Hello all, first post to the mailing list but a user of 6 months.
I have a working mythtv system that I recently acquired a cheap
powercolor radeon 9250 card for. The TVout is amazingly clear, using an
SVHS to SCART cable, but the overscan (or lack thereof) leaves something
to be desired.
First of all, there seems to be a bug in many of ATIs driver releases
that totally prevents the card from overscanning at all - the
fireglcontrolpanel application has no effect whatsoever on the screen
size. This applies (as far as I've seen) to all releases since 8.16 of
their xorg driver. Wether it also applies to the regular XFree86 package
Secondly, even in those driver releases where the fireglcontrolpanel can
modify the image, the Xserver is ignoring the settings in the config
when it loads. Only after I fire up the control panel application does
the screen adjust to the preset overscan values - which clearly is not
how things ought to work
Since I refuse to believe that this is how it's supposed to be, I'm
hoping for some feedback from other ATI users on the list who
(hopefully) have a working setup.
My own system runs on the following config;
Framebuffer in kernel, using standard vga driver
kernelversjon 2.6.12-6 (gentoo-sources)
Motherboard: EPoX 8HMMI-A (VIA K8M800 chipset, mATX formfactor)
ATI drivers tested: 8.8.25, 8.14.13, 8.16.20, 8.18.8 & 8.20.8
It would be very helful if you could please post your own config if you
are able to adjust overscan and have it stick.
