[Xorg] Cannot connect external display

Good morning,

I currently have a computer equipped with a Nvidia graphics card (GTX 1060), so I installed the proprietary drivers and Bumblebee. Everything works well except that it is impossible for me to detect any external monitors, which is not very practical for my work. I try to connect it via HDMI and arandr or xrandr detect nothing. Do you have any idea?

Thank you in advance

Re: [Xorg] Cannot connect external display

I'm assuming that you have bumblebee because you have an integrated graphics processor as well as an Nvidia processor.
Have you installed the nvidia-settings utility https://www.archlinux.org/packages/extr … -settings/ yet? That might detect the ports that arandr and xrandr are missing.

Also, according to the Bumblebee ArchWiki page, it lets the integrated graphics processor manage the displays while the Nvidia card would only do rendering work. This means that if your external monitors are connected to ports from your Nvidia card, they won't be detected because they aren't even active. I'm thinking that right now, your only working with the ports that your intel graphics chip can connect to.

If I'm right, I'm not sure how to remedy this problem. Try disabling Optimus and letting your Nvidia card manage everything. You'll probably be able to use the HDMI ports then. You should still install the nvidia-settings utility anyways because it give very easy access to the different display settings.

Re: [Xorg] Cannot connect external display

Yes I've bumblebee because I've an integrated graphics processor.
I've install nvidia-settings but I didn't find anything that can solve my problem.
Even when I disable bumblebee I cannot connect an external screen. Do other people have this problem ?

Re: [Xorg] Cannot connect external display

Please post lspci -k , xorg log , xrandr -q and glxinfo | grep -i opengl

(glxinfo is in mesa-demos package)

Re: [Xorg] Cannot connect external display

xrandr --listproviders
xrandr --verbose
optirun xrandr -q # just guessing this might actually produce relevant information

The nvidia chip is an actual VGA controller which might be in charge of the desired output - you'll have to set the nvidia chip as sink to the intel one (loosing the outputs controlled by that chip) or run two independent x screens.
