I don't believe that this is a TV issue (other than its behaviour on input loss triggering the resulting behaviour on the laptop). This is because if I reboot the laptop, the TV is quite happy to recognise it again, while disconnecting and reconnecting the HDMI cable does not have the same effect.
I can perhaps look at interposing a breakout board on the HDMI cable, and using a logic analyser on certain pins (i.e. those that carry the DDC protocol used to enumerate the display modes supported by the connected display). That might allow me to see that the laptop is or isn't recognising that the display is connected and performing the DDC interrogation. But I imagine this would also be possible by enabling verbose logging too, which would probably be a lot easier in the short term. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
