I booted the 4.17rc1 kernel. In order to see output I connected an old TV to the DVI output, and that output was successfully detected (through an DVI-HDMI adapter, if that matters).
The output of /sys/class/drm/card0-HDMI-A-1 in this case: dpms: Off enabled: disabled modes: (empty) status: disconnected I then tried switching which monitor was connected to which port. Interestingly, in this case both the Dell U2415 and the old TV could show output successfully. // David On 2018-05-02 19:50, Harry Wentland wrote: > Thanks, mind posting the same for the non-working kernel?
