Thinkpad laptop W520 series with kernel: 4.15.0-51-generic x86_64 bits: 64

Following the latest dist-update the trackpoint and it's related keys don't work after return from suspend mode. Unloading and (re-)loading of psmouse fixes the issue but is only a workaround and somewhat annoying.

TLP is installed.

Any help highly appreciated. mgw


Having to unload and reload the psmouse driver when resuming from suspend is a common problem. You can automate the process with a script though:

Create a new file in the /lib/systemd/system-sleep/ directory containing:


case $1/$2 in
    echo "Going to $2..."
    # Place your pre suspend commands here, or `exit 0` if no pre suspend action required
    modprobe -r psmouse
    echo "Waking up from $2..."
    # Place your post suspend (resume) commands here, or `exit 0` if no post suspend action required
    sleep 2
    modprobe psmouse

Make it executable:

sudo chmod a+x /lib/systemd/system-sleep/script-name

After the next reboot, the script will be active.

A script like this has worked for many people over the years. Of course your other option would be trying the previous kernel version and if it works sticking with it.

  • Txs. Another funny thing is that configure-trackpoint tells me it doesn't detect anything even though the device is working after reloading of module.

  • @mgw I've never used configure-trackpoint. You would be best served posting a new question about that problem. In the meantime click the grey check mark next to the answer if it solves the current question. Thanks. Jul 22 '19 at 15:39
  • It's "only" a workaround. Let's wait for the next kernel update. Txs for the script @WinEunuuchs2Unix

    @Photon Automatically deactivating touchpad can be done by adding instructions from: askubuntu.com/questions/751413/… into script. As for #2 you should post a new question in Ask Ubuntu. Don't forget to upvote answers you find useful :) May 23 at 13:47

    @Photon Thanks for the update. Most people don't do that. I upvoted your link because you've confirmed it works. That will help others. Aug 14 at 19:15
