There are some video cards that have trouble booting into the graphical installation program. If the installation program does not run using its default settings, it tries to run in a lower resolution mode. If that still fails, the installation program attempts to run in text mode.

One possible solution is to try using the resolution= boot option. This option may be most helpful for laptop users. Another solution to try is the driver= option to specify the driver that should be loaded for your video card. If this works, it should be reported as a bug as the installer has failed to autodetect your videocard. Refer to Chapter 8, Additional Boot Options for Intel and AMD Systems for more information on boot options.
