Hello Peter, Thank you for your response. After I tried running with sudo, the keyboard and mouse work, now! Also, I created /etc/udev/rules.d/99-input.rules with following content:
KERNEL=="event*", NAME="input/%k", MODE="664", GROUP="input" Then, I rebooted BBB and all the events have read permissions. The qt example programs works. By the way, I noticed another problem. When the Qt programs are running, the terminal's cursor is still flashing. Sometimes the whole terminal screen will pop-up for a very short time. So the whole screen is flashing. I think this is because the terminal is trying to refresh the screen. How can I stop terminal from refreshing the screen? Thanks! (Should I start this problem in another thread?)
