I have an i7 8750H with a GTX 1050 Mobile. I applied these two patches on top of Linus' tree. After I switched all "power/control" to "auto", everything works now. Card powers down, suspend/resume works. Thank you for figuring this out. Before this I was getting lockups with bbswitch/acpi_call during boot. I had to do crazy workarounds to get away with this during early boot and suspend/resume. Those days are gone now! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803179 Title: System does not reliably come out of suspend To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1803179/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
