Nvidia GPU (Prime) doesn't render anything, but works for CLI programs

Thaldir · 2021-01-11 16:38:32

Hello, so i've got a laptop with intel integrated gpu and Nvidia Gtx 980m, and for the last long while i've been trying to get any of the dual-gpu setups in the wiki, and failed miserably at all of them. This is my fail with Nvidia Prime, for some reason (cant find anything on google), xrandr failes to set the provider output source (as shown bellow).

The error im getting is that whenever im trying to open anything graphical using prime-run, i just get a non-responding black screen (or whatever was displayed there beforehand). i went over the Xorg.0.log, and the last thing you see in there:

[   667.201] (II) modeset(0): Modeline "1920x1080"x0.0  138.70  1920 1968 2000 2080  1080 1083 1088 1111 +hsync -vsync (66.7 kHz eP)

Is me trying to run blender with "prime-run blender", which resulted in a gray non-responding screen, and i had to switch to a different desktop, because whenever i hovered the mouse over it, the system froze for a moment. (killed blender through htop)

I can't find anything in the internet about this problem.

a few commands about my system+drivers+hardware+glxinfo with/without prime-run

the xorg setup is from here (was redirected there from the prime wiki)
prime in wiki.

Xorg config: (/etc/X11/xorg.conf)

    Inactive "intel"

Any idea what can cause this? (also is there any logs im missing? first time posting here..) Thanks in advance!

It seems that your NVIDIA card doesn't connect to any output. Your xorg config is strange and short. Maybe you can use

# Xorg :0 -configure

to produce a nice skeleton in /root/ and modify it to suit your needs. I configured my dual-card machine following the guide on the wiki page Xorg and it works fine now. Here is my /etc/X11/xorg.conf

I have the exact same behaviour !
No error what so ever in Xorg/journalctl but when I try `prime-run gltestperf` nothing is rendered on the screen.

What could I try ?
