Hi all. I recently purchased a T430 with the NVS 5400M 2GB discrete GPU with the intention of using it as my dev machine for CUDA work. Unfortuneately, when I set the machine to boot with Optimus OS check disabled and the GPU set to Discrete I cannot boot into linux. I have tried installing with the inbuilt graphics, instlaling the NVidia binary blob, then changing over but the system just hangs while booting. I have tried booting into a live CD with the discrete option and it has failed to boot, and have tried a text-based installation and it still fails. I have been using Ubuntu 12.04 x64 default, alternate, and even Xubuntu. I have come to understand that this distro was supported (or at least proven to work) on this machine, but I haven't achieved this with the NVidia GPU.
If anybody has any suggestions for this I would greatly appreciate it. Thank you.
Solved! Go to Solution.

I have T430 and was interested in the issues you were having and set my BIOS settings to what you stated and tried to load my Ubuntu 12.04 LTE x64 ( its on duel boot with Windows 7) and got a screen that was lined/black/purple/fuzzy and just frozen. I Know for a fact that if I revert the settings that I will be able to load into Ubuntu 12.04. As a side note windows 7 x64 bit loads fine with the BIOS setting you said. I know this isn't really a solution but a affirmation of your problem but I will be looking into it and I will get back to you with any fix or work around I can find.

Just an FYI/Me too from a W530 owner. This problem also exists on the W530 when choosing the 'Discrete' option when running Ubuntu 12.04 with and without the Bumbelbee package installed.
When using Discrete, I get a very low-res GRUB screen. I select default and the screen goes purple (normal boot); the Ubuntu boot logo does not come on and eventually the HDD LED goes off. Knowing that the next thing to do would be to enter my password, I do that, but nothing happens. No HDD activity; nothing.
I've got to hold the power button down to turn it off. When I turn it back on, it looks like it is booting, Thinklight & keyboard light up and then it shuts down (No Lenovo POST screen) and starts back up normally.
