I installed Titanium on my Ubuntu 10.04, all went ok.
But now when I try to start the software nothing happens, no windows opens and no error message appear.
Anybody can help me?
Are you saying that Titanium Developer won't run at all?
If so, ensure that you have Sun's JDK 6 revision 10 or later installed (not JDK 7, and not Open JDK).
Ensure that your JAVA_HOME environment variable is configured correctly, to the above JDK.
If you are using TiDev via a proxy, ensure that you follow this post
I've have the same problem and resolved with this post http://journal.dalopez.com/post/1233148348/titanium-desktop-on-ubuntu, I use Ubuntu UE (10.10) and working to the 100%.
