Have a similar problem. After debugging the prime-select code I noticed the alternatives found are both 'mesa' and this leeds the code to return either unknown" when doing a query or "Error: alternatives are not set up properly" when trying to select either nvidia or intel.
I attached the result of "/usr/bin/update-alternatives --query x86_64-linux-gnu_gl_conf" hope that it helps in getting a solution to the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310023 Title: 14.04: Nvidia Prime is unable to switch to the Nvidia card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1310023/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
