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. I'm currently using fully updated versions of nvidia driver 295.49.
