Quick follow-up for anybody curious. I did install Lxqt on 32 bit Q4OS. It uses about 60 MB more than Trinity.
As a desktop, I think I like Trinity better ( Trinity is essentially KDE 3 ). Some of the lxqt companion utilities were nicer though ( I liked lxqt-terminal more than Trinity Konsole for example ). Of course, you can install and use the tools with either desktop.
This has long been the best advice. However, just in case you are not aware, some pretty important NVIDIA changes are expected to drop in the next 2 months. It will take a while to work into every distribution but NVIDIA should finally work as well as AMD.
