Hi, thanks to all. Brian is right with his opinion that I'm not subscribed to the list. I sent a 'subscribe' to <mailto: debian-user-requ...@lists.debian.org> but didn't get an answer (or at least I didn't find it).
How do I switch drivers under Debian, especiallay from the "AMD FGLRX driver for Radeon adapters" to the "free radeon driver, which is the default in jessie"?
Kind regards, Hans PS: Please send any mails regarding this with a 'CC' to me.
