I installed LXQT with sudo dnf install @lxqt, like tjdoyle explained. It works well and I even have Openbox as a choice now.
Anyway, while I’m having three tabs open and some podcast playing sound I’m using 1.5 Gig, while I use 1.6 Gig while being in the Gnome environment. That’s a bit confusing! I guess one has to take into account how many cores the CPU or in my case the APU has too. It probably also depends on the graphics card, mine is a 2 Gig DDR3 Radeon card.
So, there is no drastic noticeable performance increase from Gnome to LXQT on my desktop system.
I was just testing, what Fedora Spin will work best on a entry level laptop with Celeron and 2 or 4 Gig RAM. I guess Openbox, but then I should learn how to use it first.
For now I will just keep the standard Fedora Workstation and use the LXQT from time to time. The only disadvantage with the standard one, is that Gnome sometimes crashes but quickly restarts or recovers some way. It also hangs sometimes for a few minutes. Maybe it has nothing to do with the desktop environment at all. I’ll use LXQT this week to see if it has fewer hiccups.
I have enough time until April or so when Fedora 32 comes out, to decide which to use. I’ll probably stay with the standard Gnome desktop, unless LXQT turns out to be more reliable. I don’t mind that it’s uglier.
Thank you for all the good advice about Fedora, I have been using it for just over a week and have never tried it before. Used Zorin for years and then I try something else, just to return to Zorin again because it’s easy to use and reliable.
Fedora is very good so far, very user friendly, not too demanding at all.
