Graphics problems on AMD A6-6400 processor + Asus A68HM motherboard

[Manish Jain]

Hi,

I just installed a new Asus A68HM motherboard with an AMD A6-6400 
processor. The board has onboard ATI Radeon 8470 graphics adapter chip.

I installed a fresh copy of FreeBSD 10.3 amd64, with great hopes that 
everything would work out of the box. It did not. The graphics output 
under Gnome is skewed - half the text of Applications menu list  is 
missing and strange streaks appear at a few places on the screen.

To check whether there was any RAM problem, I ran a couple of passes 
under memtest86 with no errors. There are no page fault reports at 
boot-time either.

I then installed OpenSuse 42.1 leap, where the graphics output is 
normal. But I want to move back to FreeBSD - that is the only thing I like.

Can someone please help me try to get normal graphics with the new board 
and CPU ? If it is not possible under 10.3, I can wait for a fresh 
release like 11.0. But I must get things working normally under FreeBSD, 
else all of my money would have been wasted.


Thanks for any help.
