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.

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.
