Erro Netbeans no Ubuntu! [resolvido]

[Luxu]

Galera uso o NetBeans tanto no Linux(Ubuntu) como no Windows, mas no linux esta fechando simplismente do nada...executei ele pelo terminal e olha o erro que retornou:

The program '<unknown>' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 2381859 error_code 8 request_code 139 minor_code 4)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)


Reinstalei o Ubuntu...

Alguem tem ideia do que possa ser?
