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
I don't know if it is relevant here, but I got the same response from
xrandr (about gamma), and also struggled with wrong resolutions. For me,
the cause was the 'nomodeset' kernel parameter, this (i.e. disabling
kernel modesetting) caused the i915 graphics driver to fail, and the
vesa driver to be

This thread discusses undetected ALPS touchpads on HP computers, and
seem to have some fixes (although I haven't tried any of them yet):

Although these touchpads still work by emulating a ImPS/2 mouse, I think
it might be the same problem.
A (presumably) ALPS touchpad on my HP dm-1 isn't detected either (also
on Karmic). It shows up as an ImPS/2 wheel mouse. It really, really
needs to have its sensitivity adjusted, so a solution to this would be
great.
