Q: Being a very light-weight DE, how much RAM does
A: This actually varies greatly from system to system. But it is very much possible to run
EDE on top of an average Linux distribution with less than 96 MB of RAM! Starting up
EDE would increase RAM usage of an average system by less than 20 MB.
Q: Is PekWM the only WM that EDE can use?
A: No it's just the default one. In theory you could use any other window manager together with
EDE - however most combinations suffer of some more or less serious issues.
