My T410 has a NVIDIA graphics card (NVS 3100M).
My BIOS configuration looks like this:
- NVIDIA Optimus is disabled in
- "Discrete" mode on
- Internal Intel card deactivated
My X crashed when trying to activate both Dell U2410 monitors connected using DVI to the docking station.
The solution was to disable DDC/CI on the monitors: Menu -> Other settings -> DDC/CI disable
Note that you shouldn't disable DDC/CI if you don't have any issues with your displays.
