Run export LIBGL_ALWAYS_INDIRECT=1 in WSL to force rendering to happen on the Windows side of things.

I've got Ubuntu 16.04 running in Windows 10 16251.0 as a Linux subsystem, and I've got Xming-mesa 6.9.0.31 installed.

I launch Xming using Xming :0 -multiwindow -clipboard

Then in my Ubuntu bash shell I type export DISPLAY=:0 and I can launch graphical applications in Xming.

However, I do not get accelerated graphics, so when I launch an editor (e.g. sudo spyder3), I have to deal with the jerky scrolling and such that you get without acceleration.

How do I fix this? I'm sure my video card (AMD RX480 latest drivers) supports OpenGL, but for some reason I'm not activating it correctly.

export LIBGL_ALWAYS_INDIRECT=1 export DISPLAY=:0 sudo spyder3 No change :(

@geofurb What if you try it with glxgears?

How would I do that?

glxgears isn't realted to spyder3, I want you to see if LIBGL_ALWAYS_INDIRECT impacts glxgears.

~1300FPS, but it jolts every so often. (Unless that's part of the intended behavior?)

What's the difference when LIBGL_ALWAYS_INDIRECT is and isn't set.

Similar performance after executing export LIBGL_ALWAYS_INDIRECT=0

Did you unset LIBGL_ALWAYS_INDIRECT before running it the first time?

Negative; confirmed with export -p that LIBGL_ALWAYS_INDIRECT was set for the first run and unset for the second run.

I don't know, then. Sorry.

What's the reasoning there?

@geofurb Oh I just remembered, it's an option in XMing as well, or at least VcXsrv has it.

So setting LIBGL_ALWAYS_INDIRECT=0 doesn't refert the framerate from glxgears to software accelerated speeds; HOWEVER, rebooting the machine restores it to software acceleration, and you get ~60fps instead of ~1300fps. What's going on that Spyder isn't benefiting from this graphical acceleration?

Would XDMCP offer better performance or worse, since I'm rendering on the Windows computer?

When I use this with -wgl it makes glxgears far slower. The only smooth animation is no -wgl and no LIBGL_ALWAYS_INDIRECT.

@user541686 I had to do the same. See this related question for more info: superuser.com/questions/1487555/…
