nouveau: hangs on boot if second monitor is present

[Jason S. Wagner]

Binary package hint: xorg

Booting to the Ubuntu Alpha 3, Beta 1 and 20100331.2 Live CDs, Ubuntu hardlocks when plymouth should transition from the bootsplash to the X session (the bootscreen stays up, appears completed but has stopped animating, while the disc reads a bit longer, before eventually hardlocking). This occurs consistently on every boot. Both of my displays are connected by DVI, but I am unsure if this makes any difference.

I workaround the issue by disconnecting my secondary display, complete the installation, boot into the OS, apply any pending updates, reboot, and install the restricted NVIDIA driver. Once installed, I can reattach the display and boot into Ubuntu without issue.

For reference, I am affected by Bug #43710, which provides a similar experience under the old 'nv' driver for Ubuntu pre-Lucid. That bug was closed as 'wontfix'. However, under that issue, I wouldn't hardlock -- I could press Ctrl+Alt+Del, and the computer would eventually reboot.

I would think this would be a blocking bug.

I forgot to mention that when plymouth starts, this error appears in textmode on my secondary display:

(process:487) GLib-WARNING **: getpwuid_r(); failed due to unknown user id (0)

Not sure if that's helpful..
