Yes SSH is enabled; no I can't SSH into it. It seems to be completely dead. |

Ok. Setting "nomodeset" works. However, if I understand the nouveau driver correctly then that won't work for using the nouveau driver as it requires KMS. |

Digging a little deeper into the nouveau driver and KMS[1], I discovered that I probably need to have CONFIG_VT_HW_CONSOLE_BINDING set in the kernel config as well - which it wasn't. So that probably explains what was happening as CONFIG_HW_CONSOLE was set, so there may have been two drivers competing for fb0. |
