Dear Bug Triager, I have now realized that the Xorg team won't look into Xinerama issues as they claim that it's deprecated in favor of RandR. Please feel free to mark this bug as Won't Fix as that better reflects the reality of the situation from the standpoint of the Ubuntu developers.
FOR ANYONE ELSE WHO MAY CARE ABOUT THIS: At some point I realized that both Xinerama and the Compiz window manager where causing this problem. Besides the bug issue reported above, the setup was causing very slow graphics performance and a few crash reports. Sticking with Nvidia proprietary drivers, I made the switch to BaseMosaic (instead of Xinerama) and moved away from the Unity/Compiz combination and on to Gnome-Classic/Metacity (Non-composite window manager). For Gnome Classic the package to install is gnome-session- flashback, and you need to use it because Unity requires a composite manager while Gnome Classic does not. This nearly solved all problems, but then I found resume from suspend not working properly. Resume from suspend was working in the sense of restarting the system again (I could ssh into it), but the display monitors remained black. The culprit was the Nvidia propietary driver, which I finally removed in favor of the nouveau driver. Last but not least, a bit of shifting monitors around with xrandr, and problem solved! To sum up, use: - Gnome Classic Desktop Environment - Metacity Window Manager - Install a dock launcher like cairo-dock if you are missing Unity's dock - Nouveau driver - NO xorg.conf file! - Xrandr if you are not getting the correct monitor layout - place the xrandr command in an executable shell script, and include the script in the startup apps. ** Description changed: + NOTE: Ubuntu won't fix this bug, but if you are interested in a work + around, read the last comment! + + ORIGINAL BUG REPORT: + To reproduce on a fully updated Ubuntu Desktop 16.04 system with Unity: Step 1: Start nautilus Step 2: Drag and drop a file to any target: to a different folder in the same nautilus window, to another folder in a different nautilus window, etc. ...
