Question

i’m porting android to an overo gumstix. thus it seems the the omapfb driver has some problems on that platform. it doesn’t matter at all, because i want to use udlfb (a driver for usb displays) anyway.

till today, i wasn’t able to figure out how i can define udlfb as default framebuffer.
tried make menuconfig and select udlfb there, but no changes when booting the fresh compiled kernel. omapfb still wants to come up.

• so my final question: how do i define
  the default framebuffer driver for an
  android kernel?

thank you for any suggestions to this 🙂

Answer 1

You can try to disable omapfb in your kernel. In make menuconfig:

-> Device Drivers
 -> Graphics support
  -> OMAP2/3 Display Subsystem support (EXPERIMENTAL)

Disable the last option.

Also, be sure that udlfb is enabled by default (ie not in module).
