Just to be absolutely clear, it doesn't seem to be a requirement that the TV eventually gives up and turns itself off before the behaviour manifests on my laptop. I have caught it "searching" for a signal (although not cycling between inputs), but I was too late to save my laptop from going into this state where it no longer detects the external display. Also, I can unplug and replug the HDMI cable, and the TV detects that there is a connection (display changes from "No signal" to a blue background, but eventually goes back to "No signal"), but the laptop does not detect the external display. Also, if I use a USB-C to HDMI adapter, it does detect the display being connected while in this state, but this is not a great solution because the laptop does not appear to like the USB-C to HDMI adapter being disconnected. This is what I get: [377553.263099] usb 3-1: USB disconnect, device number 2 [377553.363447] xhci_hcd 0000:3d:00.0: xHCI host controller not responding, assume dead [377553.363451] xhci_hcd 0000:3d:00.0: HC died; cleaning up [377553.380937] xhci_hcd 0000:3d:00.0: remove, state 4 [377553.380940] usb usb4: USB disconnect, device number 1 [377553.381199] xhci_hcd 0000:3d:00.0: USB bus 4 deregistered [377553.381346] xhci_hcd 0000:3d:00.0: remove, state 1 [377553.381349] usb usb3: USB disconnect, device number 1 [377553.381725] xhci_hcd 0000:3d:00.0: Host halt failed, -19 [377553.381729] xhci_hcd 0000:3d:00.0: Host not accessible, reset failed.

Or perhaps there is a better mailing list (graphics driver focused) that I should be sending these reports to? Thanks Rogan P.S. Any idea why I can only see these messages on the HyperKitty list interface, rather than getting them in my email? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
