I just tried with the Vivid kernel (3.18.0) and had the same error. I
needed to restart lightdm to get things going again.

Attached is a photo of the label. I'm not sure where the description in

complexities of model numbering - in my innocence I thought it was just

Just in case this is useful I reverted the changes in that commit which affects
two files:
drivers/gpu/drm/i915/i915_drv.c and
drivers/gpu/drm/i915/intel_fb.c

version 1.20) not a PPR20E (latest version 1.70) do you think the PPR20E
BIOS will be OK?

Looking on the Toshiba site the difference seems to be a slightly

PPR20E and Pentium® M processor Ultra Low Voltage 773 for the PPR21E.
Also the spec says the PPR21E supports wireless a/b/g whereas the PPR20E

Hi there, the Toshiba site has only version 1.20-WIN BIOS [1], my
installed one reports 1.60 and trying to run the 1.20-WIN from Win XP
results in a message saying BIOS incompatible so I assume it's
preventing a downgrade. Do you have a link to a v1.70 BIOS? (This is a
Portege R200 PPR21E)

Hi there, I finally managed to do a bisect on this. It took a while

This is the end of the trail:
$ git bisect bad
24576d23976746cb52e7700c4cadbf4bc1bc3472 is the first bad commit
Thanks Joseph,
