While booting the installation program (via USB), the screen goes black, it looks just like the screen has been switched off.The laptop is a Lenovo Ideapad z475 and, as per the Beginners' Guide, I've tried to use i915.modeset=0 and video=SVIDEO-1:d, still the same black screen however.The graphics card is AMD(ATI) AMD Radeon HD 6470M & HD 6520GThe installation media is archlinux-2011.08.19-netinstall-x86_64/archlinux-2011.08.19-core-x86_64
Got a black screen while booting archlinux installation program
arch linux;video;system installation
If Kernel Mode Setting (KMS) is inhibiting your graphics card from working properly, you can disable it by appending radeon.modeset=0 to the grub line.If that fails, try a simple nomodeset.For more information about running an ATI card under Arch, see the ATI page on the Arch wiki.
