Xorg.0.log for first boot after fresh 12.04 install where monitor problem was experienced

This is a regression on my Radeon HD 6950 as when I installed Ubuntu 11.04 it was working however when I upgraded to 11.10 the problem started and it persists in a fresh install of Ubuntu 12.04. (Sorry I can't be more specific about when it started. If required I can boot into safe mode and pick up the version of the Radeon driver.) 

When booting during the boot splash screen before any splash is shown the monitor switches itself off for a second then turns on again but instead of showing lightdm it shows a screen of a uniform colour that appears to be related to the colour of the background on lightdm. (I noticed that the colour in Ubuntu 11.10 was a purple colour however when I upgraded to 12.04 it switched to a brownish colour, I don't know what background lightdm in 12.04 uses but I suspect that it must be similar to this brownish colour.) 

Switching to the terminal changes the uniform colour to black but does not display any text.

Might be a duplicate of bug 45018 if you are using a git snapshot of mesa.  Does disabling desktop effects fix the issue?  Please also attach your dmesg output and glxinfo output.

I'm not using a git snapshot of anything. Problem occurs with version bundled on the Ubuntu 12.04 live DVD and on the latest version in Ubuntu and the latest version available in Fedora. 

The problem happens before you see the logon screen (or during) so there are no desktop effects - at least with Ubuntu and LightDM, I'm not sure about Fedora and GDM. 

Will try and fetch info, need to install SSH I think since I can't actually see anything when the problem occurs. :P

Maybe the version that comes installed with the Ubuntu 12.04 DVD is a git version. The reported version is:

1:6.14.99~git20111219.aacbd629-0ubuntu2

And xserver-common is:

2:1.11.4-0ubuntu10
