SRU Request
While bbswitch may fail on some hybrid systems (e.g. on the desktop or when the bbswitch module fails to build), this is not a good reason to prevent the system from offloading rendering to the NVIDIA GPU.
[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. See https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310023/comments/70 |
