Same issue for me. Nvidia is not powered off in intel mode. Cause massive battery drain, powertop shows value between 30-40 W.
Ubuntu 18.04.3, gdm3 MSI GS65 Stealth, Nvidia GTX 1070 MaxQ nvidia-prime version 0.8.8.2 Its strange that nvidia powering off in intel mode worked before on 18.04. Then I used nvidia mode for two months. Now I want to switch back to intel mode but its not working anymore. Unfortunately I don't know which update caused this, because I used nvidia mode for some time. Does this issue already have some official solution, or I have to use bbswitch? The manual bbswitch solution works for me, but I don't like it. Some notes: I tried to install nvidia driver 390, nvidia driver 430 and nvidia driver 435 from ppa and also from repository. Nvidia is not powering off in intel mode with any of them. When system booted in intel mode the /sys/kernel/debug/vgaswitcheroo directory doens't even exist... -- 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
