I installed at first Ubuntu 12.04 , then 12.10 on a fresh built custom PC with a Intel Core i7 3770, OCZ Vertex 4 SSD and 16GB DDR3-1600 Ram on a ASRock Z77E-ITX Mainboard. After both installations I ended up randomly in this "low graphics mode".

Entering "sudo service lightdm restart" after login in the text console worked, but naturally this isn't a very comfortable solution

So I tried the workaround from Michael (starkpc) in post #16 and it did work for me – even with a sleep value of only 1. For now I'm good I suppose...
