I've confirmed that this bug is due to nautilus, but haven't been successful in fixing it (except for a workaround, described at the end of this post). The steps to reproduce the issue are:
1) Set the wallpaper using either the system settings dialog, or gsettings from the terminal (either method will display the wallpaper correctly) 2) Shut down nautilus by typing "nautilus -q" in a terminal 3) Launch nautilus again, and the wallpaper proportions will now be incorrect (the picture will be overly magnified on the larger monitor) In upstream, gnome shell is now responsible for rendering the background, and nautilus simply renders an invisible background over it and places the icons on top, as per these 5 commits on Feb. 20th, 2013: https://git.gnome.org/browse/nautilus/commit/?id=f0f36c876e4810b190a82e3a953d9263c106447f https://git.gnome.org/browse/nautilus/commit/?id=9f99ba3506d5cf1584d9afa952e11aed17deac2f https://git.gnome.org/browse/nautilus/commit/?id=8b4a83ea80bf657cd8be754786e5f9daf7d5cc52 https://git.gnome.org/browse/nautilus/commit/?id=07d2ca86237fac8b5bddc4e619e43dfc813bc5e7 https://git.gnome.org/browse/nautilus/commit/?id=372c60d3f8590280df23f457a67652adec369697 Applying the above patches to Ubuntu's nautilus gives strange results (severe flickering). So for now, I just made myself a simple workaround. I wrote the bash script below and added it to my startup applications: #!/bin/bash gsettings set org.gnome.desktop.background picture-options "stretched" sleep 5 # give a few seconds for the wallpaper to change gsettings set org.gnome.desktop.background picture-options "zoom" Basically you need to change the wallpaper mode, and then change it back to what you had originally (in my case "zoom"), and the wallpaper will be redrawn corretly. I hope that helps whoever else might be experiencing this bug. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1168705 Title: Multiple monitors with different orientation leads to stretched wallpaper when waking up.
