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
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.
