Unity tweak tools

The following settings are my personal favorites.

The settings are not risky.

Generally transparency is disabled, menu bar (launcher) is placed at the bottom of the screen and mouse features are disabled (like snapping, hot corners etc) since i dont use the mouse.

sudo apt-get install unity-tweak-tool

Do the following configurations:

  1. at Unity->Launcher menu:
    1. disable autohide
    2. disable transparency
    3. disable “Show Desktop Icon”
    4. set position to “bottom”

Find best Wifi channel

  1. Download inSSIDer (official site here)
  2. For each possible valid value as channel of your Access point:
    1. Configure your accesspoint to use that channel
    2. run inSSIDer and note the link score of your WiFi
  3. Configure your access point to use the channel with the highest link score.

Optimally your link score should be 100.


  1. By using the same channel as the other WiFis you decrease speed but also decrease intermissions, thus network becomes more stable.
  2. By using channels very close (but not equal) to other WiFis you increase speed but also increase intermission (thus network becomes less stable)
