I am trying to install Hardy Heron Ubuntu 8.04 on a old Toshiba laptop. The model number of the same is Toshiba l40-10O. First of all I this is the second time when I am trying to install this operating system. I had heard about lots of issues regarding Ubuntu compatibility on Toshiba l40-10O. The most common issue is sound and wi-fi not working. How to deal with this.
