My wife bought a new Thinkpad, on which we had the shop install CentOS 7 (I *think* it's 7.3.) Alas!, I didn't think to specify NOT Gnome, in thunder. So of course I got it. I've tried several times to force myself to accommodate Gnome3, always with no joy. How do I get Mate or Xfce instead? Related problem: when I become root and tell it "yum update," it figures out a list of umpteen hundred rpms to update, but then runs through attempts at mirrors and keeps failing till it runs out. It failed to connect to my wireless router (or even to find it, afaict). So I plugged it into the router with an ethernet cable. No joy.

How do I get Mate or Xfce instead?I hope this doesn't sound rude, it's not meant to, but have you googled for it? The first hit on 'install xfce centos7' or 'install mate centos7' gives the answers in much more detail than I can go into here. But basically, install epel and then yum groupinstall "Xfce" or yum groupinstall "MATE Desktop"> > Related problem: when I become root and tell it "yum update," it > figures out a list of umpteen hundred rpms to update, but then runs > through attempts at mirrors and keeps failing till it runs out.

Can you see websites? If you can't see the outside world, updates aren't going to happen. P.

No joy.This sounds like you have cached metadata that points to older files that are no longer on the mirrors. Try running 'yum clean metadata' and try updating again. -- Jonathan Billings <billings at negate.org>

No joy.The ethernet adapter seems to be turned off by default. To turn it on, click the 'down arrow' in the upper-right corner, then click the Settings icon (a crossed wrench and nutdriver, near as I can tell) and choose Network. Then, in the Network dialog, click Wired on the left and toggle the 'switch' in the right-hand side to ON. If you make a profile for it there, you can have it connect the wired adapter automatically (which turns it on automatically, too). In any event, you should also see its status (e.g. connected or disconnected) when you click the down arrow in the upper-right corner. Getting the wireless working *might* go smoother once all the initial updates are installed.

We had a lightning strike a month or so back that must've been right next to the house: blindingly bright, and with huge thunder simultaneously. It fried both the cable modem and the router; and I haven't yet managed to install DD-WRT (or whatever may have succeeded it) onto the router.
