It activates only after restart. I noticed it when tried to boot live image of Ubuntu 20.04.3 This problem probably appeared with kernel version 5.9 or 5.10 because with Ubuntu 20.04.2 live image (Linux 5.8) keyboard loads fine. Tried kernel 5.14 and it's still affected. I tried to recompile kernels 5.11 & 5.13 with SERIO_I8042 set as a module (as suggested in an Arch Linux bug report) and keyboard now works from the first start. In "make config" the changes are: Device Drivers -> > Generic Driver Options -> [ ] Support for uevent #may slowdown boot, needed only for U14.04 > Input device support > Keyboards -> [M] AT keyboard > Hardware I/O ports -> [M] i8042 PC Keyboard controller It changed such lines in config: CONFIG_KEYBOARD_ATKBD=m CONFIG_SERIO_I8042=m CONFIG_SERIO_LIBPS2=m References: https://bugs.archlinux.org/task/70384 https://ubuntuforums.org/showthread.php?t=2459149 https://linux.org/threads/asus-zenbook-14-um425ua-keyboard-not-respond-during-cold-boot.33738/#post-133830 P.S. Other option which helped me was a GRUB parameter "i8042.reset=1" but it had a positive effect only with kernel 5.11 --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.20 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC3: marketing-trade 807 F.... pulseaudio /dev/snd/controlC2: marketing-trade 807 F.... pulseaudio /dev/snd/controlC1: marketing-trade 807 F.... pulseaudio /dev/snd/controlC0: marketing-trade 807 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: KDE DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2021-09-01 (14 days ago) InstallationMedia: Kubuntu 20.04.2.0 LTS "Focal Fossa" - Release amd64 (20210209.1) MachineType: ASUSTeK COMPUTER INC.
