    Again.. If you can, Thx for your help
    There are three options for using dual displays with Ubuntu 8.10

    1. RANDR1.2 - single surface with 2 monitors a command similar to the following sets the output. Note that you need to ensure the virtual size is large enough to support your maximum resolutions.

      Code:
      xrandr --output DFP1 --left-of --output DFP2
      This should be what comes up out of the box.
    2. Multi-head - (some call this zaphod mode), you have two X Screens (:0.0 and :0.1), the desktops are essentially independent, with the mouse and keyboard shared with them (focus controlled by the mouse).

      You can configure this by

      Code:
      aticonfig --initial=dual-head  (use -f if needed)
    3. Xinerama - Multi-head with a unified workspace. This is effectively a hack on dual head that is more useful with multiple ASICs. For a single ASIC, RANDR1.2 or later is vastly superior.

      You can configure this by

      Code:
      aticonfig --intial=dual-head --xinerama=on

    Please note that there may be bugs, so provide feedback on the behaviours and we can go from there.

    Regards,

    Matthew

      Thank you Matthew, your fast answer is very welcome.

      I think, I have understood the 3 ways you mean. But I need some presisions :
      - How can I create a virtual size (needed for the first option)?
      - Is that possible even if fglrx is said "not randr 1.2 compliant" ??
      - Why is this command :xrandr --output DFP1 --left-of --output DFP2, not available with the graphical tool amdcccle ? (options are not available like it was on intrepid)

      Thank you again Matthew

      • Outputting to a TV via HDMI doesn't work in 9.5 either.
        Works fine in radeonhd using xrandr --output DFP1 --auto
        Not so in 9.5... crashes with

        X Error of failed request
        Major opcode of failed request: 157 (RANDR)
        Minor opcode of failed request: 29 ()
        Serial number of failed request: 27
        Current serial number in output stream: 27

        And no amount of trickery with amdccle or xrandr flags output anyting to the TV.

        • Hi,
          I've noticed that my 4650hd is always at full speed since I use catalyst 9.5. I didn't checked on 9.4, but I'm quite sure it worked with 9.3...
          First I thought it was due to composite manager, but it is not. I always have several gdm sessions opened, maybe it is linked to ?
          Have someone noticed such a problem ?

          thx

            Where can i get the patches ?
            Is there any how-to ?

              As for the how-to, no idea. But anyway, I don't recommend to run it on 2.6.29. The drivers reports "bad kernel data" all the time.

              • 9.5 on 2.6.28 = everything perfect (compiz, opengl, video), except:

                since 9.3 the "Override Application Setting" in amdcccle for "Anti-Aliasing" has no effect in Quake 3.

                any ideas how to fix this?

                distro: gentoo ~amd64
                xorg: 1.5.3-r5
                randr: 1.2.3
                randproto: 1.2.2
                libdrm: 2.4.11
                ...

                  That's the "short" patch i use for Kanotix, that required that you additionally install some extra headers. Those are not there in Ubuntu (and other) default kernel packages - therefore i patched the kernel packageing. Do not expect it to work everywhere.
