LXQt 1.4 debuted today as the newest feature release for this lightweight Qt desktop environment that was formed years ago as the merging of the LXDE and Razor-qt projects.
LXQt 1.4 targets the Qt 5.15 LTS toolkit but if all goes well this will be their final Qt5-based release. By the time of the next LXQt version they hope to be fully ported over to using the Qt 6 toolkit, even if it means a drawn out release cycle.
LXQt 1.4 also has lxqt-menu-data replacing lxmenu-data, various improvements to the LXQt file manager, QTerminal now supports an audible bell as an option, the LXQt image viewer has minimal support for color spaces, many translation updates, and a variety of other smaller fixes.
XFCE and LXDE are nice in their own right. I used to run xfce and lxde on my laptops and netbooks. Those bottom of the barrel, underpowered, bargain bin machines hummed. At the time though HiDPI support was weak still (at least for xfce) so they never made it to my desktop. Didn’t like many multi-sized monitors. I assume this is a problem of the past now.
Xfce is my DE of choice. Hipdi support has gotten much better, though I’m using it on a 3200*1800 13" display so a simple 2x scale is all I need.
