New subthread.  Slightly new situation. 

New monitor came in today.  It seems the truck from Memphis got delayed
and didn't arrive in time for yesterday.  No idea why it took over 14 or
15 hours to travel what would take no more than 2 or 3 hours even by
truck.  Maybe the truck broke down.  Oh, monitor stand is stuck in the
USPS State hub still, like most packages do.  I have another unrelated
package that was sent to the wrong post office.  Can those folks not get
it together????  Anyway.

On the old LG monitor, when I first plugged up the new monitor, it
wouldn't power up from standby.  It wouldn't even when I connected only
the new monitor.  The BIOS would beep that it can't find a display as
well.  I thought at first I had a broken monitor.  Getting power but
won't wake up.  I tried another cable, it worked.  So, the first cable,
same as I used on the LG monitor, didn't work at all with the new
monitor.  Might be that the cable has a problem not the LG monitor
itself.  I didn't think of that.  I've used that cable quite often
before.  I'm not sure how old that cable is but it may find a trash can. 

On to the new monitor.  I'm trying to decide whether to use xrandr and
friends to set this up or xorg.conf.  Using both seems to cause a bit of
a clash and KDE isn't helping any.  I'd kinda like to go the xorg.conf
route.  I think, but not sure, that xorg.conf is read very early on.  It
seems, but not sure, that the xinit files are read later on.  I'm not
sure on all that.  It could be the other way around.  I'm also pretty
sure that if set up in xorg.conf, it would work if I logged into another
GUI; Gnome, Fluxbox or some other flavor.  It could be that xrandr and
friends would as well. 

Current situation config wise.  The first problem I noticed, the
monitors are nearly identical.  Even the serial numbers are only a few
digits off and that's the only difference I can see.  I did some
searching and was wanting to set a option in xorg.conf Monitor section
that identifies the monitors by not only model but also serial number. 
That way I could set one to right or left of the other, or above/below,
and it know specifically which monitor is which, even if plugged into a
different port.  I can't find a option for serial number yet.  I did
find where someone else wanted to do the same a couple years ago but
sadly, no answer to that question.  So, if that is not doable, may have
to specify the port number.  If I ever have to disconnect and reconnect,
getting the order right could prove interesting.  ;-) 

Right now, I have this:


root@Gentoo-1 ~ # cat /etc/X11/xinit/xinitrc.d/20.xrandr
xrandr --output DP-0 --off --output DP-1 --mode 1920x1080 --pos 1920x0
--rotate normal --output DP-2 --off --output DP-3 --primary --mode
1920x1080 --pos 0x0 --rotate normal --output DP-4 --off --output DP-5
--off --output DP-6 --off --output DP-7 --off
root@Gentoo-1 ~ #


From what I've read, that is the correct place for that command.  If
not, please let me know where it should be.  Keep in mind, putting it in
/usr somewhere gets overwritten when the package providing that file
gets updated.  I'm also attaching the current xorg.conf file.  Keep in
mind, gotta add the TV later on.  I think if I can get the monitors set
up, I can add the TV pretty easily.  Even if it only works in KDE, that
is fine since I need KDE up and running to use the TV anyway.  I'm
mostly needing to know if there is a way to add the serial number for
xorg.conf.  I think the rest is OK.  I also need a command to get what
the system sees as the serial number, in case it only sees a part of it,
last few digits or something.

I also had to argue with KDE about which is primary.  At first, like
with the LG, it wanted to make the second monitor the primary despite
the first monitor being marked primary.  I did the old set it backwards,
apply and then set it back the way I want it trick.  It took it a second
but KDE reversed it.  Main screen went to the primary display.  This is
what I mean by it clashing and me setting the displays up in xorg.conf
and KDE hopefully getting its info from that and adjusting itself. 
Plus, if I use a different GUI, it should work too. 

Oh, new hard drive for /home should be here tomorrow.  It's coming UPS
so they pretty good on delivery times.  They beat USPS every day of the
week.  Anyway, USPS claims the new delivery date for monitor stand is
tomorrow too.  When I see it in my mailbox, I'll believe it.  ;-) 

I plan to do some rebooting to see if things come up consistently as
is.  It has booted once the way it should.  Still, I'd like to set up
xorg.conf to make sure things work well despite any changes hardware
wise, like monitors plugged into different ports.  I think, could be
wrong, that is the best way long term.  I could use xrandr which is
likely the second best option. 

These new monitors sure are nice.  My old eyes like them.  o_O  Oh, I
was going to copy over the KDE config directories.  I think I'm going to
take the opportunity to give KDE a fresh start.  I think those old
config files date back to the switch to KDE4.  We on KDE6 now. 

If anyone knows if/how to set up xorg.conf with a monitor serial number,
plus chime in.  Other info welcome as well.
