    Exclamation KDE 5.8 Resets my Dual-Monitor Configuration on Every Reboot

    Hello. I've been using OpenSUSE as my sole operating software for about a month now, and I've been able to fix (with help from you kind folks!) every problem that's cropped up so far. I'm confident that we can fix this one too.
    So. I have two monitors. The problem started when I used "zypper dup" (carefully. Nothing else broke.) to upgrade from 42.1 to 42.2. I use folder view, if that matters.

    The first time I booted up, it had the wrong display set as primary, and on the wrong monitor. On the other monitor, all of my widgets were gone, along with my desktop background. I fixed the settings up, changing the desktop background on the second monitor, putting the monitors in the right order, adding my clock back... the works. I was thinking it had just lost its path to a config file or something.

    Lo and behold, next time I reboot (pretty soon, I was checking all of my applications after the dup) it reverts back to that state. Secondary monitor has primary display desktop, primary monitor has a default desktop. After a few days I got tired of the mixture of not rebooting/reconfiguration I was living with, and started to try things. One of the first things I tried was to change in the plasma system settings "startup and shutdown>desktop session" menu from "new session on boot" to "restore last session." This worked like a charm, but again, I got tired of the side-effect, in this case significantly slowed login times. I tried going back to new sessions every start, just in case it had jogged Plasma's memory and it would now work, but it immediately went right back to the way it was when I first booted into 42.2.

    So I suppose I'm looking for insight. Are there config files? Are there settings that I have to work with as root to make persistent in the new version of plasma? Is this a known bug? Is there a basic setting I'm missing?

    Thanks,
    --Henry Wilson

    Try to install the pending Plasma update from the update-test repo.
    It contains some fixes for multi-monitor systems, your problems do sound like they should be fixed by that.

    See https://forums.opensuse.org/showthre...67#post2800267 for more details

    Btw, "restore last session" has absolutely no influence on Plasma or the monitor setup. It just restarts applications that still run on logout when you login again. Of course this can/will slow down login, and the different timing may make a difference in regard to your problems...

    Thanks, sir! I will try that as soon as I get home from my weekend trip in Boston, and report back. Much appreciated.

    Alright, that has partially worked. It now remembers the order my screens should be in, but it still forgets widgets and desktop backgrounds on my secondary monitor.
    This is really helpful, because the widgets and desktop icons are not actually important. But I'd be happy to hear any further ideas! Thanks.

    The problem would seem to have resolved itself in updates last night. All is working well now. Thank you!
