I do know that Trinity DE is the fork of KDE3 and also read that LXDE is more RAM resource friendly.
But Trinity DE in q4OS consumes 70 MB RAM and Sparkylinux LXDE consumes 130 MB RAM and Robolinux lxde 32 said to use only 66 MB RAM but four times ROBOlinux iso failed to work.
q4os was awesome for internet usage but for daily use, no it sucks.
Sparkylinux is still the best.
I also know Debian doesn't have Trinity DE and few Debian Stable distros use it.
Unfortunately Trinity DE doesn't work for Debian Testing.
