after updating to 14.01 version my touch pad is not working. im using hp pavilion 17. my laptop is brand new, it came with 12.04 pre-installed ubuntu version. my wired usb mouse do work but the right click on it does not work. moreover, when i scroll up or down using wheel button on mouse the mose functions stop at all, then i have to enable mouse again from the terminal. since i am not that much tech savvy and also new to ubuntu kindly help me.
You can detect if you have some library problems by opening the terminal (CtrlAltt) and typing:
sudo apt-get check
If you get an error message (if not see the link below), you can solve it using:
sudo apt-get -f install
This will repair broken dependencies, that could be the problem.
If this doesn't solve the issue, you could try this solution (it requires more work):
Hope you can solve it!
