95 MB (add 37 MB to openbox, still has some room for optimization)
Also worth mentioning, due to the fact that LXQt is still under massive development, Lubuntu 14.10 will be still using LXDE. If you want to test LXQt on your Ubuntu 14.04 or Ubuntu 13.10 system, see the instructions in this article.
