Hi there!
Just try plugging in the mouse and see what happens. Regarding the touchpad,
have you checked out the configuration options in system settings?
There is also a user unfriendly but much more encompassing way to fiddle with
the various parameters. This involves opening 2 terminal windows.
In one of them read the manual page for the driverman synaptics
In the other first make backup of your old settingssynclient >
~/original-touchpad-settings
(The tilde (~) means your home folder, i.e. /home/YOURUSERNAME/)
Then input synclient
This will list the value of some variables. You can find out what they mean
from the other window.
You can then change the values withsynclient variable=new value
If things go wonky, you can always check the file
~/original-touchpad-settings for the original values.
