Following worked for me to get the dgpu switched off on an xps 15 9560. 1. Purge nvidia 2. Install nvidia and do not reboot 3. Install bumblebee-nvidia 4. Set bootparameters are to acpi_rev_override=1 and i915.modeset=1
If you have tlp installed uncomment: #RUNTIME_PM_DRIVER_BLACKLIST="amdgpu nouveau nvidia radeon" Could not get optirun to work. Switching to nvidia with prime works, but switching back to intel gives a black screen with only the cursor visible. Making goto step 1. necessary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765363 Title: prime-select intel is not powering off the nvidia card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1765363/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
