Public bug reported: After a suspend/resume cycle (using "deep" suspend mode), the process IRQ/51-SYNA2393 uses considerable CPU 10+%. Using the trackpad for a few seconds seems to fix the issue.
I don't normally use the trackpad while docked so it's a bit annoying to have to remember to use it just to get this problem to go away. Looks like others have hit the same issue; I found this on askubuntu: https://askubuntu.com/questions/1138642/ubuntu-18-04-drains-battery- very-fast-after-wake-up-from-a-deep-sleep ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-generic 5.4.0.33.38 ProcVersionSignature: Ubuntu 5.4.0-33.37-generic 5.4.34 Uname: Linux 5.4.0-33-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: shaun 2997 F.... pulseaudio /dev/snd/controlC0: shaun 2997 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Mon Jun 8 11:30:07 2020 InstallationDate: Installed on 2018-12-11 (544 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Release amd64 (20181017.3) MachineType: Dell Inc.
