I have just built a new system based on a Gigabyte GA-Z77X-D3H motherboard. I have two 256-MiB SSDs and two one-terabyte mechanical drives. I have wired LAN. One of the SSDs hosts Windows 7 64-bit Pro, and the other hosts Mint 14 Cinnamon. Unfortunately, the LAN chip on the Gigabyte motherboard is an Atheros AR8161 which is not yet fully supported in Linux. I was able to obtain a tarball from http://www.linuxfoundation.org/collaborate/workgroups/networking/alx and was able to successfully manually install (the driver name is "alx") it while running Mint from a live USB. I also was able to get a debian installer package from http://security.ubuntu.com/ubuntu/pool/main/l/linux-backports-modules-3.5.0/ and got that to work in the live USB version. However, when I did the actual installation of Mint 14 onto my SSD I ran into problems. After installing Mint 14, I copied the tarball from my thumbdrive and manually installed it. Then I rebooted. Upon reboot I was prompted for my user name and password, after which I briefly got a black terminal screen again asking me to login, and then it reverted back to the GUI login screen. This happened over and over. It also happened after I reinstalled Mint 14 and used the debian package installer. After I reinstalled a third time without installing the LAN driver, I was able to successfully login.
So here's the problem: the only way I can get Mint 14 to let me login is to NOT install the Atheros LAN driver at all. But this leaves me without an internet connection, or a connection with any other computer.
Can anyone offer any suggestions?
