Phoronix: Lubuntu 18.10 Officially Switching From LXDE To LXQt

After working on Lubuntu-Next for a while in transitioning from the GTK-based LXDE desktop environment to the modern and maintained LXQt desktop environment that is powered by Qt5, the Lubuntu 18.10 will be the release that officially moves over to the LXQt desktop and pushes out LXDE...

All the applications I use run on GTK toolkit - Firefox, Thunderbird, Libreoffice suite, JRE, etc. I don't see much reason to use QT based desktop, especially if you are running on a low end PC. I don't think this move to QT by LXDE is a good one. I am pretty sure Raspbian will stick to their version of LXDE.

I just wish the QT and GTK camps could put their heads together and make a unified theming framework.

We used to have a unified theming framework, at least conceptually. Red Hat developers deprecated theming engines in GTK 3.14 and made things like oxygen-gtk and QtCurve impossible.

Well, the point of LXDE and Lubuntu is being lightweight. Qt is anything but lightweight.

Qt is anything but lightweight.

Qt is used in Automotive/IoT industries and is most definitely lightweight because it includes everything needed to get the job done without needing outside dependencies.

Since SVG and CSS are both scriptable, could not a program be made to convert a Kvantum theme to GTK theme or vice-versa? However, with amazing themes like Breeze, Nota, and Ark having versions for both toolkits, I don't think it's worth the effort. Still, that wouldn't solve the difference between the Gnome and KDE design styles (human interface guidelines). To add to that, even if both projects adopted the same style, there wouldn't be a guarantee that developers would follow that style.

T.l.d.r.: So, it's probably never going to happen...

LxQT uses a bit more resources but still pretty lightweight.

Lubuntu 18.04 uses ~ 220MB (LXDE)
Lubuntu daily uses ~ 290MB (LxQT)

So should be still quite lightweight...

If you're running low end PC it's a big reason to switch to Qt. As far as I noticed if you run more Qt applications at once their memory footprint should be lower than gtk equivalents. Furthermore, Gnome 3 uses about twice as much memory as KDE: 480 MB vs 1.2 GB.
