Re: Lenovo T510 Quadro NVS 3100M failure ...
I have a (new) T510 with Nvidia optimus 3100M and i was having the problems described above. The solution was to grab the latest drivers - 260.19.36 at time of writing but also to go into the bios and disable optimus. One i has done that i was up and running.
just to be clear you can definitely disable optimus in the t510 bios
im running ubuntu 10.10 32-bit
