Hi everyone,

I am impressed with EndeavourOS as it’s easy to install and use. But I have problem here with my laptop. I have optimus laptop with intel and nvidia 1050. Installed nvidia driver with nvidia-inst command. but when connect to external monitor, sometimes my external monitor only display black screen. and when I try to utilize nvidia gpu (exacmple: prime-run glxgears), my laptop will hang. And after force restart then external monitor with hdmi will normal. I have no idea how to find the root cause. Because it’s sometimes happen, and sometimes fixed it by itself. I hope some one will read this. I try with Optimus manager and now using supergfxctl, this issue still happen. I see error nvidia in dmesg. I google it found out some people experience this bug. But I don’t know to solve it.

Use EnvyControl or OptimusManager and switch into the Nvidia mode to have signal on HDMI.

Or instead of hdmi you can use type c to hdmi, or normal usb to hdmi if it’s support sending video signal over it.
USB to HDMI works in any mode, hybrid, integrated or nvidia, without need of EnvyControl or OptimusManager.

Please use code tags around the output you post.

Edit: It would also be helpful if you post your hardware output. Please post the url.

Oke, I think I have to write this. I reinstall optimus manager. and external monitor now work. But I have no audio. when I ran “dmesg | grep snd_hda_intel”
I got “Unable to change power state from D3cold to D0, device inaccessible”. Some googling found answer I have to add “pcie_port_pm=off” to grub. Restart My laptop and audio now work. I hope this is consistent solution.
