I have exactly the same issue on 15.10 with an intel card. philmmanjaro on github has published a patch to solve the issue. Just applies the patch on xfce 4.12 source code The workaround to fix this is the following:
$> sudo apt-get install xfce4-dev-tools libexo-1-dev libgarcon-1-0-dev libxfce4ui-1-dev libxklavier-dev $> git clone git://git.xfce.org/xfce/xfce4-settings $> git clone https://github.com/manjaro/packages-extra.git $> cd xfce4-settings $> git checkout xfce4-settings-4.12.0 $> patch -p1 < ../packages-extra/xfce4-settings/hdmi-power-cycling.patch $> ./configure --prefix=/usr --enable-pluggable-dialogs --enable-libxklavier $> make $> sudo make install $> sudo reboot now -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308105 Title: Xfce resets TV mode to NULL when power cycled To manage notifications about this bug go to: https://bugs.launchpad.net/mythbuntu/+bug/1308105/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
