Public bug reported:

After an upgrade last week, Unity stopped working.
Ligthdm wallpaper (with ubuntu branding on bottom) after login, mouse visible, screen goes black every a few secs, then back to wallpaper and mouse again. 
Everything worked fine before. Using Ubuntu 14.04.01 (up-to-date), Unity, Nvidia 304-updates drivers.

I installed gnome2 classic to be able to use my Pc in the meantime.
Started unity from tty1 with --log option (output attached). Multiple
compiz (opengl) - Error: FBO is incomplete: GL::FRAMEBUFFER_UNSUPPORTED
(0x8cdd) seems suspicious.

What I tried:
* renamed .compiz, .config, .gconf and .local to force the creation of new default configs. Didn't work.
* I was able to disable Framebuffer objects in opengl compiz plugin. Got Unity to start, extremely slow and unusable, with the screen going black every few seconds, then normal again, then a black region  moving from bottom to top. Enabled FBO option again.
* gnome fallback (compiz) didn't work either, only the Metacity version or gnome3 classic, so I guess it's some compiz-nvidia driver issue.
* Installed new kernel/xorg stack from hardware enablement stack (utopic versions), same issue.
* Tried nouveau drivers, worked "fine" (as fine as nouveau works on my pc, but at least Unity started normally)
* Moved to nvidia 304 drivers (no -updates), same issue there. Nvidia 173 is listed as option but won't install.
* Tried nomodeset kernel option.
* Downgraded kernel, x server and compiz  to original trusty (no trusty-updates, just trusty), same issue there.
* Reinstalled ubuntu 14.04.01, same issue after enabling nvidia driver.
* downloaded ubuntu 14.04.02, same thing.
