Hello,

I have a problem which I don't find a solution for it. And it only
happens when the charger is disconnected. The problem is the fallowing :

- When the charger is connected the OS is fast. 
- But, when it isn't, then Ubuntu becomes impossible to use because of it slowness (taking up to 3 minutos to open an application if the mouse is not on top of another application).

A workaround that I've found is to disable pm-powersave by doing : "sudo
pm-powersave false". But this workaround causes 2 problems :

1 - It need to be loaded every time I boot the laptop
2 - If pm-powersave is set to false then the laptop won't Suspend.

Another thing : My laptop has an nVidia GPU and I am using the Nouveau
driver. If I boot the computer with the "nomodeset" option set in the
kernel, then I will have a small resolution, no visual effects, but
there will be no slow down problem

Best Regards,
Luis Da Costa
