@frdbr: what SoftExpert said, basically. We need way more info because the chance is high it is due to your specific config/machine rather than the driver, because it works for the others. I myself am running 4 FHD screens in parallel successfully with this driver version and a GTX780.

@frdbr: You do realize the given information has the same value as "It does not work"... There are a thousand different reasons for which your problem might happen: - electrical: loose connection, bad cables, etc - firmware: in some situations, bugs in the display firmware can work against a correct connection - software: bad config, bugs in the kernel, bugs in the driver, bugs in the display manager of your desktop environment - any combination of the previous reasons It is worth checking with a different kernel, turning off (unplug) the monitor, scrub the X11 config file (if you try to use Wayland with Nvidia - it's a feature, not a bug), inspect the output from xrandr, check the version of your desktop libraries, etc... And, if you like some help, share all that information with us ...

Unfortunately I am not able to use both monitors now. One of them looses signal it seems as soon as the graphical interface starts.

ok nvm I looked into this now, and the way I went about was install the 11.1 nvcodec-headers from above install cuda 12-2, then relog for them to be added to PATH so nvcc can be found by ffmpeg compile scripts install ffmpeg-full from aur, because it is on the stable 6.0 release, above ffmpeg is on 6.1 git, which is still in development afaik, so might be ok, might have bugs and/or frequent re-builds. also ffmpeg-full contains my beloved libfdk-aac, which i need so aac audio encodes don't sound superbad. takes a while to compile, otherwise you could modify the pkgbuild of another leaner ffmpeg package to just enable libfdk-aac.

now obs is recording using libfdk-aac for audio, nvenc for video x264, and it works. :) the only caveat is that you have to untick "Psycho Visual Tuning" under Settings -> Output (requires Advanced, not Simple view) because it uses Temporal AQ, which is not supported by my card (GTX780), making obs segfault cos no device for encoding is found.

I've also experienced this issue since using OBS this week, I just didn't know that it used to work with the old cards until now :) Will look into this next week, what I found so far are these, which curiously also got created in the last days of June ;)

  • "FFmpeg version of headers required to interface with Nvidias codec APIs (Version 11.1 for driver 470.xx support)" - Aur package ffnvcodec-headers-11-1 11.1.5.2-1

  • "Complete solution to record, convert and stream audio and video, built with support for NVIDIA driver version 470.xx (git version)" - Aur package ffmpeg-nvcodec-11-1-git 6.1.r111301.gf780e07149-1

@notfire: I suspect recent ffmpeg is expecting a more advanced Nvidia driver feature set; our line is barely maintained - mainly to make it still run with the latest kernels. You would probably want to recompile yourself ffmpeg, so that it picks whatever is available in the current driver headers ...

(not sure where to ask about this, so i figured i'd do it here since it's a driver issue)

i'm having an issue with OBS when trying to record using NVENC. i'm using the latest version of this driver (just made sure) and haven't had this issue before now. here's the error i'm getting:

Driver does not support the required nvenc API version. Required: 12.0 Found: 11.1

All is good on my side as well - I built all related nvidia packages.

Just a average Arch user. But thanks in advance for being the maintainer and correcting the issue :)

package updated, compiled and installed without issues for me like this. Co-Maintainers added!
