I've got Lenovo G500 intel i5 with switchable graphics (Intel and AMD Radeon HD 8579M). When I try to install Linux Mint Petra Cinnamon, when switchable graphics are on by the bios, live CD can't start Xserver and crashes (blue screen. "want to see log files?" etc.).

I have tried to install Ubuntu (Saucy Salamander) too and got only black screen (can't get to command line interface).

I have managed to install Mint Cinnamon with turning off switchable graphics. After that I tried to install a working desktop while SG on.

Ubuntu crashed, KDE Plasma works only in fallback mode.

While switchable graphics are turned on, only Xubuntu works.

On Xubuntu I had tried to install fglrx via distribution packages, installers and apt-get, but my every attempt has been failed.

There is no buildpkg for AMD driver Ubuntu/Saucy


nor in


I tried to add repository, but it doesn't seem to work:

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install fglrx-installer

E: could not locate the package

Right now I uninstalled every bit of fglrx and turned off SG. I'm now using Cinnamon.
