 |

Has anybody gotten the open source radeon drivers to create two displays (ex :0.0 and :0.1) with a single card? I tried | Quote: | Section "Device"
Identifier "ATI Open Source"
VendorName "ATI Technologies Inc"
Driver "radeon"
Screen 1 Option "MonitorLayout" "LVDS, CRT"
EndSection

EndSubSection

only to get the vga to display something. It works fine with the proprietary drivers. Then I tried the MergedFB option only to get a REALLY large desktop with an LCD monitor that scrolled. I like having two different displays because I can have two wallpapers. Although the only downfall is that I can't drag windows from one display to the other. But it beats having just one giant desktop and having a monitor that can only scroll.
And playing StarCraft on the open source ati drivers is much better than the proprietary.
Any ideas?

| I don't think that I've ever gotten two separate displays (:0.0 & :0.1) before with it. I have, however, had basically two workspaces, each with its own background, using KDE, in a similar setup (open radeon drivers, MergedFB). |

Each with a different resolution without having to force one monitor to have a virtual resolution?

I do believe that was the case.
I think it was accomplished with something similar to the following: | Code: | | Option "MetaModes" "1024x768-1280x1024 1024x768-1024x768" |

Well, the following configuration does a dual head, but Xorg.0.log says "disabling direct rendering, not yet supported by this driver" or something like that. So I guess there is my answer. According to all of the configurations I read MergedFB creates a virtual resolution for the smaller monitor (which is what it did for me). So for the moment it seems I just have to use the fglrx module for regular things and switch to radeon (the open source driver) for when I need to play games like StarCraft. | Quote: | Section "Device"

Does direct rendering work when running on a single display? What is your video card model? |

Works fine in single head, the direct rendering that is. I've got a | Quote: | | 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] (prog-if 00 [VGA]) |
. The manufacturer actually said it was a 9700 but I'm assuming it's the same chipset anyway.
