I seem to be having an issue like this as well. I did a fresh install of 18.04 yesterday, and while the nvidia x server application states that the discrete gpu is turned off, i have a hardware light on my laptop that shows it to still be active, even though the nvidia x server settings show the integrated gpu to be in use, and there's additional fan noise and heat that typically accompanies the discrete gpu when the internal is selected.
intel i-5 2410M nvidia 550M according to nvidia, the 390 drivers are appropriate compatable with my hardware. 16.04 did not share this error, and when the discrete gpu was deactivated to run the integrated gpu, it would truly switch off. Is there another fix for this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1757180 Title: nvidia-prime can't switch off the discrete GPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1757180/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
