Are you connected over the serial port? If so, you need to set the DISPLAY variable properly before running the application: 

export DISPLAY=:0.0

How are you connected to the board? Do you have a DisplayPort monitor connected?

You can use a USB network adapter. 

Or you can follow the instructions here to setup the wireless network from the command line.  I was successful with the WPA instructions:

https://www.linux.com/learn/how-configure-wireless-any-linux-desktop

Here is what it boiled down to for my situation:

1st time only:
wpa_passphrase <SSID> <PASSWORD>
copy the generated text into a new file called /etc/wpa_supplicant.conf

Subsequent boots:
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
dhclient wlan0
OR for static IP
ifconfig wlan0 <ipaddress> netmask 255.255.255.0

I would try a couple of different monitors and cables.  The display should come up at boot automatically.

不知道你是不是中国人哈
是这样的,深鉴的镜像在Ultara96板子上并不能通过DVP或者那个HDMI等方式输出,它的软件设置是连接上网络,以一种类似于VNC的方式进行输出。先要通过SSH连接上板子,我亲测MobaXterm这个软件可以使用,Putty不可用。然后在执行软件的时候,就会在主机上重新弹出一个对话框,显示对应的图片。板子上没有以太网接口,我使用了一个USB转以太网HUB,USB接板子,以太网端接主机。如果你不是中国人,自己翻译吧。。。。。
