OK, that makes sense, even if it is unfortunate. I'm fairly certain that my HDMI and DP connectors are connected to the dGPU, even if I never use them. So it makes sense that a backlight device get's created for that, I guess. Too bad that the code commentary says that there is no way to check whether it is actually needed, apparently.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
