[Impact] * This problem makes it impossible to use the NVIDIA GPU on hybrid systems with Intel+NVIDIA GPUs when bbswitch is not available (i.e. when it fails to load). [Test Case] * Make sure to be using a hybrid system with Intel+NVIDIA GPUs. * Check that bbswitch is not available. You can do so by posting output of the following command: test -e /proc/acpi/bbswitch && echo true || echo false * Make sure that the gpu-manager is not disabled (only necessary if you disabled it manually). * Install ubuntu-drivers-common from trusty-proposed. * Remove all fglrx and nvidia drivers (keep the nvidia-common and the nvidia-prime packages): sudo apt-get --purge remove nvidia-331 sudo apt-get --purge remove nvidia-331 sudo apt-get --purge remove fglrx sudo apt-get --purge remove fglrx-updates * Restart the system. * Install the nvidia binary driver, reboot, and check that the binary driver is enabled (attach your /var/log/gpu-manager.log) - Expected: the NVIDIA discrete GPU is enabled. - Bad behavior: the system switches back to the intel driver and the discrete GPU is not used, despite the fact that the system was configured properly. [Regression Potential] * Low. Systems that currently work will keep working as usual, the ones that currently fail should finally work. [Other Info] * N/A ----------- The gpu-manager should allow RandR offloading without bbswitch. This would allow desktop systems to make use of offloading even when bbswitch is not supported. Also, nvidia-settings should not complain in such scenarios.
