I'm running either no DE (IceWM or Openbox) or LXQT, of late. Can do without a DE, myself.
@darry1966 -- tried to install Devuan Beowulf on my D630, but it installed neither software nor a boot loader (tried at least four times each). Wanted LXQT. Miyo ran fine with just a WM.
BTW, good informative links re: xfce,mate,lxde. LXDE was once my favorite, but don't use anymore. XFCE I found frustrating re: panel. Anyway, I updated the info in my internal database (brain) and added to mental RAM (can lose it at any moment) -- LOL!
Currently PCLOS Openbox on one laptop, have to update hardware on the D630, it appears, but has Salix64 xfce on it at the moment.
@sp331yi Funny you should say that about DE I have been trying been trying fvwm and must say it is pretty light.
With regards to Devuan Beowulf I have advoided as I had same trouble with bootloader as they have changed how bootloader procedure is executed - it is done in a chroot. I installed the Refracta Beowulf instead for the reason that the broken su problem is solved in that. The only way I could get bootloader to work was to use grub repair from MXLinux.
