Breezy and Ati Radeon 9700 Pro dual head


Hello!

I have Ubuntu 5.10 Breezy distro, Ati Radeon 9700 Pro card and two CRT displays.

I want to use the both screens, and I have done this so far.

1) First was basic installation what came with the distro.
Driver was Ati, and I modified xorg.conf, so that it uses both screens.
Problems:
- It seems I have two different "computers". My left screen was using finish language pack and right screen was using English.
- Both screens had own separate panels (i.e. both did had clock on right bottom)
- OpenGL 3D hardware accelerator did not work.
- I could not put window between the screen. (i.e. left screen have part of it, and the right screen has the rest)

2) Then I installed ATI proprietary drivers from Ati.com.
Everything looked real nice. Only left screen had panel, I could use windows between the screens, both screens did have own separate screen-savers, video played nicely. If I maximized window, it only expanded to the size of screen in use. Except one
problem:
- OpenGL 3D hardware accelerator did not work
The fglrx driver was from mesa3D I think.

3) My last test was uninstall the the current (the one with came ATI proprietary driver) fglrx driver and install xorg-driver-fglrx package.
Now the OpenGL 3D hardware accelerator works fine, and Tux Racer, glxgears and fgl_glxgears works fine. I did not change anything from /etc/X11/xorg.conf (what was generated by ATI proprietary driver installer)
Now the problems are:
- Now it seems there is absolutely only one desktop what is wide as both screens. (i.e. panels go all the way from the left screen to the right screen, programs starts at the middle of both screens, and so on)
- Screen saver runs only in the left screen
- There is some odd video problem, videos are some how stretched horizontally

What I want, is to have usability like with the ATI propriorietary drivers, but with the OpenGL 3D hardware accelerator.

Question:
Is it possible to have all the good sides but none of the bad sides in same time?

Is it easier to make the ATI proprietary driver work with the hardware 3D accelerator or can I configurate xorg.conf to have same usability options as ATI prorietary driver?

So should I proceed from stage 2 or stage 3?
