I have a Qt application, I have added it to ~/.config/openbox/autostart.sh like this:

(sleep 5 && /home/user/UI/UI) &

When I start Openbox from terminal, the Qt application opens as a unusable gray box. If I launch xterm on Openbox and then manually start the Qt application, it works fine. What am I doing wrong?

Is this a java app? –  Caleb Jun 16 '11 at 20:21
No it's not. It's just a simple Qt app with dependencies to Qt libraries only. –  user44556 Jun 17 '11 at 1:30
Qt is a graphical toolkit that you use to create windows and widgets and stuff, but not a programming language. Any idea what language the program is written in? –  Caleb Jun 17 '11 at 7:38
C++, compiled on the same system. Even with Hello World this problem occurs. –  user44556 Jun 20 '11 at 2:59
