Hi,
Turning off a connected TV, and then turning it on causes issues with re-negotiating a connection to the display.

The error message was pasted into an open document that was actively under edit with the program nano. I assume messages are sent from somewhere destined for stdout; or something has redirected it. Either way, I think this may cause issues with bug reports. It looks like a dmesg entry.

The error was '[id] noveau 0000:0b:00.0: DRM: DDC responded, but no EDID for HDMI-A-1'

Possibly an issue parsing EDID information, or this display botches sending EDID information.

Running Debian 12 Bookworm in multi-user mode, display device is NVIDIA RTX 3060Ti, display is LG C3 OLED running on outdated firmware. I am uncertain if updating the display firmware would fix the issue, and I have no access to up-to-date firmware.

Feel free to ask any questions.

Regards,
