first of all i will say sry for my bad english .
I run Linux Mint 15 Cinamon on my Acer Aspire v5-551g, it has an APU A6-4455 amd inside.
My problem is, when I close my Laptop and open it again its very slow and when I press the buttons for the shortcut 'Toggle Expo', Expo opened but the Background of the workspace is black.
I tried o AMD Linux Catalyst driver and could fix some bugs, like the laptop used much Battery, and wake the laptop up again didn't go.
The problem was the 'xserver-xorg-video-ati' driver. I switched to the 'fglrx-updates' driver '2:9.012ubuntu1' .
I hope anybody can help me
