screen flickering when install fedora21
When get to the install GUI, screen begins flickering very quickly. Same issue happens when I try to install EvolveOS beta1.1.
I am using an old Compaq nc8430, lspci | grep VGA shows: 01:00.0 VGA compatible controller: Advanced Micro Devices[AMD] nee ATI M56P [Radeon Mobility X1600]
How can I solve this?
