Ubuntu: How Drivers? Thinkpad T430u



Question:

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


Solution:1

Regarding the nvidia drivers, since the T430u has optimus technology, it's actually likely that, by default, you are only using the integrated intel graphics card.

To check, try running lsmod | grep nvidia and cat /var/log/Xorg.0.log | grep NVIDIA. If you don't get any output from those commands, you are probably not using the nvidia graphics card (or at least not with the fastest drivers). This is fine if you are not running any graphically intense programs and are satisfied with the way everything works.

You may be able to increase battery life by turning off the nvidia card using a program called bumblebee, and you can use the nvidia card to render fancy graphics using bumblebee. If you'd like more information on one of those tasks, add a comment and I can point you in the right direction.
