Hi Everyone,
Thanks to all for participating in this subject. The reason I asked these question is the following:
1) Shutdown by software. -> When I run ubuntu (with hmdi) I've got the common problem like everyone else. When running Firefox, the screen is flashing black. Other browsers do the same. When I tested leaftpad and other applications some will not start, or crash, or hang on desktop screen. This forced me to unplug the unit. Next time I ended up with desktop flashing a black screen. I assumed that ubuntu got corrupted. I think that to prevent this is to do a proper shut down by software before unplugging the power. It does not have to be hardware entirely but just microSD card (for sure) and maybe some other components. On next try I will try to burn the Ubuntu again and try to repeat that and not to do to many things at the same time.
I used separate power for my fan. I cannibalized fan from old PC junk a 12V fan and I used adjustable voltage power adapter for it but both parallella and fan are coming from same cable extension so I am turning both power cables off and on simultaneously.
2) Headless connection - >is it through second usb connector or through 3 pins or ethernet?
3) Why ubuntu linaro -> was it tested before on parallella and it worked before?
