there is a bug or problem with kdm and radeon together,

it was discussed here some time ago, but I couldn't find it anymore.

I had such a problem and solved it by installing GDM and using it instead of KDM.
Dear Violinist (what a great instrument !),
You are correct. It's kdm and I have an ATI Radeon mobility card.

Will switch to GDM.

Thank you.
