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 Desktop Packages, 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. Status in nautilus package in Ubuntu: Confirmed Bug description: I have three monitors all hooked up to a Radeon 6950, using fglrx. One of the monitors is in portrait orientation and is a 1680x1050 monitor while the two monitors in landscape are 1920x1200 monitors. When I first select a wallpaper (say a wallpaper that is 1920x1200), it does the Right Thing. That is, the two landscape monitors show the wallpaper as you'd expect to see a 1920x1200 image on a 1920x1200 image display. The portrait monitor shows a slightly scaled portrait aspect rectangle out of the center of that wallpaper. When I leave my computer for some amount of time the wallpaper on the two landscape monitors is zoomed by what I assume to be the same percentage as the wallpaper on the portrait monitor. I say "for some amount of time" because if I set "Turn screen off when inactive for:" to 1 minute and "Lock screen after:" to 1 minute and then wake them up and unlock after a few minutes the problem hasn't manifested itself, but _every_ time I'm away from the computer for longer periods of time the issue has manifested. To fix, I merely change the wallpaper to another wallpaper and then back again. At this point the wallpaper displays correctly. See the attached image for screenshots of the issue.
