Subject: Re: Undentified issue with primus or bumblebee.
Thanks for your reply, i think i'm not suscribed tot the mailing list. I
thought there is something wrong with the Primus/Bumblebee because with 
the "testing" stretch it worked.
After i install the virtualgl package with the command "optirun -b
virtualgl" everything run.

Thank you so much for your help
