I have many minor annoyances with KDE Plasma 5.
This is my 2nd post this morning.

Whenever I reboot my PC when I get back into the syhstem the monitor layout and refrsh rate has been reset from what I had it set to AND 50% of the time a taskbar is missing from one monitor only.

I have 3 monitors. lets call them from left to right 1-2-3

Monitor max refresh rates: 1= 144hz 2= 165hz 3= 120hz

When I reboot the layout changes to 1-3-2 and monitor 3 has no task bar 50% of the time.
I have not tried rebooting twice (I will) but I always reset the layout, put the refresh rate back to 120 hz for all 3 adn recreated the missing task bar.

EDIT: Reboting multiple times changes nothing - the taskbar reamins missing until I restore it.


All that takes anywhere from 5-10 minutes.
Annoying as you know what, especially if I am in a hurry to get something done and leave the house, like this morning.

Thanks a bunch everyone.

Any suggestions on how to troubleshoot this would be MOST apprecaietd as I have no clue where to begin with this one.
