For me it happens on an Nvidia GeForce 7900 GS and only since 12.04 final (fresh install yesterday ,fully up to date with the 295.40 Nvidia proprietaries). My monitor is an ASUS MS238. While at the jittery login screen, the monitor reports 1920x1080@25Hz. Once logged in the monitor reports 1920x1080@60Hz. Tried multiple xorg.conf combinations, but it always seems to be 25Hz at the login screen. With 12.04 on my much newer Acer AS5750 laptop, the problem is non-existent.
