updated radeon driver x1600 loses signal to monitor

[Wise Ferret]

Ubuntu 8.10 on lg-s1 laptop, x1600.

I use the radeon driver. The last version working for me is:
1:6.9.0+git20081003.f9826a56-0ubuntu2,
on the ubuntu main repos.
When trying to upgrade to any later version (I tried several) I get a weird issue: the system goes up normally, I get sound and can login - but the screen is completely black. I have no signal, and the system is unaware of it.

Reading some readme files, it looks like the problem is a change done for the sake of rv530 chipsets on mac laptops. Apparently it messes up my none-mac laptop using the same chipset. It could be the explanation for the troubles of this guy:

Any idea what I can do, or whom I should contact?

Either :

- send an email to the xorg mailing list
- file a bug against radeon on the x.org bugzilla system
- ask for help on the #radeon IRC channel

The x.org home page has links with more info on all of the above ;

http://www.x.org

You may also get an answer here, either from a user who has seen the same problem or from one of the devs.

Thanks. I have reported the bug: https://bugs.freedesktop.org/show_bug.cgi?id=18990

I am also using a MacBook Pro (v1) with a RV530 and it's working perfectly with the xserver-xorg-video-radeon package from https://edge.launchpad.net/~tormodvolden/+archive .
Can you try installing it and report back?

I have tried installing from this very ppa repository yesterday and the blank screen is still there.

As I noted in the bug report, the last working verking version is:
1:6.9.0+git20081003.f9826a56-0ubuntu2
and the first non-working version is
1:6.9.0+git20081003.f9826a56-0ubuntu2_1.

The changelog between the two reads:

xserver-xorg-video-ati (1:6.9.0+git20081003.f9826a56-0ubuntu2.1)
intrepid-proposed; urgency=low
Add 103_dithering_rework.patch: Complete, correct fix for dithering
issues we'd initially worked around in patches 101 and 102. Those
patches also appear to have introduced regressions on certain hardware,
which this rework addresses more elegantly. This patch essentially
includes all of upstream's work up to commit 435cf7da, except that it
drops commit 0975e007 (rename radeon_memory to radeon_legacy_memory)
which is unrelated to the dithering problem.(Closes LP: #274234, #284346)
