After Suspend/Resume cycle Keyboard/Mouse are not working

Support & Help Requests
1

Hi,

I have a real problem with suspend/resume not returning my pc into a workable state: My keyboard and mouse are not working anymore :angry: . Which is pretty 'sh i tty' as the only option is to use a forced power off.

Of course I tried some stuff myself, but after a week of troubleshooting I'm out of idea's.

I did manage a cumbersome workaround, it enables usb wakeup for mouse/keyboard, but that only lasts for 2+ of hours. After that, its a hard lockout.

I can remove keyboard and mouse, plug them into another USB-port and with some luck use them again. Plug them back in the original port and they are disabled again.

How can we get these basics working ?

Hi :slight_smile:
Can you share with us some dmesg after such input outage ?

Sure have a log ready, but how do I attach it ?

You can clearly see those USB disconnects :thinking:

Guy, please try this fix :

Hi olek,

atkbd.reset did not work.
usbcore.autosuspend=-1, did not work either.

PM fails to resume and then disconnects those ports.

Its getting late, I found this one. Will try tomorrow:

Here's an idea: How about a simple app that allows you to install fixes from the forum ? :thinking:

Anyway, after some hours of $!%!£$"$£"%!%% :angry: I scripted a workaround: (because I'm awesome, but don't tell anyone)

It searches all usb device's for a keyboard or mouse string, then enables them for wakeup.

Create both files below, then:
systemctl enable suspendfix.service
systemctl start suspendfix.service

/etc/systemd/system/suspendfix.service

[Unit]
Description=enables mouse & keyboard after suspend/resume cycle

[Service]
Type=oneshot
ExecStart=/etc/init.d/suspendfix.sh start
ExecStop=/etc/init.d/suspendfix.sh stop
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

/etc/init.d/suspendfix.sh

#!/bin/bash
# workaround: enables mouse & keyboard after suspend/resume cycle

wakeup_mouse_keyb(){
  OLDIFS=$IFS;IFS=$'\n'
  PRODUCTLIST=$(grep -i 'mouse\|keyboard' /sys/bus/usb/devices/*/product)
  for p in $PRODUCTLIST;do
    devicename=${p#/*product:}
    product="${p%/product*}/product"
    wakeup="${p%/product*}/power/wakeup"
    echo "$1" 2>/dev/null > $wakeup
    printf "$devicename : $(cat $wakeup)\n"
  done
  IFS=$OLDIFS
}

case "$1" in
  start)
    wakeup_mouse_keyb enabled
    ;;
  stop)
    wakeup_mouse_keyb disabled
    ;;
  restart)
    $0 stop
    sleep 1
    $0 start
    ;;

Congrats :slight_smile: Nice workaround :slight_smile:

Thanks to you others with similar HW / issue will be able to get back their devices after sleep.

Thanks @Guy :slight_smile:

You can also try to upgrade your kernel to latest - this solved many issues i got with my setups :slight_smile:

Someone else talked about this on itfoss.com forum. their solution was as follows;

sudo apt-get install --reinstall xserver-xorg-input-all

This was from a posting about 14.04, however it worked for me on 22.04 lts.
