My (casual) understanding was that with Gnome Shell the issue was graphical corruption, but maybe there are other issues as well ?
There doesn't seem to be much community interest so we may have to give it another push ourselves. Seems like some kind of "fake mid" profile would be a good next step.
Yes, the Gnome 3 shell does have graphical Corruption on the Upper bar that causes text to become unreadable.
A "fake mid" profile could simply be adding the gpu speed control code into the open drivers. However, from this it'd be set the gpu at about 50% of it rated max speed.
Anyways, There is two major features that i can see that would be useful to have as xorg extensions. The first extension is to improve Multi-Monitor configuration hotplug support within the xserver. The only reason i state this is that this is a major feature for mobile users. I personally find myself using three main modes. Built-In display, HDMI Output only, and then Both. As for both, it'd be nice to be able to change from Display Spanning ( Big Desktop ) to Multi-Desktop Setup ( Separate Desktops ) without having to reboot in any fashion. The other extension is about Multi-GPU support improvements. After all, it'd be nice to switch graphics card configurations without having to restart the xserver. A a good example of this is to go from the Integrated Graphics (Intel, or Low end Radeon) to a dedicated GPU. This is also a major focus on Mobile users, however it probably will find some use for desktop and workstation users also.
Decent direct rendering just arrived: http://www2.ati.com/drivers/hotfix/c...x86.x86_64.zip
Check this with KWIN_DIRECT_GL=1 - almost 60 fps!
Don't worry about watermark, it's easy to fix. Put two files to /etc/ati.
