I tried two ways to install fglrx driver (Debian repo, official run file).
But I have the same issue with the two ways.
I did the next steps:
- apt-get install fglrx-driver
- aticonfig --initial (I tried add only device section too => ATIProprietary - Debian Wiki )- reboot
- Lightdm not start (I must remove xorg.conf and restart lightdm to have a graphical interface)
I attach my lspci entry and my xorg log.
Thanks for your help.
