** Description changed: Binary package hint: gnome-power-manager I got the latest Ubuntu installed on a Lenovo W520 with graphics set to Nvidia discrete card. The laptop freezes, however, on power-management actions, such as brightness change and sleep/wake-up. A particularly annoying problem is that the machine freezes automatically after a GUI login if I had started gnome-power-manager previously. I have to remove the gnome-power-manager settings directory in order to get back in. If I boot with acpi=off parameter to the kernel things work fine, but then again no ACPI functionality is available.
