[olug] Fedora 23 Upgrade Notes

I updated my five Fedora servers this weekend via dnf, and it was pretty 
uneventful.  On four out of five servers, I will even go so far as to 
say it was painful.

The fifth server, though ... there was a very poorly-timed brief power 
outage in the middle of the process.  I was afraid I'd bricked the 
server, but fortunately, the server booted up okay, and was willing to 
do the update like nothing happened.  It was crazy slow, though, like 12 
hours or so.  So I get the feeling the power outage did confuse the 
update process, but the update process worked through it rather than 
giving up in frustration. Well done, Fedora 23!

> kernel with the RPMfusion nvidia driver.
> Downgrade command:
> dnf --releasever=22 downgrade xorg-x11-server-Xorg
> Until such time that the full version of 1.18 is out and nvidia updates

> exclude=xorg-x11-*
> .... clip here ....
> If you don't feel up to making all these changes, perhaps waiting a month
> (hopefully) to upgrade to Fedora 23 would be the best course of action.  I
> would have waited to upgrade my desktop had I paid more attention to some
> of the forum posts from a few weeks ago.
> If you're using an intel graphics adapter or the nouveau driver, you should
> be fine.  Those with optimus hardware or the latest nvidia cards should
> probably wait.
