I just installes Linux Mint 14 Mate on my Acer Aspire V3 771G (intel i3 and nvidia GeForce GT 630M, Optimus) and I am facing a strange problem. When "showing" the login screen, the display stays black (no output at all). I can hear the "login screen ready"- sound, type in username and password (without seeing anything) and after hitting Enter the screen goes on again and the system works quite normally. Using "Automatic login" somehow works around the problem, but as it is a portable device, it doesn't solve it. My knowledge on recent graphics solutions is very limited, but for me it seems like there is an issue with the driver used before the log in. So there is no splash screen either on bootup, only textbased output with a very low resolution.
Any idea anyone? Thanks for every hint!
