[SOLVED] No keyboard and mouse after suspend (Plasma/Wayland)

Hi there,
I am using Plasma with Wayland on an Dell Latitude 3340 Laptop.
My problem is, that after suspend, my keyboard and mouse get unresponsive.

cat /proc/bus/input/devices

gives

I: Bus=0011 Vendor=0001 Product=0001 Version=ab83
N: Name="AT Translated Set 2 keyboard"
P: Phys=isa0060/serio0/input0
S: Sysfs=/devices/platform/i8042/serio0/input/input4
U: Uniq=

B: KEY=1100f02902000 8380307cf910f001 feffffdfffefffff fffffffffffffffe
B: MSC=10
B: LED=7

I tried it with Xfce4 and Xorg, and all works well. But with Plasma and Wayland, my keayboard is dead after resume.

I do not get what the problem could be.....

$ systemctl suspend
$ journalctl --system --boot=0 --priority=3 | tail --lines=50

gives

Re: [SOLVED] No keyboard and mouse after suspend (Plasma/Wayland)

I actually on Fedora, and I have a Dell XPS with Wayland+KDE, and I started getting the same issue as you today.

I got it fixed by adding this to my GRUB command line arguments.
`i8042=dumbkbd=1`

At first, I had thought it might be related to the `i8042: Warning: Keylock active` which I also had, so I tried adding `i8042.unlock=1` to the GRUB command line arguments, but that didn't fix it.

I'm not sure if I lose any features using `dumbkbd=1` but everything seems to work fine so far.

Re: [SOLVED] No keyboard and mouse after suspend (Plasma/Wayland)

Thank you so much! This works for me!!!

As I use systemd-boot, I had to change my

$ sudo nano /boot/loader/entries/arch.conf

to something like:

title    Arch Linux
linux    /vmlinuz-linux
initrd   /initramfs-linux.img
options root=LABEL=arch rw  i8042.dumbkbd=1

Thanks again for setting up a user account and answering me!
Made my day!
