Description Fabrice Bellet 2004-09-14 13:56:40 UTC 
I have an odd behaviour, with my Radeon 8500, using xorg CVS, with MergedFB
enabled. Only when the option "EnablePageFlip" is activated, the second head
becomes a clone of the first head, immediately when I start a 3D app, for
example glxgears. No error message in the logs. The relevant part of my config
file is :

Section "Device"
        Option      "AGPMode" "4"
        Option      "AgpFastWrite" "off"
        Option      "EnableDepthMoves" "on"
        Option      "EnablePageFlip" "off"
        Option      "BackingStore" "on"
        Option      "RenderAccel" "on"
                                                                                
        Option      "MergedFB" "true"
        Option      "CRT2Position" "RightOf"
        Option      "MetaModes" "1280x1024-1280x1024"
        #Option      "MetaModes" "1600x1200@60-1600x1200@60"
        Option      "MonitorLayout" "CRT, CRT"
        Option      "CRT2HSync" "27-110"
        Option      "CRT2VRefresh" "50-160"
                                                                                
        Identifier  "Card0"
        Driver      "radeon"
        VendorName  "ATI Technologies Inc"
        BoardName   "Radeon R200 QL [Radeon 8500 LE]"
        BusID       "PCI:1:0:0"

Mergebfb and EnablePageFlip used to work together with the DRI, before it got
merged in xorg.

I've got a fix for this pending.  fixing the situation with crtc1 at offset 0 is
pretty easy.  the situation with crtc2 at a lower offset than crtc1 will require
some versioning to maintain compatibility between the drm and ddx.

Roland fixed this in cvs.  pageflip now works in all configs with mergedfb
