Ok, I have to confess. I'm a fan of GTK+ X-s for more than a decade. It started with XUbuntu, then I've switched from XFCE to LXDE and that was a love made in heaven.
As recently LXDE has migrated from GTK to QT it changed its name to LXQT and if you want to have a modern build of it you need to get used to its new face and APIs.
And let me tell you how painful that it is. Well, not as painful as if you switch from something as overbloated as KDE or Gnome. But nevertheless, everything looks and feels different after the switch.
The results of my migration to Debian-based SparkyLinux+LXQT are astonishing, XWindows + OS consume less than 256 MB of RAM.
Bravo! That's definitely a win.
