Kubuntu (22.04.2) Not Detecting External Monitors with GeForce RTX 3050 Laptop GPU (525.105.17)

Hello everyone,

I am experiencing an issue with my laptop where external monitors are not detected when running Kubuntu on an NVIDIA graphics card. I have tried to reinstall all, firmware update, and different settings, but I do not get it working. The external monitor shows a dublication until the os takes over, so I guess it must be software related.

I will attach some informations to the text. I also have a bug report
nvidia-bug-report.log.gz (536.8 KB).

Thank you for reading and in advance for your help.

The nvidia gpu has no outputs, all are on the intel igpu. Your hdmi not working is due to a known i915 bug with 12th gen cpus. Don’t know whether a fix exists yet.

Thank you that is already helping. Do you have maybe a link to the bug? If I understand it correct, I have to hope for a newer kernel fixing this bug?

I googled;
Possible this bug?

Do you know if any linux distribution can deal with it?

The general i915 or better said, common insyde bios bug had two effects
internal display not working after suspend
https://gitlab.freedesktop.org/drm/intel/-/issues/5531
which was fixed in kernel 6.3
hdmi port not working
https://gitlab.freedesktop.org/drm/intel/-/issues/7709
which wasn’t fixed yet (apart from a kernel hack)
The common workaround was to use a DP port on the notebook, if available.

Ok. That’s helping a lot.

I have an mini displayport, I will try that as soon as I get an adapter.

Maybe I will also try to compile the kernel with the hack, but not now.

Thank you a thousand times. Great help.
