[Bug 668017] [NEW] freeze when starting X (intel) from the recovery console

[Roman Gröger]

Public bug reported:

The screen goes blank when I start the X server from the recovery console. The computer is SONY VAIO VPCY2 with the integrated Intel graphics (i915). If I boot into the recovery console and use the intel driver on xorg.conf, the X windows do not even start. The screen goes blank and the computer freezes. I saw some complaints when booting about intel_agp:
  "unknown symbol intel_agp_enabled (err -16)"
  "gave up waiting for init of module intel_agp"
  "unknown symbol intel_max_stolen (err -16)"
Somebody on the web suggested to blacklist intel_agp by adding a line
  blacklist intel_agp
in /etc/modprobe.d/blacklist.conf
and updating the initramfs by
  sudo update-initramfs -u
This removed the error messages about intel_agp but the computer still freezes. I am attaching Xorg.0.log that was generated during this freeze.
