Under the System tab of the GUI, you can select different boot modes for JeVois-Pro:
Once you are in either console or graphical mode, issue these commands in a terminal to switch:
sudo systemctl set-default jevoispro.target # to boot to JeVois software sudo systemctl set-default multi-user.target # to boot to Ubuntu console sudo systemctl set-default graphical.target # to boot to Ubuntu graphical
Then
sudo shutdown -h now
Unplug power and plug it back in.
User jevois has password jevois and is capable of sudo (using that password).
User root has password jevois
JeVois-Pro software runs as root by default.
If you have switched to Console boot, after you login (either as jevois/jevois or root/jevois), you can start the JeVois software from the command-line:
sudo jevoispro.sh
Note that the GPU drivers provided by ARM for our chip (Amlogic A311D) work in full-screen framebuffer mode only. So they work perfectly when booting in JeVois-Pro mode or Console mode. But if you run sudo jevoispro.sh
from a terminal in X-windows, you will get conflicts between two graphical interfaces (X-windows and the JeVois GUI). You will see 2 mouse pointers, some X windows will refresh on top of the JeVois display, etc. Thus, if you want to run jevoispro.sh manually, do it from the console mode.
When you are in console mode, you can start X-windows by typing:
startx
and when you logout from X, you will get back to your console.
This is very useful for development. You would do as follows:
sudo jevoispro.sh
allowquit
parameter of the Graphical User Interface (you need to turn on showing system parameters first). Or you could also start with sudo jevoispro.sh --gui --allowquit
which will allow you to exit JeVois software when you press the ESC key.startx
and logout from it when you are done.sudo jevoispro.sh
again, etc.
