[SOLVED] xrandr: Configure crtc 4 failed

Hi guys, I'm having trouble with my external monitor.
When I try to enable it, xrandr throws a strange error:

$ xrandr --output HDMI-1-0 --auto
xrandr: Configure crtc 4 failed

I'm on Linux version 6.2.12-arch1-1 and nvidia 530.41.03-5 (my laptop has AMD integrated graphics and an Nvidia card, I don't remember which one is used by default though)

Output of xrandr:

My laptop only has one HDMI port.

I looked around on the Internet and I didn't find an answer/solution to this problem. Can someone help me? This is the first problem I haven't been able to solve myself in 3 years of using Linux

Re: [SOLVED] xrandr: Configure crtc 4 failed

I don't remember which one is used by default though

Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General

Does only "--auto" fail or also "--mode 3840x2160"?
What about "--mode 1920x1080"?

Re: [SOLVED] xrandr: Configure crtc 4 failed

The output is on the nvidia chip, try to explicitly set the output provider source (check "xrandr --listproviders"), https://wiki.archlinux.org/title/PRIME#Reverse_PRIME

Re: [SOLVED] xrandr: Configure crtc 4 failed

I don't quite understand what I'm supposed to do here, the wiki instructions are unclear...
Here are the commands I ran:

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x43 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 1 associated providers: 1 name:modesetting
Provider 1: id: 0x276 cap: 0x2, Sink Output crtcs: 4 outputs: 5 associated providers: 1 name:NVIDIA-G0
$ xrandr --setprovideroutputsource NVIDIA-G0 modesetting

Nothing happened.
I'm sorry. I hope I'm not wasting your time too much with my issue

Re: [SOLVED] xrandr: Configure crtc 4 failed

xrandr --setprovideroutputsource NVIDIA-G0 modesetting

is correct, but won't immediately do anything.
Can you activate the output afterwards ("xrandr --output HDMI-1-0 --mode 3840x2160")?

Re: [SOLVED] xrandr: Configure crtc 4 failed

Do you have more luck when using xf86-video-amdgpu instead of the modesetting driver?

Re: [SOLVED] xrandr: Configure crtc 4 failed

I installed the package you mentionned and rebooted.

xrandr --listproviders has different output (just the name though)

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x53 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 1 associated providers: 1 name:AMD Radeon Graphics @ pci:0000:06:00.0
Provider 1: id: 0x1f5 cap: 0x2, Sink Output crtcs: 4 outputs: 5 associated providers: 1 name:NVIDIA-G0

But apart from that, I still get the same error when I try to turn on the second monitor

$ xrandr --output HDMI-1-0 --auto
xrandr: Configure crtc 4 failed

Re: [SOLVED] xrandr: Configure crtc 4 failed

Thank you so much. This works, my monitor turns on however I'm getting a lot of input lag.
Actually, it's not quite input lag because the mouse works fine but any text field lags horribly and takes seconds to comprehend input.
Do you think this problem is related?

Should I post my Xorg log again?

Re: [SOLVED] xrandr: Configure crtc 4 failed

Do you still have xf86-video-amdgpu installed? Get rid of it again.
