TLP is a pure command line tool with automated background tasks. It does not contain a GUI.

First open CLI, Terminal, Terminator or any command line.
And add the lines:

$ sudo apt-get remove laptop-mode-tools
$ sudo add-apt-repository ppa:linrunner/tlp
$ sudo apt-get update
$ sudo apt-get install tlp tlp-rdw smartmontools ethtool
$ sudo tlp start

No result when attempting to repaire battery in freezer

I read on a forum, it is possible to repaire a battery when you freeze it in the freezer.
I packed the battery in a plastic bag (zip-lock) and I put the battery in the freezer for 24 hours.
The temperature in the freezer is -18ºC.
After 24 hours I took out the battery from the freezer, I unpacked it from the plastic bag, and cleaned it.

I inserted the battery into my computer and charged it for 8 hours.
After 8 hours of charging, my battery still worked for 20 minutes as before.

The myth to repaire a battery in a freezer is not possible.
It does not work for me.

Transparent desktop text icons xubuntu 12.04

Create a file named .gtkrc-2.0 in your home directory.
Open this file in a text editor and fill it with the text:


style "xfdesktop-icon-view" {
XfdesktopIconView::label-alpha = 0

fg[NORMAL] = "#ffffff"
fg[SELECTED] = "#ffffff"
fg[ACTIVE] = "#ffffff"
}


widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"



If you want to change the text colour as well, just edit the file replacing ffffff with the desired colour's code (tip: you can use Gcolor2 to help you determine the colour code).
For the changes to take effect either log out and log in or run the command:

$ killall xfdesktop

And wait for xfdesktop to restart.
