Comment 21 for bug 289177

The same problem occurs with Ubuntu 8.10 RC. So, judging by that and the contents of the X logs, it looks like the root of the problem is that activating the HDMI (DVI) output on the Radeon HD 3200 is different than on the other cards, and the radeon driver thinks it knows how to activate it, but actually does not. I find that very interesting, since it is precisely this sort of thing that AtomBIOS was supposed to prevent. For whatever reason, the radeonhd driver knows how to activate the output, so there may be some simple change that will fix the radeon driver. I'll take a look at the sources that Ubuntu is using and try to see if a solution jumps out at me. I'm not a driver developer, so no promises.
