Well after trying for two days to get rid of the system error in Ubuntu 14 with the RTAI kernel and Linuxcnc installed, I gave up. The error may not have affected LinuxCNC, but there was no way of telling for sure so why take a chance when this computer is going in a full size vertical mill. I tried loading Debian 8 x64 with the ISO installation of LinuxCNC but could not get the drivers to load for my Radeon display driver. Here again I did get the LinuxCNC loaded and it would drive my little Sherline 4 axis mill, but every time I started the computer I got an error message about missing Radeon drivers. Again it may not have been an issue with LinuxCNC, but why take a chance and it was annoying. In the end I switched over to Mint LMDE2 x64 with the KDE interface and everything loaded right up the first time. I have internet, my full resolution display, my touchscreen, and no error messages during startup. I am not a big fan of the Mint GUI, but once I get this computer integrated into my retrofitted mill I am going to set the system up so that on boot up it goes directly into LinuxCNC. If I want to surface the internet or write a letter, I will use my regular desktop computer. I just ordered the Mesa 7i77 - 6i25 setup to interface this computer with the existing servos, relays, and sensors on my Tree 325, so as soon as the board arrives I will start the retrofit.
