Let's try to let nouveau turn off the dGPU with a mainline 4.17rc6 kernel, probably available as DEB packages tomorrow (21/05/2018) from http://kernel.ubuntu.com/~kernel-ppa/mainline/. See this PR: https://lkml.org/lkml/2018/5/18/159
It includes an ACPI fix critical for Optimus laptops (making the acpi_osi and acpi_rev_override workarounds obsolete). This may not be enough to get a stable system with GeForce 10xx series and nouveau just yet, but it's worth trying. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
