Forcefully resetting the Display with xrandr commands
Kernel used: 4.8-rc5 drm-intel-nightly. Also reproducable with mainline 4.8-rcX Peter - sorry about this delay until getting back to you. Due to this delay, which is not your fault, I need to ask if this failure is still valid for the latest drm-tip kernel? If yes then please provide new dmesg for your well described use case. Peter it has past couple of months with no response from the request in prior comment to test again with a newer configuration. If there is no response in 30 days the bug will be closed @Ricardo: Please close it. I don't have that hardware up and running anymore and therefore cannot verify. Thanks for coming back to me. |

Created attachment 126455 [details] Display switching to black screen from 23.976 hz to 50 hz When switching from a 23.976 modeline back to 50 hz after e.g. movie playback with xrandr, the screen turns black. It only helps to reset the screen by either: - Remove the HDMI plug and plug it back in - Use ssh with: xrandr --output HDMI2 --off && xrandr --output HDMI2 --auto Logs attached: Log after it switched to black screen Log after xrandr --output HDMI2 --off && xrandr --output HDMI2 --auto was applied
