In my case the keyboard on the laptop was working on GRUB/Recovery mode but not on normal run.
I compared the kernel modules on the both runs and also did insmod/rmmod to have the same list without any difference. Then I went and compare kernel cmdline (/proc/cmdline) and update arguments one by one and found the one causing the issue! In my case it was acpi=noirq parameter to kernel boot. Removed it and now both keyboard and touchpad are working properly. ** Attachment removed: "dmi.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894012/+attachment/5521755/+files/dmi.txt ** Attachment removed: "version.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894012/+attachment/5521777/+files/version.log ** Attachment removed: "lspci-vnvn.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894012/+attachment/5521756/+files/lspci-vnvn.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894012 Title: touchpad and keyboard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1894012/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
