conflicts wit nvidia-glx

Thanks for reporting this bug. Can you please summarize the issues and steps to reproduce when both drivers are installed? It was not clear from the referenced bug what problems exist. Many people like to have the binary and open drivers installed at the same time, so we'd need to understand the specific issues that are causing conflicts for you.

Sorry, i thought it was trivial.

The problem is when you install xorg-driver-fglrx beside xserver-xorg-video-ati or nvidia-glx beside xserver-xorg-video-ati than 3D (DRI) is gone.
Note: xorg.conf is untouched and use always ati

Applications like google-earth don't work anymore.

The problem is that fglrx and nvidia binary X drivers need their own GL libraries. These libraries only work if you have the matching binary X driver AND a matching kernel module.. If you ever had a machine that needed to use two differing graphic card models (e.g. an ATI and an NVIDIA or an ATI and a Matrox) and one need to use binary drivers, you would never be able to have accelerated 3D on both cards at once since only one GL library can be used at a given time. Another issue arises if you leave a binary only set of GL libraries installed and then switch to a "regular" xorg driver. Setting conflicts probably isn't a great solution as people could find the old ATI driver pulled up when switching to fglrx and thus struggle to switch back...

fglrx no longer needs it's own libGL.

Actually, my last comment was bogus.

Adding a conflict is not feasible.
