I have installed ubuntu 14.04 on my Toshiba laptop, installed many applications and running smmothly with KDE/Unity/Razor Qt/Mate desktops. Recently I applied a software update, which downloaded about 900 MB of packages, and on rebooting I found that the installation was upgraded to 14.04.03 Trusty (Jessie/Sid). I have the installed softwares intact and working fine. But I could not use external (USB) mouse. Also network is not working. Please guide me Thanking in anticipation, arulamudhu
