Kyle Auble, this bug was reported a while ago and there hasn't been any 
activity in it recently. We were wondering if this is still an issue? If so, :
+ Did this issue not occur in prior Ubuntu releases?
+ As well, could you please test upstream kernel 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc7-quantal/ following 
https://wiki.ubuntu.com/KernelMainlineBuilds ? Once you've tested the upstream 
kernel, please comment on which kernel version specifically you tested and 
remove the tag:
needs-upstream-testing

This can be done by clicking on the yellow pencil icon next to the tag located 
at the bottom of the bug description and deleting the text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why 
specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

Please let us know your results. Thank you for your understanding.

+ WORKAROUND: If I boot my computer from battery power alone without AC,
+ my GPU & the Ubuntu splash screen load on startup.
+ 
  I've been running Ubuntu 12.04 for a few weeks now, I really like it,
  but from the beginning, I had the issue where the proprietary nvidia
  driver installs but fails to load (confirmed from the commandline,
  jockey, and the nvidia-dashboard). Over time, I've noticed that
  sometimes when I power on, the driver does load and I can enter a full
  unity session without problems, but other times, I fall back onto the
  VESA driver and a unity 2d session. On a whim, I finally copied logs
  from both successful and unsuccessful boots, cut out the times, ran a
  diff on them, and noticed a pattern in the kernel messages.
  
  I'm filing this bug after a successful boot so I've also attached copies
  of dmesg, Xorg, & jockey logs from an unsuccessful boot. The first thing
  I saw in the logs was a timing discrepancy between the two boots, most
  of which is due to GPE storms. I've checked other logs and there's not a
  clear relation, I've had successful boots with them and unsuccessful
  ones without them. I do still wonder if they may be involved because it
  seems I'm a little luckier if I turn off and unplug any peripherals
  before booting.
  
  But around line 325 in my dmesg logs, at the last step that mentions my
  GPU (pci device 0000:01:00.0), there is consistently at most a 6 ms
  delay for successful boots, but a 30 ms one for unsuccessful ones. Also,
  on all dmesg logs from successful boots, around line 610, the message
  "Boot video device" is recorded for the PCI number of my GPU, but for
  every fallback, the message never appears. That's why I'm thinking it's
  a kernel issue because the earliest mention of a specific driver module
  doesn't occur until later in the log. My computer also suspended fine
  last time I tried it under the nvidia module, but my monitor never turns
  back on if I suspend while using the VESA driver. I don't know if it's
  the 3D support or what, but not having the GPU seems to cause a lot of
  other issues.
  
  If you need me to attach any more information, try anything else, or
  report something upstream, just let me know. The GPU is an on-board
  GeForce 8400M GT, and the processor is an Intel Core 2 Duo T7250. My
  setup's a little quirky because I'm using a 32-bit version of Ubuntu
  although I have a 64-bit processor, but I'm currently using fully
  updated versions of nvidia driver 295.49 and kernel 3.2.0-24.
