I have an old Dell PowerEdge SC1420, which ceased to be a server
or to have any form of RAID years ago, when I inherited it. Over the
years,
I've run many releases of Fedora on it, one or two of CentOS, and I
disremember
what all else.
Some OSs figure out my HP w2207h monitor on contact, even from
behind the KVM switch where I normally keep the SC1420; the last few
Fedora
releases have been good about that, iirc.
Some OSs don't find out how to display anything while behind the
switch, but do if I shut everything down and connect the Dell directly
and alone to the peripherals.
Some OSs never get it; I have had to tinker endlessly with
xorg.conf a/o grub.conf.
But now F21 doesn't get it, and I can't seem to find a file that
will let me tell it there is such a thing as a 27" 1680x1050 terminal.
(The only plausible candidates so far open with DO NOT EDIT THIS FILE, and
a reference to the other files that set them; but I'm drawing a blank
about any way to reset the setting files.)
I can ssh into it, and have been updating it regularly; a few
days ago it even accepted a fedup (nonproduct).
Also, for a little while today, I had a Gnome3 display; I managed
to open a Mate-terminal; but before I could get to a panel, much less a
workspace switcher (one of my must-haves), it suddenly jumped into a
display that looked like a few lines torn from the normal boot messages.
I couldn't faze that, and finally hit Ctrl-Alt-Del. That got me
to a normal looking boot, except for one "FAILED," which went by too fast
to read. Then, for a little while, it went back to the Gnome3 screen, in
which I had begun adding and removing apps.
It didn't want to start yumex as root *nor* as user; so I told it
"yum remove evolution," thinking it would keep the data-server, or
whatever that thing is that stays when I remove Evolution with Yumex. It
didn't, and chaos ensued -- till it hit the abominable error message from
the monitor, saying "Input out of range."
Clue, please?
