Cheers! I'll see what I can do there :) Thank you so much for all the

Awesome! Blacklisting the modules, then setting runtime power management to auto for everything in powertop put the power usage down to about 8W. Loading the modules back up again manually puts the power usage back up, and unloading them back down, without having to use bbswitch at all. Do you know if it's possible to, with an X session that started up without the nvidia modules loaded, then turn those modules on and use that GPU with "__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia "$@"" (the PRIME render offload in the recent drivers). I've so far not had any success :( -- 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

Do I need to apply patches myself? Or is it just the stuff I'm using (eg I only use bbswitch, on top of optimus-manager)? Sorry if this is a little asking the obvious, just had this problem for a while now and not sure how to deal with it. -- 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
[Bug 1803179]
Are these patches included in kernel 5.5.2? I blacklist nvidia modules on boot, and "echo 'OFF' | sudo tee /proc/acpi/bbswitch" (which succeeds) followed by lspci also produces a freeze on my machine. Without the call to bbswitch, the freeze does not happen, but my idle power usage is at 25-30W, instead of the ~11 that occurs if I do invoke bbswitch. I'm running Arch, with the 5.5.2 kernel. Hardware is an Intel i7-8750H and NVidia GTX 1070M, and my kernel parameters are "root=/dev/nvme0n1p5 rw add_efi_memmap initrd=intel-ucode.img initrd=initramfs-%v.img nopti intel_iommu=on iommu=on sysrq_always_enabled=1". -- 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
