It looks like a misconfiguration issue (something is interfering and ldconfig finds the mesa library before NVIDIA's).
Please attach the output of the following commands: 1) ls /etc/modprobe.d/* 2) grep -i nvidia /etc/modprobe.d/* 3) grep -i mesa /etc/modprobe.d/* -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307466 Title: nvidia-prime problems with steam To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1307466/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
