I didn't have all dbg-Symbols installed, following https://wiki.ubuntu.com/Backtrace I gave it another try. Please see the attached full backtrace by dbg. Still I didn't understand how to pass the "--sync" option or to run it in the GDK_SYNCHRONIZE environment. If anybody can tell me how to do it I'm willing to try. If anybody knows how to further debug it, please tell me -- I'm happy to help to get this solved.
** Attachment added: "full backtrace by dbg" https://bugs.launchpad.net/ubuntu/+source/unity-settings-daemon/+bug/1462590/+attachment/4540580/+files/gdb-unity-settings-daemon.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1462590 Title: unity-settings-daemon crashes using xrandr Status in unity-settings-daemon package in Ubuntu: Confirmed Bug description: turning the screen by running the command 'xrand -o right' turns the screen, but it then immediately comes back to normal. Then I get a crash message of unity-settings-daemon. This problem also leads to non-working key combinations, as CTRL + ALT + T to open a terminal or Fn + F1, Fn + F2, Fn + F3, Fn + F4 to control volume/mic or Fn +F5, Fn + F6 to control display brightness. In addition I then have problems running graphical applications from command line, not finding the display and/or returning Mir(!?) errors. Unfortunately I failed to create a bug report by submitting the crash report, so I'll attach it to this report and hope you can find all the necessary information. Feel free to ask for more information or mark it as duplicate pointing to an existing bug report.
