Thanks for the reply. Could you point me some link to do the grub and modprobe part?
I changed /etc/default/grub with:
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash nvidia_drm.modeset=0”
and then sudo update-grub
options nvidia-drm modeset=0
and then sudo update-initramfs -u
Yes. Seems to be some bios dev at insyde not knowing how to build a proper bios. The intel windows driver can override this so it works. The intel linux driver unfortunately relies on the VBT to be correct.
I’m facing what seems to be the same or a similar issue, using Ubuntu 22.04 LTS, on a laptop with a GeForce GTX 1650 Mobile / Max-Q.
I’ve tried pretty much everything I could find on forums (reinstalling the NVIDIA drivers, using different versions of NVIDIA drivers, using Liquorix kernel, not using NVIDIA drivers at all, using different cables, different monitor, HDMI, Mini DisplayPort, secure boot disabled, etc.) but no output on the external monitors at all.
My BIOS is also from Insyde, version 1.07.13TBN, 06/09/2022
