I have just installed Ubuntu Mate 16.04 and have no scroll with my touch pad, despite having enabled it in Preferences. For information, my laptop is a Lenovo ThinkPad T450. I would be grateful if someone could help me fix this issue.
Also, is it possible to change the opacity and/or colour of the horizontal grey bar at the top of the Desktop? I was able to make changes to a CSS file in Linux Mint, is there a similar method in Ubuntu Mate?
Thanks in advance
