First time I started the client (running Ubuntu) I got a question about if I wanted to run with hardware accelleration or software accelleration.

I tried the "hardware" option, and the graphic flickering very much.

So, I wanted to try the other option, but I never get that question again.

Even if I delete the ~/.minecraft and the dir with the program, unpack it again, it still remember my options (about accelleration my login name, my password).

I have searched in /tmp, in ~, in /etc, but I cannot found the place it is stored.

Please help me.
