Salve hugH, Karl, mi, Frank, Ionel! Thank you very much for your support. I tried 2 hours today to make it run but faild. So I will start with reading and learning the basics of X-server, windowmanager and desktop manager. I will postpone this after my exam in two weeks, but I promise to write here how to install and use an other windowmanager like blackbox. ;) Thankfull, rob
