Re: [Dri-users] TVout in mach64-0-0-7-branch?

[Mike M. <che...@ya...>]

I have patch the 0-0-7 branch and after fixing some HUNKS it compield and
I was able to enable the TVout option.  However xrandr didn't change to
the TV, nor did a restart of X.  I use atitvout to change to the TV, this
worked.  When I went to use Xvideo it had problems and I coulden't get a
good framebuffer(The screen was a vary clear mess of cliprects) so I
rebooted.

I will submit a patch the applyes cleanly to the devel list.  I only had
to move a fue things around in the existing patch.
