The following is the different customization that i do for my arch install:

1. Disabling the beep noise :

   Simply do

   sudo rmmod pcspkr
   sudo rmmod snd_pcsp
   

   Don't worry if it gives the error snd_pcsp is not currently loaded.

   Then to prevent the modules from loading the next boot cycle create /etc/modprobe.d/nobeep.conf and add

   blacklist pcspkr
   blacklist snd_pcsp
   

   to disable loading of the moudules on further boot-ups.

2. To make sure that files of a torrent are visible in KTorrent:

   Install the geoip program using sudo pacman -S geoip
