Bug Description
I've been testing the Ubuntu GNOME Vivid daily images in anticipation of Alpha 2 and I noticed that with this specific hardware I get no graphics at all other than a blank screen (see attached photo):
AMD Sempron Processor LE-1250 @ 2.2 GHz
nVidia C61 [GeForce 7025 / nForce 630a] (rev a2)
nVidia MCP61 High Definition Audio (rev a2)
nVidia MCP61 Ethernet (rev a2)
2GB DDR2 RAM
In fact I never even get as far as the screen offering to Try or Install, but I can enter the Advanced Boot Options screen and select either Try or Install from there, but with both options I still get the same blank screen.
Further testing reveals the same results with Ubuntu and Ubuntu GNOME but I found that both the Xubuntu and Lubuntu images will boot properly on this box so I installed Lubuntu and then installed the ubuntu-desktop, ubuntu-
After doing so I found that the Unity, GNOME Shell, Gnome Classic, and Flashback w/Compiz sessions produce broken graphics just as the Ubuntu GNOME and Ubuntu live images do. So basically Compiz and Mutter both fail to display any usable UI. OTOH both the Lubuntu and Flashback w/Metacity sessions work just fine.
I next opened the Additional drivers UI and chose nvidia-304.125 (current) and all DE's perform quite well with the proprietary drivers so I deduced that nouveau might be the culprit.
The last known working Ubuntu and Ubuntu GNOME live images are 14.04.1. I hadn't tried Utopic on this box yet but it's also a fail. I'll try the proposed 14.04.2 images ASAP (probably after Vivid Alpha 2 is released).
But I see no point in trying to fix this for Utopic (or even 14.04.2 if it's effected) because of the 9 month life-cycle for Utopic and the continued availability of the 14.04.1 images. In fact I'd be cool with this not being fixed until 16.04 as long as it's documented so people know what versions will and will not work.
I'm probably forgetting something but that's all I can think of ATM. Sorry in advance if I did this totally wrong.
### Additional workaround and debug info ###
The focus of this bug report is limited to screen corruption and X-freezes that either prevent the installation of Ubuntu (or other flavors) and/or booting the installed system even long enough to enable the third party nvidia driver. There are almost certainly other instances of screen corruption and hard (or soft) lockups that may also be related to the nouveau driver but those are beyond the scope of this specific bug report.
To workaround this bug, or to see if you're affected by it you can boot using this boot parameter:
nouveau.
You'll find general instructions for using custom boot parameters at these links:

In addition to what's said at the latter link about temporarily adding a kernel boot parameter to an installed system; after using the arrow keys to navigate to the line beginning with "linux /boot" you'll notice that line ends with "quiet splash $vt_handoff". The boot parameter belongs between the "quiet splash" and "$vt_handoff" like this:
quiet splash nouveau.

Here's what Ubuntu GNOME Vivid 20150119 i386 boots to when it should display Try or Install. I was able to enter the advanced boot menu and run check disc for defects so I know it's not just a bad burn.
