This is affecting me on Mythbuntu 16.0.4.3 - with all updates applied as of 10.09.2017. Machine is an Intel NUC NUC6CAYS.
Display is a Panasonic TV connected via HDMI. As with other users above running xrandr --output 'DP-1' --mode '1920x1080' brings the display back to life, as does restarting X11. The problem can be cured by killing xfsettingsd. dmesg and Xorg.log (concatenated together) attached so that you can get a sense of the hardware involved. Sorry not sure whether this issue is Ubuntu specific or whether the bug belongs upstream with the XFCE guys. Happy to help in any way I can. ** Attachment added: "dmesg_and_xorg.log_concatenated_together" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1308105/+attachment/4947276/+files/dmesg_and_xorg.log_concatenated_together -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
