There are no held back packages when you format the system partition. I did it at first, keeping files in /home, and even with all packages removed/installed afresh, this didn't do it. Settings are being not properly migrated from 15.10.
I nevertheless leave this bug as invalid, as it won't occur on a new machine. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1556202 Title: Dual monitors not supported with resolution 3440x1440 and Full HD Status in xorg package in Ubuntu: Invalid Bug description: I connected one 3440x1440 monitor (DP, primary, left side) and one Full HD monitor (HDMI, secondary, right side). Clock was displayed only on the left hand monitor, but clicking the settings button in the upper right corner of the left monitor would display the popup menu on the right monitor. It was hardly possible to hit anything with the mouse, as the cursor was moving correctly, but clicking would activate a button different from the one directly below it. Clock and the launcher would look correctly, but the windows were ugly and hardly legible. I had to move my windows to the very left edge of the left monitor to hit soft buttons correctly. It looks like the "clicked" coordinates were being translated to the overall width of the virtual desktop System Settings detected both monitors correctly.
