Comment 7 for bug 147189

You could try to revert to the old xresprobe version and see if that works. You can do that in synaptic:
- select the xresprobe package
- in the menu choose package, then force version
- in the dialog select the old (ubuntu4) xresprobe
then apply and try what sudo xresprobe intel says.

If that gives the right response you may also be able to get X running with the intel driver again.
