Description Jan "Yenya" Kasprzak 2007-11-06 11:59:33 EST
Description of problem: My workstation has an ATI Radeon 7500 card with two monitors: 1600x1200 connected to the DVI port, and 1280x1024 on the VGA port. I do not use a MergedFB, Xinerama, or XRandR display, just plain old two separate screens (:0.0 and :0.1). This setup is no longer working on Fedora 8: Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.7.195-3.fc8.x86_64.rpm How reproducible: 100% Steps to Reproduce: 1. Install Fedora 8 2. Use the attached /etc/X11/xorg.conf 3. Run "Xorg" Actual results: Xorg fails to start with the following message: "Requested Entity already in use!" Expected results: Xorg should start with two separate screens available, as it did in F7 and FC6. Additional info: Downgrading to the xorg-x11-drv-ati-6.6.3-4.fc7.x86_64 package from Fedora 7 updates solves the problem. I do not want to use a merged screen (Xinerama, MergedFB or XRandR), because I want GNOME workspace switcher to switch virtual desktops on each monitor separately. This is apparently not possible with one big virtual screen. Also both of my monitors have different DPI (they are roughly the same height, while the first one has 1200 pixels height, and the second one has only 1024). So I want the screen resolution to be reported to the X clients correctly, based on which screen they run on. I maintain an official Fedora 8 mirror, in case you wonder where I got the F8 installation media before the release date ;-)

Created attachment 249441 [details] xorg.conf for two separate screens
Comment 2 Dave Airlie 2007-11-06 17:39:02 EST
upstream has deprecated this feature in the ATI driver. randr-1.2 is now the supported method for dual-head on the ATI driver. While it might be possible to bring back the functionality, Fedora isn't the place to annoy, upstream is.
Comment 3 Jan "Yenya" Kasprzak 2007-11-06 17:56:12 EST
OK. I will probably try to bother GNOME people instead: implementing per-monitor workspace switching could be easier (and more universal) than bringing the deprecated functionality to the radeon driver.

Speaking of upstream - where exactly is the upstream? Is there any ATI-specific mailing list on x.org?
