Question / Help QObject::connect: invalid null parameter

[Juan diego]

Hi
I just installed OBS Studio on my Fedora 23 when I try to run obs I get the following.

$ obs

I also encountered the same problem

That is an ancient version of OBS you're running there. Try upgrading to at least 19 (although running the latest would be best). Also the error message means that OBS can't connect to the X Windows system. If you've recently updated X11 (or any drivers or any systems that are dependent on it) you'll need to reboot your system.

Also if you're trying to run OBS on a 'headless' server that won't work. OBS requires X11 and OpenGL 3.2+ to work.

About having a headless system, does that mean that you need to have X11 and OpenGL 3.2.+ installed only, or that you have to have a screen actually attached to the server??
Thanks for any info on this!!

I've never tried without a screen, but I imagine that would also be required (or at least a virtual/fake screen, if you can generate one in X11).
