Quoth David Niklas:
'I had a similar problem when I was using the propriety AMD
drivers several years ago. I never solved it. I just changed
drivers. My memory is hazy on the matter, but your description sounds
word for word identical to my problem.
'You might tell us what GPU driver the differing kernels are
using.
'The output of 1: lsmod 2: Reboot to old kernel 3: lsmod would
do nicely.'
The graphics modules are the same in both cases, and
non-proprietary Intel (i915 & its buddies).
