Bug#484015: xserver-xorg-video-ati: [r128][powerpc] output is limited to 800x600 even with 1024x768 display

[Rogério Brito]

Hi there.

I finally made X work with full 1024x768 resolution on this iBook.
(hooray!). I'm sending a copy of this to -powerpc for reference and
future googlers.

First I downgraded the whole Xorg and its components to the stable
version (etch?). Then, I was conservative and used dpkg-reconfigure to
configure the monitor. It worked *fine*.

On the other hand, using a configuration file (xorg.conf) from sid on
the etch branch gave me the same results as if I were using sid.

But keeping the etch-generated file with sid xorg.conf worked fine.

I think (I'm investigating this right now) that the issue here is that
the modern Xorg configuration tools don't write the monitor frequencies
(if I ask X to configure itself with "X -configure"), while they seem
crucial on this machine for it to work.

(Just tested it)

Yep! That's it: the lines with the monitor frequencies are *needed* for
X to work with the correct resolution.

Even though I made this work, I think that this bug is quite not done
yet, but I can lower its severity to normal.

Nice. I can bisect it now to see the culprit changeset.


Thanks, Rogério Brito.
