package fglrx (not installed) failed to install/upgrade: Unterprozess installiertes post-removal-Skript gab den Fehlerwert 1 zurück

[Max]

I installed it and after the next reboot Ubuntu started in Low-graphics mode. Then I was trying to fix this with the help of a forum and I couldn't install xserver-xorg-video-ati. Finally, I installed fglrx-updates and this is actually working.
