Would you like to view the X server output to disclose the problem?
I installed Linux Mint 13 Cinnamon 64-bit edition today, with no problems. It told me to restart (fairly typical of an OS installation), so I did. However, every time I've tried to boot it up it's given me the error "Failed to start the x server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to disclose the problem?
I didn't find the right solution from the internet.
