Making Lubuntu 16.04 more pixel efficient


With the panel on the left or right, you get more visible space for content in portrait orientation, like word processing documents and websites and you don’t have to scroll as much. Ubuntu‘s Unity desktop environment got that right.

If you have a low resolution screen this is even more important. If you only watch films on your computer, then the “traditional” Gnome 2 and Windows layouts work fine. The traditional layouts also make more sense on a “traditional” 4:3 screen since the screen has more space in the height compared to the width than modern wider screens (16:9 or 16:10).

In addition to scrolling less and seeing more content, I also find this layout functional and a bit more beautiful than the «traditional» layout. It is possible to use a more fancy dock like docky or plank in stead of the LX panel that comes with Lubuntu, but then you also need compositing and that makes the machine a bit less energy efficient, even if it looks beautiful, so I prefer to just use LX panel. It is possible to use translucency without compositing and it looks quite nice in my opinion.

The advantages of using Lubuntu with the LXDE desktop environment in stead of standard Ubuntu with Unity is mainly that it is faster, runs better on older hardware, uses less RAM and CPU and GPU cycles, uses less energy (= longer battery life on laptops) and is more tweakable. Even if I like Unity, Lubuntu lures me back time and again and I enjoy using it a lot. At present, I use it on my laptop after a period of Manjaro Gnome. I am probably more of an LTS kind of guy even if I like the idea of a (slow) rolling distro.

I have made a video showing how to tweak LXDE to be more pixel efficient than it is out of the box on Lubuntu. I also change some other aspects of the look and feel more to my liking. The goal is to get something like what you see on the screenshot above. (There is no sound in the video.)

Here is a step by step guide if you didn’t get all of it from the video.

(14. Set Tux image as menu icon by double clicking “Menu” in the “Application launch bar” tab and selecting the Tux image in the open dialog.)

A special thanks go to Leszeck Lesner for the Lubuntu screencasts from some years ago that taught me how to tweak Lubuntu! 🙂
