After upgrading to Tails 3.13.1, I lost all control of my trackpad and keyboard. The fix was fairly simple but required mounting the Tails volume from an separate machine.
This is a problem Tails users have occasionally faced after past upgrades. Their Tails issues page has a solution under the “Tails has issues” section.
MOUNT YOUR TAILS SYSTEM PARTITION IN ANOTHER LINUX SYSTEM
- Start in another Tails or in a Linux system such as Debian or Ubuntu.
- Open GNOME Disks.
- Plug in your Tails USB stick that behaves weirdly.
- If a prompt appears to unlock the persistent volume on your Tails USB stick, click Cancel.
- Your Tails USB stick should appear in the left pane of GNOME Disks. Click on your Tails USB stick.
- In the right pane, click on the partition labeled Tails. It should be listed as Partition 1.
- Click on the button to mount the Tails partition.
- Click on the link in the right pane to open the Tails partition in the Files browser. The link should look something like /media/username/Tails.
EDIT YOUR TAILS.MODULE FILE
- In the Files browser, open the live folder. Then open the file named Tails.module with a text editor, for example, GNOME Text Editor.
- Add the line x.x.squashfs to the end of the Tails.module file. Replace x.x with the Tails version you are upgrading to.
For example, if you are upgrading to version 3.8, you would add
3.8.squashfs to the end of the Tails.module file.
Your Tails.module file should look something like this, with different version numbers:
filesystem.squashfs 3.7.squashfs 3.7.1.squashfs 3.8.squashfs
- Save the Tails.module file.
- In the sidebar of the Files browser, click on the button on the Tails label to unmount the partition. If your persistent volume shows in the sidebar, also click on the button on the persistent volume label.
- Unplug your Tails USB stick.
Your Tails should now work properly.
