Originally I installed Fedora 17 original one (that with Gnome) on my laptop but out of curiosity I have several other DEs on my laptop as well.
What I did is :
yum groupinstall LXDE
yum groupinstall FXCE
also I have MATE on my laptop, following the guide on forum.
since they were just installed for curiosity and I don't use anything other than Gnome practically, I'd like to have them removed. My GDM tells there are 7 DEs - openbox, gnome, lxde, fxce, mate, gnome fallback, xbmc. I can't even tell where the hell openbox came from.
I tried removing unused DEs with Add/Remove Software -> uncheck lxde/fxce/mate in "package collections" list, and the add/remove software tells me that it has to remove other packages as well, namely nautilus, gdm, etc. Is it okay to just click okay? I'm very scared about this.
