I have the exact same Lenovo model, with the same BIOS version. Tested on Ubuntu 23.10 with kernel 6.6.6, with nvidia driver version 545.29.06 (both the proprietary and open modules), on Wayland and X, using HDMI or DP.
When "on-demand", there is no HDMI and no option to launch with dGPU. I do get the same exact messages as here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2033735/comments/39. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2033735 Title: No HDMI in Nvidia on-demand mode Status in linux package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-535 package in Ubuntu: Confirmed Bug description: Hi, Legion laptop with Nvidia. - Nouveau : no hdmi - Nvidia 535 dynamic graphics : no HDMI (screen not detected) - Nvidia 535 discrete graphics : HDMI is detected So I suppose this bug to be linked to Intel GPU.
