  • problems with FGLRX 9.4 on ubuntu 9.04 HD4550

    I have an ATI HD4550 with a DVI, VGA and HDMI output. The documentation says HDMI + DVI works together, so thats what i'm trying to do with my two dell 24" monitors. (an HDMI to DVI apdater is used)

    Ok, i got the fglrx driver 9.4 from amd's site and did an aticonfig --initial=dual-head.

    That gives me a config where there are two different screens. I try the big desktop which tells me that RandR 1.2 is enabled so it wont work.

    AMDCCCLE cant seem to do anything, and twinview is greyed out.

    brendan@brendan-pc:~$ fglrxinfo
    display: :0.0 screen: 0
    OpenGL vendor string: ATI Technologies Inc.
    OpenGL renderer string: ATI Radeon HD 4550
    OpenGL version string: 2.1.8591

    my current slightly modified Xorg conf, which gives me mirrored screens, i am completely lost.

    Code:
    Section "Monitor"
            Identifier   "aticonfig-Monitor[0]-0"
            Option      "VendorName" "ATI Proprietary Driver"
            Option      "ModelName" "Generic Autodetecting Monitor"
            Option      "DPMS" "true"
    EndSection
    
    Section "Monitor"
            Identifier   "aticonfig-Monitor[0]-1"
            Option      "VendorName" "ATI Proprietary Driver"
            Option      "ModelName" "Generic Autodetecting Monitor"
            Option      "DPMS" "true"
    EndSection
    
    Section "Screen"
            Identifier "aticonfig-Screen[0]-0"
            Device     "aticonfig-Device[0]-0"
            Monitor    "aticonfig-Monitor[0]-0"
            DefaultDepth     24
            SubSection "Display"
                    Virtual 3840 1200
            EndSubSection
    EndSection
    
    Section "Screen"
            Identifier "aticonfig-Screen[0]-1"
            Device     "aticonfig-Device[0]-1"
            Monitor    "aticonfig-Monitor[0]-1"
            DefaultDepth     24
                    Virtual 3840 1200
            EndSubSection
    EndSection
    
    Section "Module"
            Load    "glx"
    EndSection
    
    Section "ServerLayout"
            Identifier     "Custom Layout by brendan"
            Screen      0  "aticonfig-Screen[0]-0" 0 0
            Option  "Dualhead" "true"
    EndSection
    
    Section "Device"
            Identifier  "aticonfig-Device[0]-0"
            Driver      "fglrx"
            BusID       "PCI:5:0:0"
    EndSection
    
    Section "Device"
            Identifier  "aticonfig-Device[0]-1"
            Driver      "fglrx"
            BusID       "PCI:5:0:0"
    EndSection
    Please can anyone help me?

    I've tried with VGA and DVI and the results are the same, THe problem seems to be that both monitors are seen as the same, so when i manage to tell them not to clone each other they do anyways cause they are the same monitors.

    The displays applet in gnome sees a green and blue monitor, but when i tell it to identify screens it shows a blue thing on both monitors.

    Thanks.

    Hallo,

    I've got a similar problem here. Two Monitors (Iiyama Prolite B2403WS) connected via DVI-HDMI-adapter to a Radeon HD 3470. The dual-head config does not work since I installed catalyst 9.4.
    Even Xinerama is greyed out (worked once till the next reboot).
    I switched back to catalyst 9.3 which will a least work in that way that dual-head works almost ok.
    The only problem: If I switch off the monitors and switch them on again. I always have the clone mode active. I have to go to ccc and correct that. But that is better than having no dual-head at all.

    If there is a solution please tell me!

    Thanks!
