You could probably just use 'xrandr --auto', at least that worked for me. I have actually now a different 'fix', by simply never having the system notice the hdmi-link goes down. I used this wiki-page to fix that for my Intel Haswell-cpu graphics.
https://wiki.archlinux.org/index.php/Kernel_mode_setting My final cmdline is now this: video=HDMI-A-1:1920x1080@60e dmr_kms_helper.edid_firmware=HDMI-A-1:edid/tv-edid-data.edid The tv-edid-data file is located in /usr/lib/firmware/edid/ and was derived via 'get-edid'. It actually also seemed to work with the built-in '1920x1080.edid' (saves you retrieving it from your receiver, but I thought it a bit more save to have the actual edid). Just supplying the video-parameter wasn't enough in my case, it failed to actually set the resolution to 1920x1080 (and used 1024x768 instead). Adding the edid-data fixed that (it may even be sufficient to only force-load the edid data). The reason this works is not because it fixes the issue, but because it prevents the hdmi-link from ever going down - as far as the kernel is concerned. -- 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
