I am so happy installing this distro. Now I get to try it out! Thanks to the team for a wonderful installer and welcome screen as well as the love and work that has gone into this arch based distro!!
I just install endeavor OS with lxqt, xfce, gnome, and plasma. Is there anything I need to be aware of?
You installed all at the same time?
Make different users for each DE TI separate config files.
Welcome to the purple side! 
Yes. The journey is gonna be fun 
On a serious note, I’m not sure if Gnome and Plasma will get along with each other. I haven’t used either of them as daily drivers, but I have heard about one DE overriding the settings you change from other DE. Also, your app list is gonna look cluttered. Probably more stuff other forum members can tell. I’m a window manager person 
Welcome to 
forums.
You missed BSPWM, i3, Cinnamon, Sway, Bugi, and MATE 
.
You might run into issues if you installed all of the DE’s (desktop environments) under the same user account.
Did you mean buggy
Yeah that I’m kind of in the clouds at the moment … if you get my drift.
Okay? 
… btw
Welcome to the Purple neighborhood! 
Just make different accounts for each DE (just like it did) and you will be fine.
That sounds familiar … oh yeah, I did that once … brace for impact captain ! It is gonna be a bumpy ride ! (read with Zulu’s Japanese accent)
Seriously, it is gonna be bumpy.
Welcome.
Welcome!
