I booted into minimal non-GUI ubuntu20.04 1.4G with 5.4.22-050422 kernel I removed all possible kernel modules by repeating few times next two commands: lsmod | grep 0$ | sed 's/^\([^ ]*\).*/rmmod \1/g' > rmmods.sh source rmmods.sh

There was not shutting off laptop when using s2disk. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-5.4 in Ubuntu. https://bugs.launchpad.net/bugs/1864930 Title: brightness setting and sleep/suspend (echo mem > /sys/power/state) , s2ram and s2disk fail for 5.4.0 and s2disk fail for 5.4.22 Status in linux-5.4 package in Ubuntu: New Bug description: 1) After resuming from suspend (uswsusp/s2ram) and/or after resuming from "echo mem > /sys/power/state" there is a black screen on laptop after resume with 5.4.0-14-generic kernel only. Kernel seems to be working as CTRL+ALT+F2 and CTRL+ALT+DEL restarts laptop. A) 3 Different combinations of this distro with other kernels work well: kubunut20.04 + linux-image-5.3.0-40-generic (copied from kubuntu 19.10 from /lib/modules/5.3.0-40-generic and /boot/vmlinuz-5.3.0-40-generic) Installed from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6-rc3/ kubuntu20.04 + linux-image-unsigned-5.5.6-050506-generic is working. kubuntu20.04 + linux-image-unsigned-5.6.0-050600rc3-generic is working. B) This kernel 5.4.0-14-generic when copied manually into kubuntu 19.10 behaves the same as in 20.04 (NOT WORKING for suspend to ram) 2) setting brightness with keys on laptop keyboard does not work for this kernel 5.4.0-14-generic only Neither using this command line method marian@kubuntu2004:~/Downloads$ cat /sys/class/backlight/intel_backlight/max_brightness 255 marian@kubuntu2004:~/Downloads$ cat /sys/class/backlight/intel_backlight/max_brightness 255 marian@kubuntu2004:~/Downloads$ cat /sys/class/backlight/intel_backlight/actual_brightness 255 marian@kubuntu2004:~/Downloads$ cat /sys/class/backlight/intel_backlight/brightness 242 marian@kubuntu2004:~/Downloads$ echo 200 | sudo tee /sys/class/backlight/intel_backlight/brightness 200 marian@kubuntu2004:~/Downloads$ cat /sys/class/backlight/intel_backlight/brightness Again kernel 5.3 copied into kubuntu20.04 got working brigthness keys. However this works for all tested kernels above (including 5.4.0-14-generic) xrandr --output eDP-1 --brightness 0.8 3) after uswsusp/hibernate (s2disk) and "echo disk > /sys/power/state" do not seem to resume/thaw for those kernels: linux-image-5.4.0-14-generic, linux-image-unsigned-5.5.6-050506-generic , linux-image-unsigned-5.6.0-050600rc3-generic, on the other hand kernel linux-image-5.3.0-40-generic manually copied from kubuntu 19.10 into kubuntu 20.04 seems to be working fine when thawing/resuming from hibernation. Again I tested different combination of kernels and distros for this issue. This kernel (5.4.0-14-generic) also does not work for hibernate/resume even when copied from kubuntu20.04 into kubuntu19.10 4) Starting kubuntu without installation from daily build from 25th Feb 2020 shows the same problem for brightness setting and for black screen after resuming from sleep. http://cdimage.ubuntu.com/kubuntu/daily-live/current/ Note I always recreated imagerd in target place when copied kernels manually: update-initramfs -u -k 5.3.0-40-generic ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-14-generic 5.4.0-14.17 ProcVersionSignature: Ubuntu 5.4.0-14.17-generic 5.4.18 Uname: Linux 5.4.0-14-generic x86_64 ApportVersion: 2.20.11-0ubuntu18 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: marian 1214 F.... pulseaudio CurrentDesktop: KDE Date: Wed Feb 26 22:20:29 2020 Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 8087:0a2b Intel Corp.
