this issue happen on ATI PARK PRO DID 68e0 machine.
when I log into linux on console mode,
and execute startx or xinit manually,
the garbage screen appears about 0.5s.

and if I add "NoAccel" "true"
or "NoDRI" "true"
it won't happen.

does someone has any suggestion about this garbage screen?

Thanks a lot

below is the garbage screen I took:
