1) 'Open Terminal' on right click
2) Sound: actually my card (Realtek ALC 653, 6-ch Audio CODEC) was
detected but no sound came (checked for loose wire, muted volume,
under alsa-mixer etc). I tried to run a script for installing audio
drivers from the Linux Drivers given in my mobo CD (Asus A8V-MX). But
now even my sound card is not detected. And the /dev/dsp file is also
missing.
