Terminator and Ctrl+t in Ubuntu

For some reason I cannot understand fully there is a problem with the key <Ctrl> in Terminator. If you configure <Ctrl>+t, for example, for creating new tabs the configuration doesn’t works and is not saved. The problem is described here. The temporal solution of the problem consist in editing the Terminator configuration file in:

bash$ vim ~/.config/terminator/config

And change by hand the key binding for creating new tabs to

...
   tab_position = hidden
[keybindings]
   new_tab = t
   next_tab = Right
...

The problem seems related to Terminator using the key <Primary> instead of <Ctrl>.

Fix for the power management problem in Linux 3.10

I upgraded my Ubuntu 13.04 to the kernel 3.10 (so I can use a new USB 5Ghz WIFI card). As a consequence my computer no longer seemed to go into the «ondemand» mode and the fan was running all the time. The problem is that the Linux people has decided to relay on the intel_pstate system for power management and the old tools no longer work. You can find an explanation about the change here:

Of all the possible solutions this is the one that worked for me:
