Hello, again!
Got a new (used) thinkpad, at last. It's not a A21p any more, but I've
got the predecessor A20p. It has got the same graphic-chipset from Ati
but the display does not reach the 1600x1200 from the A21p ("only"
1400x1050) - apart from that it is pretty much the same machine. At
least the mobo is totally identical.
I've experienced the same issue, if I take a "normal" xorg.conf. The
screen is garbled like described above. This means, that my problem is
reproducible on other machines, too. Unfortunately, I can't prove, that
my "new" thinkpad's has a broken GPU, too - but it seems very unlikely
to me. Also, I can say, that this machine is not in such a bad
condition, my old thinkpad was...
Maybe I should mention, that I'm using squeeze, now.
Maybe this is related to my problem: I read on phoronix, that the coming
kernel-version 2.6.33 has some fixes with EDID - so _maybe_ this bug
will be solved, soon:
"The core DRM in this pull request is also carrying a number of EDID
fixes to help those with quirky monitors[...]"
(From http://www.phoronix.com/scan.php?page=news_item&px=Nzc4OQ)
When 2.6.33 is ready, I'll give it a try and let you know.
(I didn't know, that the kernel's also responsible for the EDID stuff -
so maybe, I filed the bugreport against the wrong package?)
Greetings
Mitsch
