Dual monitors crashing Linux with NVIDIA drivers

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.
