I made a fresh install of ubuntu 22.04.1, using latest driver 515.
The external monitor cannot be detected. On the windows installation it works normally.
Tried many solutions on the internet like switching to lightgdm, older drivers versions (470) but without success.
Hi.
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
Also changed:
/etc/modprobe.d/nvidia-graphics-drivers-kms.conf with
options nvidia-drm modeset=0
and then sudo update-initramfs -u
Could not find any bios update on the manufacturer site, but will get in touch to see if they have any updates available.
Current BIOS: INSYDE Corp. 1.07.11TBN, April 07, 2022.
In the meantime I tested on windows (same monitor, same cable) and it works out of the box. Could it still be a BIOS issue?
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
Yes, same issue. All external connectors on the intel igpu, 12th gen intel cpu+insyde bios with incorrect vbt [ 7.457037] i915 0000:00:02.0: [drm] failed to retrieve link info, disabling eDP
