I have asked on the Grass list, but maybe some one here can help. I have installed Grass via the Ubuntu repostories.

Running it gives me the initial screen where you choose your mapset, but when I click on the "Enter Grass" button , the GIS manager opening screen apears briefly and the Grass closes completely.

I know this is ratehr vague but has anyine any idea what might be happening.

Many thanks,

Graham
