Optimus IS working here, no problem at all.

I will try this maybe tonight when I will have more time to spare. I too would be interested in gaining 20-30% battery life! But, then again, I wouldn't want to have to reboot to be able to use the dGPU (I use it for blender3d). > for me it's around 7-8W intel only and around 11W when using your workaround. > But again your solution is just not really disabling the nvidia card, > instead it's more like just not using it and let it stay in idle mode with > limited PM. Yes, and no... as far as I can see from my tests, it is not staying in idle mode, it is being fully powered down by the kernel when not in use, and fully powered up again when I use optirun. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-390 in Ubuntu. https://bugs.launchpad.net/bugs/1803179 Title: System does not reliably come out of suspend Status in Linux: Incomplete Status in linux package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-390 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-410 package in Ubuntu: Confirmed Bug description: Dell XPS 15 (9750); it might eventually manage to suspend when the lid is closed, but more often than not will not wake up again when the lid is opened. Waking up using the power button often results in a system that is apparently frozen (graphics displayed are the last on screen before suspend, clock seconds do not change) System is unresponsive to the keyboard at that time (can't switch to a VT or otherwise interact with the system other than holding the power button for a few seconds to shut it down).
