I stumbled into the same thing: When specifying 'nomodeset' as a kernel
parameter on an Intel i915 system (built in HD4400 graphics), I
sometimes used to get a black screen in 13.09. In 14.04, the system
would come up, but limited to 1024x768 resolution, and the monitor would
be undetected (named "built in display"). xrandr would offer no
options, and complain that:
xrandr: Failed to get size of gamma for output default
My understanding is that "nomodeset" disables KMS, which causes Xorg to
use the Vesa driver, instead of the i915 driver. The Vesa driver then
fails to detect the correct monitor resolution. Removing "nomodeset"
and running update-grub appears to fix the problem.
I don't think this deserves INVALID, since I feel that:
a) vesafb should still be able to at least detect the monitor - and ideally,
still be able to change the resolution
b) missing KMS should be clearly and accurately reported - both from xrandr,
in Xorg.0.log, and in graphics settings panel
c) lacking KMS should not disable i915 (or is this unavoidable?)

Title:
intel update 2.15.901 breaks video, reverts to vesa
Status in “xserver-xorg-video-intel” package in Ubuntu:
Confirmed
Bug description:
I upgraded today and I'm not having some video issues. xrandr hates me
and won't let me change the display setup to use my external display
and second monitor. I get this:
> xrandr: Failed to get size of gamma for output default
> Screen 0: minimum 800 x 600, current 1280 x 800, maximum 1280 x 800
> default connected 1280x800+0+0 0mm x 0mm
> 1280x800 0.0*
> 1024x768 61.0
> 960x600 0.0
> 800x600 61.0
It's not seeing any other display. I got thinking that the intel
driver might not be loading right.
Below is a lot of info, it seems like the intel driver isn't getting
setup right for the device and I'm not sure where to look from here.
Any hints/tips are appreciated.
