The applet not working after installing the proprietary driver Ati or ati-driver-installer-10-4-x86.x86_64.run.
With the driver by default is Ok.

Regards.

Hi,

Quickly I comment you that:

- No.. with the default ATI driver the brightness applet does not work too. I have not installed the privative ATI driver.
- It happens with desktop effects enabled and also if it are disabled.
- I also cannot hover and use the middle roll on the mouse to raise/lower brightness.. Still worse: Just hovering over the brightness applet makes the whole computer to crash (it freezes). I then have to take off the power wire (the laptop has not restart button).
- Perhaps a hint: If I try to change screen brightness directly at gnome-power-preferences... Same thing, the whole computer also freezes just hovering the cursor over its respective slide.

The following message does appear when trying to fill a bug using ubuntu-bug from a terminal, regarding gnome-power-preferences:

~$ ubuntu-bug gnome-power-preferences
Gtk-Message: Failed to load module "pk-gtk-module": libpk-gtk-module.so: no se puede abrír el archivo de objeto compartido: No existe el fichero ó directorio

The bug it's that the whole SYSTEM FREEZES when I try to adjust screen brightness by dragging the slider at gnome-power-preferences in System > Preferences.

Also I can't adjust the brightness of the monitor by using the brightness applet, at all. It also freezes the PC if I try to use the applet slider or perhaps even if I just hover over there and try to use the middle roll on the mouse.
