whl2: 1) Regarding the use of non-default kernel parameter: acpi_backlight=vendor
Is this required for something? If you boot without this parameter does this change anything? 2) If you remove the nvidia proprietary drivers, does this provide a WORKAROUND? 3) If you remove the 3rd party software "asus-fan" and "nbfc" is this still reproducible? ** Tags added: latest-bios-304 ** Attachment removed: "lspci-vnvn.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1775717/+attachment/5149995/+files/lspci-vnvn.log ** Tags added: regression-release ** Description changed: After upgrading from Ubuntu 16.04 to 18.04, I've noticed that CPU and GPU fans suddenly go full throttle. It doesn't seem to depend on temperature, could happen when 32 °C reported, sometimes the laptop can work for day or two without this issue, but eventually it happens. The only way to stop fans is to power off the laptop, power on (fans go 100% at this point again), power off during BIOS splash screen and power on again. Seems to happen more often after waking up from a sleep. Things tried: Upgrading BIOS to latest available on ASUS site to the date of writing. No change. asus-fan kernel module (https://github.com/daringer/asus-fan). Detects both fans and shows correct speed in /sys/class/hwmon/*/fan{1,2}*, but does not seem to control it and does not prevent going full throttle. 4.17.0 kernel from Ubuntu mainline builds. Doesn't seem to affect the issue. Userspace fan control software (https://github.com/hirschmann/nbfc). Can control speed of both fans to the point where they go full throttle, after that has no effect on them. - - System info: - - $ lsb_release -rd - Description: Ubuntu 18.04 LTS - Release: 18.04 - - $ cat /proc/version - Linux version 4.17.0-041700-generic (kernel@kathleen) (gcc version 7.3.0 (Ubuntu 7.3.0-20ubuntu1)) #201806041953 SMP Mon Jun 4 19:55:25 UTC 2018 - --- - ProblemType: Bug - ApportVersion: 2.20.9-0ubuntu7.2 - Architecture: amd64 - CurrentDesktop: ubuntu:GNOME - DistroRelease: Ubuntu 18.04 - InstallationDate: Installed on 2014-10-20 (1332 days ago) - InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64+mac (20140722.2) - NonfreeKernelModules: nvidia_modeset nvidia wl - Package: linux (not installed) - Tags: bionic - Uname: Linux 4.17.0-041700-generic x86_64 - UnreportableReason: The running kernel is not an Ubuntu kernel - UpgradeStatus: No upgrade log present (probably fresh install) - UserGroups: adm audio cdrom dip docker lpadmin plugdev sambashare sudo tty video - _MarkForUpload: True - --- + --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC1: whale 3068 F.... pulseaudio - /dev/snd/controlC0: whale 3068 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC1: whale 3068 F.... pulseaudio + /dev/snd/controlC0: whale 3068 F.... pulseaudio CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=ada9b595-bbf2-40a3-8575-5908492bb969 InstallationDate: Installed on 2014-10-20 (1333 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64+mac (20140722.2) MachineType: ASUSTeK COMPUTER INC.
