I have a Lenovo S540 with a Radeon HD8670M and installed Ubuntu 14.04, after reading this bug I was convinced I had the same problem. Booting with "nomodeset" in the boot options enabled unity to load with all kernels. I installed kernel 3.14.1-031401-generic _and_ fglrx and now I'm able to boot into unity. Without fglrx still a blank screen, I can't attach the logs but it appeared that X tried to load fglrx when it wasn't installed..
Hope it helps.. :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1264835 Title: Low graphic mode Status in “linux” package in Ubuntu: Incomplete Bug description: After installation process of 14.04 and 13.10 I get "low graphic mode" prompt but actually with no low mode activated ( nothing happening).
