This may be because the primary device is the integrated Intel GPU, not the
Radeon one. Possible solutions might be removing the Section "Device" for the
radeon driver (letting it be auto-loaded via the ati driver) or adding a BusID
stanza to it.

Added BusID in Device section for radeon gpu but again startx fails with
following message : "Unable to find connected outputs - setting 1024x768
initial framebuffer" Its a Dell Inspiron Laptop.

Then it sounds like your laptop is muxless, i.e. the Radeon GPU physically
isn't connected to any display outputs. I'm afraid this won't be supported for
a long time, as it requires a lot of infrastructural work to happen first. In
the meantime, you'll have to use the integrated GPU with the intel drivers.

"In SBIOS the switchable Graphics is set to Muxed instead of Muxless. The
message, "Unable to find connected outputs - setting 1024x768
initial framebuffer" appears as warning and startx fails with segmentation
fault."
