Interesting ... triggered by "[ 0.278602] i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp", I just tried i8042.nopnp as only option in GRUB, and that works too: keyboard works immediatly.
And that message was already in the first dmesg ... so the i8042 driver already something was fishy, and hinted what I should do ... ? sander@zwart2204:~$ sudo dmesg | grep i8042 [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-5.15.0-33-generic root=UUID=1e423543-e174-4d68-9250-1707c248963c ro quiet splash i8042.nopnp vt.handoff=7 [ 0.024392] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-5.15.0-33-generic root=UUID=1e423543-e174-4d68-9250-1707c248963c ro quiet splash i8042.nopnp vt.handoff=7 [ 0.278664] i8042: PNP detection disabled [ 0.297102] serio: i8042 KBD port at 0x60,0x64 irq 1 [ 0.297106] serio: i8042 AUX port at 0x60,0x64 irq 12 [ 2.199442] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input8 [ 2.803523] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input17 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1976396 Title: laptop keyboard not working for about 30 seconds after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1976396/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
