Hi All,
I am trying to port the DirectFb & sample applications on to my x86
machine and enabled framebuffer as mentioned below.
1. I have commented *intelfb, vesafb, vfb, vga16fb* from
blacklist-framebuffer.conf
2. added these modules in inramfs.conf and update initramfs
3. added the vga=0x317 to the bootargs
4. rebooted the machine after that i have found that /dev/fb0 && /dev/fb1
After above steps I have compiled the directfb and examples for x86. When I
run the df_andi i got the below error messages.
