I'm not expert on Linux, so I apologize for my question in advance. I searched everywhere but I have not been able to find the way to avoid X system to start on UDOO quad. Could please someone help me? TY.
I'm not familiar with upstart, i don't know if this is the correct way but for me it worked. I solved this problem editing the file Code: /etc/init/lightdm.conf appending a row with the word Code: manual I found the solution here: http://upstart.ubuntu.com/cookbook/#manual After that, if you want to launch manually the graphic system you can use Code: start lightdm
Thank you Nicola, I will give it a try tomorow. In the meanwhile I can say that at least I discovered that it exists upstart (something completely new for a newbie like me ! Someone in other forum suggested to remove lighdm, obviously this is not a very clean solution (but it works).
