Hi I recently installed Ubuntu 13.04 onto my Lenovo ThinkPad T430u and as far as I can tell it's all working but I would like to somehow confirm that all the drivers are functioning correctly, particularly the drivers for the nvidia 620m.

I also have a small issue where hibernate is greyed out and cannot be selected in the power management section of the settings panel.

any help would be appreciated, If you can't help please bump
