Hi All. New user here. I've encountered 2 problems installing Mint 14 Cinnamon, one of which I "solved," though the solution brought up another issue. The machine in question is an Asus G55VW with a Nvidia GTX 660M, Intel i7-3610QM, 12 GB RAM, Athereos AR9485 Wireless, Atheros AR 8151 GB ethernet.
1. Looping login after fresh install. Once a username/pass is entered at the login screen, the X server starts then crashes, bringing you back to the login screen. Log file ~/.xsession.errors showed a "segmentation fault," which did not help me much. X server was using the video driver Nouveau. What I eventually discovered after hours of searching log files was that the problem seemed totally unrelated to the X server: if I was connected to the internet by either lan or wireless, the x server crashed. If I ctrl-alt-F1'd to a terminal and used 'fskill block all', I would be taken to the desktop. I replicated this behaviour numerous times on both Cinnamon and Mint KDE. I always had to switch to the console and block lan/wireless before I could log in.
2. Once I installed the Nvidia proprietary drivers, there were no login problems at boot. Using autologin, it would boot straight to the desktop. The problem now is that I can never get to the login screen. If I kill X server or log out, x server starts, crashes, goes to the full screen terminal and tries again to start x server. It tries this three times before showing a text box saying, "Failed to start the X server...." The error message is "Fatal server error: no screens found." The Xorg.0.log expands on this with the error message "Screen(s) found, but none have a usable configuration." I eventually reach the fullscreen terminal where I am informed that X server is disabled until configuration is fixed. The machine has to be rebooted to reach the desktop.
Question: if my configuration is "bad," why does the computer boot beautifully to the desktop? The only time the configuration seems to be bad is when I logout or the X server is otherwise killed..
I've spent three days reading logfiles, googling error messages, etc. (good learning experience) but I am now stumped. I've tried other Nvidia drivers. Can anyone offer any suggestions?
