Thanks Bridgman if you can suggest me some workarounds. Here are the poor and messy part of radeon oss on my e-350 apu (hp dm1z, kubuntu 12.10).

Messy: Occasionally I can't connect it with my HDMI. Even when I change/share screens from "1366x768" (my laptop res.) it's not seamless, whereas win7/catalyst manages quite well, adapts as per the display in question.
Is it just me? Or others are having such problems?
HD video performance is known - the open source drivers do not have GPU-based video decoding, so this is being done on the CPU, which likely isn't up to the task.
One feature I've never seen mentioned anywhere is support for 3D displays. Nothern Islands cards are supposed to support them on Windows over HDMI, but I've never seen any report of that working or not working on Linux, neither with fglrx nor with r600g. Am I missing something?
When you're sitting at a computer all day, you get used to seeing progress bars. Maybe instead of WIP, we can add those circular loading animations that never end.

If you want more detailed progress bars..
I give it a few weeks before we also get:

Do you hosnestly expect a "for profit" company to help out its competitors? Intel's drivers strategy seems spot on for me. I would probably do the same if I were in their position. The code is already out there, if you want to reimplement it on gallium, go on. radeon and noveau already benefit greatly from their work, there is no reason for intel to help out even more.

To me, Valve seems to be the one closest to actually acomplishing that. They are also the ones who will most benefit from a top notch linux graphics stack, since it will mean more sales on the steambox. If they feel that porting intel's driver to gallium would benefit them, they would be free to do that.
In my mind, there would certainly be benefits for valve if the 3 drivers were all oss and feature complete, since they could have more control over the platform their clients develop for. But they would have to consider the time and cost involved, which we can only estimate...
In a nutshell, i believe intel is more forward looking, not the great linux messiah. AMD almost ignores linux, and I suppose we can agree that such position will bite them in the ass in the sometime in the future.
* Hybrid Graphics - lots of work on this over the last year, mostly by airlied
I observe that things had been working less and less
smoothly as the kernel version had been progressing from 3.4 to 3.7. The version 3.8.rc3 now fails to switch to
ati card and start Xorg
I have problem to use ati card on my muxless hybrid graphics laptop.
This is hp envy-1210nr laptop with ATI/Intel cards
fglrx is unusable for my laptop SHAME to AMD and HP (http://ati.cchtml.com/show_bug.cgi?id=276)!
I used to use vga_switcheroo to switch off ati card and to switch it on when I need to suspend/hibernate or to use the
display and hdmi ports for presentation. Note that for 3.4 and 3.5 versions of kernel
there was a nice patch that allowed the comfortable use of the vga_switcheroo
Unfortunately kernel hackers rejected it. So in the kernel version 3.6 I had to start the vga_switcheroo related scripts manually.
It was not as comfortable as earlier, however it did work from the odinary user. For the kernel 3.7 the situation was changed,
so I have to use sudo everytime to suspend/hibernate. Finally, 3.8.rc3 has possibility to switch on/off the power for the AMD card but
no possibility to start Xorg on it (https://bugs.mageia.org/show_bug.cgi?id=8718).
I believe AMD invests more in Linux relative to the size of the company than Intel does.

What does this mean? Comes up in a mode you don't like? dualhead vs. clone? something else? The driver just generates an event when a monitor is plugged or unplugged. It's up to your desktop environment to decide what to do with that event.
