I followed instructions in the announcement of the Raring Hardware Enablement Stack to update my installation with
Code:
sudo apt-get install linux-generic-lts-raring xserver-xorg-lts-raring
When I try to start the system now it shows briefly some dots and the coloured word "Ubuntu". Then the screen turns black with a blinking cursor in the upper left and the machine stops reacting to anything except the off-switch. The older kernels GRUB offers can't be booted either.
During installation of the update I got an error, saying "fglrx" couldn't be installed. So, is "radeon" dead, too? How to proceed from here?
