Multiple monitors reset to default at boot and log logon

[Jérôme Fortin]

I recently install Kubuntu 19.04 and updated everything.
Those issues where not existent in Kubuntu 18.04 LTS (same machine setup)

EVERY TIME I LOGON IN KDE my monitors positions are reset to some default settings.
So I have to specify my monitors position each time I open a session. And not only after a boot or a reboot. It is becoming annoying really fast.

Yes there is a new software asking me what setup I want for my monitors. At first it seem nice but it turns out that it's asking me every time I logon. Event when monitors are already plugged in and have not change.

Most of all, it dose not let me set my monitors in the disposition I would like. For instance top and bottom are not include. And it can only manage 2 monitors and I have 3. For now I found a way to disable it since it doesn't help me at all.

This situation is not coming from the fact that I have 3 monitors. Before setting up my USB to DVI adapter (form Display Link who are providing Linux drivers) and added a third monitor, I was working with only 2 for a while. The experience was not good at all. I was and I am still tempted to go back to 18.04 just to get rid of this annoyance.

With Kubuntu 18.04 my 3 monitors where always working fine. And when I was unplugging one or tow of them going on the road or when I was plugging my laptop in the living room or else where to watch a movie or some thing the system was simply adapting without any intervention. It almost seem to remember each reoccurring setup. It is not the case anymore.

Now I have to use the GUI utility each time I logon and when I do sometting else with my laptop too. And the GUI is toying with me. The screens representations are acting up playing tag or something whit the mouse pointer and one an other. A similar issue was present in 18.04 but some how it got worst. I think I will make an other bug report for this one.

Solution
At logon all connected monitors should be in clone mode. When ever xorg or kde manage it.
Then the system should remember how the screen where last time and simply reload these setting.

A software should only ask me what to do if and when I plug a monitor in a live session or maybe if a new monitor is detected at boot time or logging time or if I open it.
And this software should let met position monitors as I would like. Including distances between monitors as the GUI utility let me do. Well after I manage to catch those pesky screens and position them in relation to one an other...

Even better
Since laptops or tablets (and sometimes other computers) are not always plug the same way. I would like to have display profiles to chose from. And have the suggestion to create a new profile (not erasing the current one) when new monitors are found. When monitors of current profile are not available it would also suggest to create a new profile. And when the hardware is corresponding to a existing profile is present it would simply load it without asking.

Here some example
- Read only profile : Laptop monitor only (on the road)
- Read only profile : Duplicate all screen (for 2 3 4 monitors...)
- Custom : My Workstation (when I'm working in my home office (3 monitors))
- Custom : Client 1 (when I'm working on at a specific client office (2 monitors))
- Custom : Relax (when a plug my laptop on my TV in my living room)
- Custom : TEMP (This one would be for temporary setup use at other client and friends places)

Well it is my first time reporting a problem here and about Kubuntu. Hope no one will complain about my English or my method but explain what I should do different next time. There is improvement that I like in 19.04 and I am hoping for the best.

Thank to the community!
