Mouse Sensitivity Issues

Hello everyone, After having trouble with LVM and Encryption on Trisquel 9, I installed Trisquel 8 with LVM and Encryption, then changed sources to 'etiona' and did:

sudo apt update
sudp apt upgrade
sudo apt dist-upgrade

I repeated these several times and had to install a few dependencies. I believe it was called software-common-properties.

I'm currently having very low sensitivity on my mouse and changing acceleration and speed in settings didn't much help. I must say that it was working quite well before I had updated to Trisquel 9. Did I delete an important package during update?

Thanks!
