do you need more information?
It would be nive to know which system you are using, so it is easier to find for errors, because on your system it seems to work.

EDIT:
this line is failing:

GLXContext actx = primus.afns.glXCreateNewContext(primus.adpy, *acfgs, GLX_RGBA_TYPE, shareList, direct);

I'm using:

What is the value of acfgs prior to executing that statement, is it NULL?

What is your testing procedure? Note that you are responsible for starting secondary X, primus will not do that for you.

[karolherbst]

ahh okay, I didn't know, that I have to start a second X server. Okay, glxgears and also glxspheres are running.

seems to work, but primus should handle the start of a second X server by itself like bumblebee. Or maybe use primus just as a middleend instead of vglrun?
But I will try to do some extended tests. Should I post bug reports of application, which won't start? Or do you want to implement some functionality first?

[Lekensteyn]

@karolherbst Keep in mind that Primus is still in its very early stages of development. There is no nice integration of it at the moment.

When testing primus, I ran optirun bash in a different terminal tab. Then I went back to a free terminal tab (not in the optirun bash one!) and ran primus.

[karolherbst]

I just modified the bumblebee

KeepUnusedXServer=true
TurnCardOffAtExit=false

so the nvidia card is still loaded after an optirun call

I tried a bit to start some games and other things. Wine is not working of course.

[amonakov]

@karolherbst karolherbst, thanks for your interest. There still are some known unimplemented bits, but you can post bugreports for simple applications (mesa-demos would be very appropriate). I'm leaving for a week-long vacation.

Did you enable PRIMUS_DROPFRAMES to get 1000 fps above?

[karolherbst]

yes. I guessed, that it will leave all rendering done. via optirun I get "only" around 200 fps.
But same behaviour with glxgears.
intel => 6000 fps
opritun => 1200 fps
primusrun => 50000 fps

I am interested on this test scenario, because optirun seems to loose much fps when it comes to high fps rates. In glxspheres this effect occurs less:

intel => 220 fps
optirun => 200 fps
primusrun => 1000 fps
