If I run prime-select nvidia, then log off, I get a black screen with a blinking white cursor in the top left. sometimes, I get a dialog saying graphics, input etc. devices weren’t found, and I could configure them. From there, I can’t get anywhere, and have to press the power button (which initiates, and completes a shutdown). Upon restarting, prime-select query returns nvidia. If I do prime-select intel, then logging out makes it stick, as expected.
I also noticed that if I install bumblebee, then rebooting doesn’t work either, and optirun etc. doesn’t work at all. If I purge bumblebee, then prime-select nvidia works after a reboot.
A couple of months back, optirun worked as expected.
I’ve run the following:
apt-get purge '.*nvidia.*' 'bumblebee.*' '.*primus.' apt-get install nvidia-378 nvidia-prime nvidia-settings apt-get install cuda
I’d appreciate any help in tracking down the issue. System details are:
- Dell Precision 5510, with intel i915, and Quadro M1000M card with the quadro feeding through the intel.
- Ubuntu 16.10
- kernel 4.10.6
