Coming from windows server/MacOS...
I've been researching for my first linux deployment and I have settled on Ubuntu/GlusterFS for a high performance file server.
I have a question about the resources needed by GUI. I understand this is a server and it should be bare bones for performance, but I have a situation where this server might be administered occasionally by a non-technical person that is not comfortable whatsoever with command-line. I don't want light versions of applications, if they get distracted and watch youtube videos, dropbox uploads, email or whatever they do while at the server that does not bother me whatsoever. What does bother me is getting a call because youtube/dropbox doesn't work on the server and they didn't want to leave the machine room.
In my research I've only seen absolutely negative things about the gui resource use. Some reports are as high as 50-60% resources used by gui alone. Is this applicable to a purpose built machine, something like 36 bay supermicro with top line dual processor/128GB/256GB RAM, or is this only relative to minimum spec boxes?
Also, is this happening when these heavy packages (mediaplayer/browser/etc) aren't open, or only when they need processing? If they don't use resources other than disk space, no big deal. Even if they use a bit, that's fine too, I would willingly give 4-8GB RAM overall, which is waaaay too much, but I really don't want that call. There will be sufficient headroom built into all aspects of resources.
Would it be beneficial at all to install ubuntu server and then the gui over the top, or is the full gui version of ubuntu fully capable as server OS, just bloated and prettier?
I am coming from no linux experience, so to see this sort of server with gui specific comment is very alarming.
Any help appreciated, thanks Y'all
