Comment 29 for bug 196617

Good morning,

I had the same problem with hardy on my PC.
I did not have the proble with old Ubuntu releases.
I have changed the config:
Old xorg.conf:

Section "Device"
        Identifier "radeondvi"
        Driver "fglrx"
        Option "DesktopSetup" "horizontal"
        Option "OverlayOnCRTC2" "1"
        BusID "PCI:1:0:0"
EndSection

Section "Device"
        Identifier "radeonvga"
        Driver "fglrx"
        BusID "PCI:1:0:0"
EndSection

New xorg .conf
Section "Device"
        Identifier "radeondvi"
        Driver "fglrx"
        Option "DesktopSetup" "horizontal"
        Option "OverlayOnCRTC2" "1"
        BusID "PCI:1:0:0"
EndSection

Section "Device"
        Identifier "radeonvga"
        Driver "fglrx"
        BusID "PCI:1:0:1"
EndSection

The problem has disappeared when I set the two different PCI ids.
Unfortunately I used to have two different desktops (one per screen).
Now I have a single desktop with both screens.

I have to rtfm to reconfigure my two desktops in my xorg.conf.

See you.
