We should try to find the way.

 

Anyway, is there no way to enable GL acceleration on windows RDP ??

Even though it could not draw on real display - we can not see that, It's OK.

It can be used for remote display or remote auto testing.



include your own osmesa library with the emulator and explicitly use osmesa (with its own osmesa "eg" layer). you now use the cpu to render gl, and push out puxels manually from the osmesa buffer. it works. on a fast enough cpu it's usable (but not brilliant).

Thanks.

Hi,

I see. Is jenkins agent configured as a windows service ? If yes, m.b. this can help:

http://jenkins-ci.361315.n4.nabble.com/DirectX-and-Jenkins-td4525448.html

IMHO this problem is not related to RDP at all, jenkins does not use RDP, it simply runs your app
and can't initialize OpenGL since service may not be allowed to be interactive. Does jenkins slave
service has "allowed interactive" enabled in service properties ?
