Yesterday's update messed up dual monitors

This happens a lot. Usually, I just go back into system config, split the display apart, rotate one of the monitors and then realign them. 5 minutes and I am done. Not today, however. After that rigmarole, the rotated monitor has one part of the display still in logically landscape mode. Consequently, menus and window placement will sometimes be off screen and the right-click-on-the-desktop does not work on the bottom half of the screen. It would probably work to the right of the top half, but the cursor movement does understand the layout and the cursor does not go there.

So, here is my question: Given that this is a semi-regular occurrence, what would be the best way to send the desktop developers a clue?

==> /etc/os-release <==
NAME=“openSUSE Leap”
PRETTY_NAME=“openSUSE Leap 42.1 (x86_64)”
I have a pair of Samsung SyncMaster 2253BW’s, if that makes any difference. And I have rebooted several times and rebooting will often clear this symptom.

I had hopes of helping you out with this… but it seems I too cannot extend my display onto two monitors right now. I don’t do it as often as I used to but through the KDE Display manager, I select apply and it essentially just flashes the screen and does nothing except remove what I just requested.

Hmm… Must investigate…


Thank you, Nathan. I am usually able to fix it with a few minutes of futzing around and get lazy instead of complaining about the new misconfiguration. However, today it cannot be fixed. My portrait oriented monitor is working in portrait mode. The windows show full length. However, menus go off on the right past the edge of the screen and the wallpaper does the same. That means some software thinks it is landscape mode and other software (like the cursor management code) think it is portrait mode (i.e. it is correct). Since it cannot be fixed this time, someone messed up worse than usual. :frowning:

Submit a bug. Be sure to include the video card and driver you’re using,
since the monitor make/model isn’t going to help resolve the issue (video
card is always the important component when it comes to video issues -
unless it’s obviously a sync rate issue).

I had first the problem with the latest nvidia update and uninstalled all nvidia. Running nouveau gave me about the same problems with my dual display setup. Having uninstalled the package virtualbox-guest-kmp-default as described here my desktop works correctly with both nvidia and nouveau.

I know I am about to give you basically useless information but for whatever reason, today, the dual display is working just fine to include the fact that it is not killing X when I add and remove the 2nd screen multiple times. I say, great, but I’d like to know what changed.

Thank you for the various suggestions. I am not using the Nvidia driver, so Nvidia updates should not affect me. I did file a bug so we’ll see about a response. I installed inxi, so system info is pretty easy to report now:

I too have experienced this (nouveau driver) and just go into the display settings (KDE configure desktop). This morning I had a fair amount of difficulty resetting the monitors, which usually just requires separating the two monitor icons and then selecting “apply.”

Today, I lost control of the desktop with the mouse (the pointer ended up in one display and the control panel in the other). This has happened before and fortunately the tab and enter keys on the keyboard enable me to regain control. But it’s a bit of a panic when this first happens.

Any idea which update(s) may have caused this? Nothing pops out when I review the update mailing list archive.
