Ok,so now using an active converter (Sapphire with Eyefinity logo), but still the same problem, perhaps it could be a bug after all. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

You might also want to try the recent DP patches I posted for 2.6.40.

The fact that you can make it work with some fiddling is pure luck and is completely unsupported. You end up with one of the plls driving two monitors which only works if both monitors have the same clock and you get the ordering right. Switched HDMI for DP, so now running 2 x DVI and 1 x DP, I get exactly the same symptoms. Alex -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

It's just possible to make out shapes of icons, windows etc. that should be displayed on the screen. In troubleshooting I have discovered that if I install the closed source driver reboot, and then uninstall it and reboot again back into the open driver then the 3 monitor setup works fine with the open driver. I think the closed driver must be setting somthing up during boot that allows the open driver to work with the 3rd screen so long as I havn't removed power completely only booted with a reset. I can tell early in the boot which screen is going to have the problem by the cyan background. I have the monitors connected to the 2xDVI and 1xHDMI, the DP is unused. Not a bug. Only 2 non-DP monitors are supported since there are only two plls. If you want 3 or more monitors the rest have to be DP.
