OK, good start... this seems to be a roughly 9-year-old chipset,
with a code name of "Arrandale".
However, googling "lenovo t410" from the Subject: header led me to
<https://support.lenovo.com/us/en/solutions/pd006109> which says:
Video chipsets:
* Intel HD Graphics
* 256MB NVIDIA® Quadro® NVS3100M
Does this machine actually have both Intel and Nvidia devices? If so,
it's seriously bad news, and it indicates you may have to try (and
probably fail) to use the stuff from <https://wiki.debian.org/Bumblebee>.
More likely, you'll end up disabling one of the devives at the firmware
level, and simply using the other. But I'm not a laptop user, let alone
an Optimus laptop user, so I'm only relaying what I've heard from others.
