No HDMI from laptop rtx 2060/ uhd 630

[Debian stable - driver 470]

The last bit I need to solve is the absence of HDMI from my laptop.
On Windows, it works. Not on Linux: it wakes up but goes black right after, with a “No signal” message.
Even tried screen sharing solution, nope.

I need that functionality to make my presentations on a bigger screen.

I don’t have xorg conf. Please find attached the bug report I just created.

Please set kernel parameter
After reboot and login, you might have to run
xrandr --setprovideroutputsource NVIDIA-G0 modesetting && xrandr --auto
to enable the external monitor.

Thank you so much generix, you saved my investment twice today.

I added your command in my bashrc and now it’s there forever.

Great to have someone like you on this forum :)

Again, thanks

Didn’t want to start a new topic just yet, but I am also having the same problem, however I already have modeset enabled. Posted some initial findings on my OS issue board here:

Nixos is special, please open a new thread.
Please run as root and attach the resulting nvidia-bug-report.log.gz file to your post.

sorry where can I get this script from?

nevermind, I found a copy of it, looks like it’s not installed by default in NixOS. Do I need to run this in a special context, like while an HDMI device is connected to the port for example?

Yes, connect the hdmi, then run the script with sudo on the desktop.
