Update: This issue is still not resolved on my system, and I am still stuck on pre-3.19.0-26 kernels.
However, I managed to find an unused SSD knocking around and so I installed a fresh copy of Ubuntu 14.04 to this drive, immediately dist- upgrade-ed, successfully rebooted and logged in, installed flgrx-updates and then successfully rebooted and logged in fine again. There was no sign of the freezing-up on the login screen this time. I don't know what happened; whether there was some sort of corruption as a result of the whole process, or whatever; but it looks as though I'm going to have to re-install Ubuntu and migrate all of my settings, fine- tunings, custom scripts, programs and repositories across to the new system. I'm not happy, but such is life... I'll mark this bug as closed, but I'm going to link to it in the fglrx- installer bug for future reference.

I have implemented the fix, by enabling the "Proposed" repository and also switching to "fglrx updates" but this only worsened the problem as this has caused an issue whereby my system hangs, solid, right at the login screen, when I boot into 3.19.0-26. When I boot into an earlier kernel build, the problem is not present, but no matter what I try doing; ie. uninstalling flgrx; using xserver- xorg-video-ati; reinstalling fglrx; reinstalling the new kernel; reinstalling xorg; changing the screen configuration; changing and removing monitors and their configuration; the system still hangs on booting into 3.19.0-26. I have noticed that when I boot into a working kernel however; the login screen seems to still have my old monitor configuration ie. with screen 1 to the right of screen 2, even if, upon logging in, the monitors are configured differently. I have reported this under the above summary because at least one other user has reported this same behavior (https://bugs.launchpad.net/ubuntu/+source/fglrx- installer/+bug/1479913/comments/51) and I believe that this has the same root cause as my problem. As to why the login screen keeps defaulting to my old configuration, I do not know (perhaps a problem with lightdm, or somthing), but the only option that seems left open to me at the moment is a full reinstall, which I would really like to avoid at the moment; at least until Wily comes out. Sorry to be so long winded, but this seems to be quite a serious issue and I would like it to be resolved.
