What you say is correct, the case I want to make is like the following: 1) When nothing is connected it shows zeroes. 2) Keep program running 3) Plugin HDMI 4) Stop program 5) Start program -> encoders are still 0. The state in (5) will not change no matter how often you stop/start the program. You need to unplug/replug HDMI again to make it work. This happens on Kaby Lake for me. To me it looks like an issue if a user space programm has a file handle to /dev/dri/cardX and the state of HDMI goes from disconnected to connected. Please let me know if you need further information.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
