Hello Mr Ben

i faced same problem as yours, when i compile a simple image show program like :

while(( (cvWaitKey(10)&0xff) != 27 ))

{
cvShowImage(“img”,img);
};

i saw that the window has no border , window stays behind the terminal, no ESC works to quit and window has no border

then i started to do your instructions you suggested

  1. Install lxdm

opkg install lxdm

  1. Disable gdm

systemctl disable gdm.service

  1. Enable lxdm

systemctl enable lxdm

  1. install xcfe

opkg install packagegroup-xfce-base

.
.
.

after that BBB doesnt enter to angstrom

i really need your help in that subject

your sincerely

Baran…
