Bug#564318: xserver-xorg-video-intel: Can't switch VT's when KMS is enabled

[Vasilis Vasaitis <v.vasaitis@sms.ed.ac.uk>]

  I'm having this problem too.

  The computer is a ThinkPad X40 laptop, with the 855GM graphics chip.
With the current version of the intel driver package (2.9.1-2), once
kdm starts, if I try to switch to another console with Ctrl-Alt-F? the
screen simply freezes. Note that in my case it doesn't unfreeze again
when I try to go back with Alt-F7; the only way out is to reboot.

  This behaviour is consistent regardless of the way the console has
been setup, i.e. it appears:

  - when the console is running the vesa framebuffer
  - when the console is running the 80x25 text mode
  - when the console is running the KMS-enabled, i915-module-provided
    graphics mode (!)

  Oh, and I'm running kernel 2.6.32.1, which I have compiled myself.

  The only way I managed to solve this was by downgrading to 2.9.1-1;
which required downgrading xserver-xorg-core too; which in turn caused
me to lose all input devices until I downgraded the
xserver-xorg-input-* packages too. Note that with the downgraded
versions I'm still running everything (both console and X) with KMS
and it's working like a charm.

  On another computer with the 945G graphics chip, I'm having no
problems whatsoever with the newer versions of the aforementioned
packages.

  Ideas?

Thanks,
Vasilis
