I upgraded my laptop (a Dell Vostro) from Ubuntu 12.04 to 12.10, and now I'm getting a blank screen on boot. If I boot in recovery mode, I can get to a command prompt. I had a look at /var/log/Xorg.log. It failed saying "no screens found", and "No drivers available". It tried intel, vesa, modesetting and fbdev, within messages like:
'Failed to load module "intel (module does not exist)"'
Snippet from lspci -v:
Intel Corp 3rd Gen Core processor Grahics Controller (rev 09)
Subsystem: Dell Device 0562
Kernel driver in user: i915
Any help much appreciated!
