--- Comment #245 from Michael Butash <mich...@butash.net> ---
So far, I've not been able to make 5.8.3 behave in the least in terms of
keeping the task bar entirely sticky to the actual intended monitor using
either nvidia-settings or kde settings/display. They definitely do not get
along, today I got sick of having it crash every day to force a hard reboot and
had some time to fiddle with it.
I did try as well the script mentioned here for giggles, which didn't do
anything for me at all.
I set up nvidia-settings as the defacto, and let it create an xorg.conf file
just to let it setup as standard old school style. My intention is always to
use my middle display, dp-2 as the "primary" for the taskbar to be sticky to,
but not since my old desktop on 5.7.2 can I get it to stay. I shutdown sddm
from alt vty, and removed .config/plasma*, .config/kwin*, and
.local/share/kscreen/* to reset things, and has so far helped some, but the
taskbar doesn't stay still when I shut off all displays, and most annoyingly,
it resets my center wallpaper every time. Same as it was in 5.5.x ubuntu 16.04
shipped with.
I have not used kde display properties since clearing these out. I tried
rearranging the dp-2 as the primary display as per the nvidia xorg.conf
setting, which only seemed to confuse kde more to move things around again. I
had to reset the xorg.conf file again with nvidia-settings to get the taskbar
back there, and reset my wallpaper.
I shut down all 3 displays again, again the center wallpaper resets, and the
taskbar jumps over to dp-0 on the left. Cairo-dock, which I seat atop in the
center stays there, it is set to use what it sees as "Screen 0 (middle)", which
seems to reflect what I had set xorg to, making the "middle" dp-2 as primary.
Almost every time, once I've shut the displays off and on at least 2 times,
almost certainly, the next time, it simply doesn't wake up fully, and crashes.
Here's my xrandr -q and xorg.conf currently. I see nothing obviously wrong
from .local/share/kscreen/kscreen.log, but I can post that as well with some
notation of events if helpful
