Well… I will survive, I had “3.4.6-1.1-desktop x86_64”(and 12.2 Live 64 CD) on the plattform “AMD A8-3850 APU with Radeon™ HD Graphics” and finally it works to install “amd-driver-installer-8.982-x86.x86_64(amd-driver-installer-12-8-x86.x86_64.zip)”.
I had huge problems to have 2xmonitors working after screensaver/sleep/hibernate with the radeonHD. Didn’t work for me.
Thanks AMD.
