Jessie with ATI Radeon HD 4250 boots black screen after installing drivers...

[Gábor Hársfalvi <hgabi84@gmail.com>]

Hello,

I have a big problem - I use the official tutorial - https://wiki.debian.org/ATIProprietary#Debian_8_.22Jessie.22 - but when I reboot it always give me a black screen. :(

Why? And why gives me "aticonfig --initial" "No supported adapters detected"?

Thanks
