** Description changed: This is a reintroduction of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808957 which I am experiencing with Ubuntu 20.04 fully upgraded on a Dell XPS 13 9360. This did not happen before in Ubuntu 19.04. It seems that the Dell 9360 is set to go into s2idle mode rather than deep sleep, forgoing significant power savings. I have confirmed this by suspending and then checking: sudo journalctl | grep "PM: suspend" | tail -2. If the output is PM: suspend entry (s2idle) PM: suspend exit cat /sys/power/mem_sleep showed [s2idle] deep As a temporary fix, I typed echo deep > /sys/power/mem_sleep as a root user (sudo -i). Then the output of cat /sys/power/mem_sleep was s2idle [deep] After suspending now, sudo journalctl | grep "PM: suspend" | tail -2 returns PM: suspend entry (deep) PM: suspend exit I have made this permanent by editing /etc/default/grub and replacing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep" then regenerating my grub configuration (sudo update-grub). + --- + ProblemType: Bug + AlsaVersion: Advanced Linux Sound Architecture Driver Version k5.4.0-9-generic. + ApportVersion: 2.20.11-0ubuntu15 + Architecture: amd64 + ArecordDevices: + **** List of CAPTURE Hardware Devices **** + card 0: PCH [HDA Intel PCH], device 0: ALC3246 Analog [ALC3246 Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: user 1570 F.... pulseaudio + Card0.Amixer.info: + Card hw:0 'PCH'/'HDA Intel PCH at 0xdc228000 irq 131' + Mixer name : 'Realtek ALC3246' + Components : 'HDA:10ec0256,1028075b,00100002 HDA:8086280b,80860101,00100000' + Controls : 55 + Simple ctrls : 17 + CurrentDesktop: GNOME + DistroRelease: Ubuntu 20.04 + IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig': 'iwconfig' + Lsusb: + Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub + Bus 001 Device 002: ID 8087:0a2b Intel Corp. + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + Lsusb-t: + /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M + /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M + |__ Port 3: Dev 2, If 0, Class=Wireless, Driver=btusb, 12M + |__ Port 3: Dev 2, If 1, Class=Wireless, Driver=btusb, 12M + MachineType: Dell Inc.
