Question / Help Fails to launch on Linux Mint 17

[phpworm]

I'm running Linux Mint 17 Cinnamon 64-bit version 2.2.16

I've used the installation instructions under the heading "Linux (Ubuntu 14.04/14.10 installation)" found on the github page.

The program icon appears in my menu, but when I open it, it immediately closes. I tried launching the program from the terminal and get the following:

$ obs

I saw in another thread someone mentioned "a GPU that supports at least OpenGL 3.3 is required for OBS (To know which OpenGL version your GPU is running, type "glxinfo | grep OpenGL" in a terminal)" I did that and get:

$ glxinfo | grep OpenGL
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Desktop 
OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.1.3
OpenGL core profile shading language version string: 1.40
OpenGL core profile context flags: (none)
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 10.1.3
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:

It appears I have OpenGL 3.0 so I'm curious, am I out of luck using OBS unless I buy a new graphics card, or is there an alternative way to resolve this issue?

If your hardware doesn't support OpenGL 3.2+ or there are no drivers with that support, then you are out of luck.

You can still try to use the xorg-edgers PPA to get the latest Mesa drivers (it could be an improvment) but read carefully the PPA description before that !

Thanks for the replies. I gave the xorg-edgers PPA a try and although it didn't resolve the issue I think it is an improvement. I've ordered a new graphics card so hopefully that works out.

might be useful for you: using recent mesa+softwareGL drivers I was able to get a very old laptop streaming via OBS.

Although as I note it takes a chunk of CPU... but if you are desperate and don't need FPS in your recording it works rather well...

Update: my new video card arrived today, installed it, and get the following output

$ glxinfo | grep OpenGL
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: Quadro K620/PCIe/SSE2

OBS now opens without any problems! Haven't tried to actually use it yet but at least it is launching. Thanks for the help.
