I see same problem after upgrading. Scripts that were written with idea that the laptop built-in display is always LVDS1, as it always was, no longer work. More bothersome, the assigned value of the monitor in xfconf-query statements seems to change, depending on what is plugged in.
This does work now xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/workspace4 /last-image -s /usr/local/share/Backgrounds/Animals/animals_lion- bcd2e615_dbg.jpg but in previous the "monitor0" was "monitorLVDS1". In fact, now that I check my notes, I realize all of the monitor bits ended in 1, "VGA1", "HDMI1", and so forth. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567287 Title: monitor names were changed since 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-panel/+bug/1567287/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
