I have a problem with booting Kubuntu 13.10 on a lenovo G510 notebook with this specs:
-CPU: Intel core i5 4200M
-Graphic card: Intel Graphics HD 4600 + AMD Radeon HD 8570m
-S.O.: Windows 8.1/Kubuntu 13.10
When I try to boot Kubuntu with the Radeon enabled, it results in a black screen, instead if I disable it from the BIOS and use only UMA Graphics it works perfectly. So the problem is the Radeon, but I can't keep it turned off all the time, it'd be a waste! Maybe it's because I haven't installed the drivers for the Radeon, but I can't install them while the radeon is disabled.
How can I fix this?
