https://bugzilla.kernel.org/show_bug.cgi?id=201203 Bug ID: 201203 Summary: [nouveau] Nvidia chip stops turning off on resume from suspend after AC state change Product: Drivers Version: 2.5 Kernel Version: 4.12 - 4.18 opensuse kernel Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: srid@xxxxxxxxx Regression: No Originally reported at https://bugzilla.opensuse.org/show_bug.cgi?id=1109376 Sometimes nvidia chips stops turning off, draining laptop's battery. Steps to reproduce: 1. Boot laptop while on battery power Nouveau turns off the nvidia chip if it is not used 2. Plug the AC adapter The nvidia chip is still unpowered if nobody is using it 3. Suspend computer to ram 4. Resume The nvidia chip is always powered on regardless of if it is used or not. I have tried this with linux 4.18 (including vanilla build) from opensuse's kernel:stable repo, problem still persists. Laptop would resume correctly if you don't change AC state while OS is running. kernel log contains no warnings or errors related to nouveau or DRM subsytem. Laptop used to work fine with linux 4.4 System Information Manufacturer: ASUSTeK Computer Inc.
