I'm new to the whole linux world. I had Windows7, so in order to not to lose it I made a new partition for Ubuntu 12.04.
After the installation everything was good except a huge problem, my lapto has an Intel HD graphics card AND an AMD Radeon HD 6470M but to my surprise I saw the system used the Intel graphics card whenever I logged into Ubuntu. I searched over the Internet but couldn't get anything.
And now comes The monumental problem, After upgrading from 12.04 to 12.10 when I rebooted and selected Ubuntu from Grub mneu, the whole booting procedure stacks every time at the purple screen and never reaches the login screen I don't know what to do anymore I feel kinda desperate.
Unfortunately I cant provide any more info. because I call myself newbie at the Linux environment. If this whole thing rings any bell , is there any way we can fix this?
