    Don't know if sudo exists on the current RH distros, so run as root if not. Again, X should be stopped before you run these.
    Code:
    # aticonfig --get-pcs-key="DDX,EnableRandR12"
    Error: Key DDX,EnableRandR12 not found in PCS database
    Nope that was not it... maybe named as something else?

      Maybe replace Enable with Disable ? You could also take a look in amdpcsdb for any mention of RandR.

      It's possible that the non-RandR code paths have been removed, not sure. Will try to find out but it won't be until mid next week at the earliest.

        No mention of randr at all in amdpcsdb. Tried several grep's (enable, disable, randr) etc.. Could not see anything important with aticonfig --help either

        Would be really grateful if you could check this. Changing OS just to get rotation support is not on my wishlist. As RHEL 5 is a supported OS I think this should work and if Nvidia can do it so can ATI . As fglrx is used by the workstation market I think this feature is important as a lot of workstations use larger screens and with that the pivot function is often included.

        Ill help as much as I can if you need more info about my system. You could also point the dev's to this bug if they take their time to look into this issue : http://ati.cchtml.com/show_bug.cgi?id=1841

        Thank you for your time and have a great weekend !

          Does NVidia support RandR ?

            xrandr -o X

            X from 0 to 3

            works definitely with nvidia.

              I have a Nvidia Quadro card here. Tested in the same box as this ATI HD5770. The Quadro card does rotation just fine under CentOS 5.5. So I don't think ATI should miss out on this feature which is becoming increasingly important as screensizes increase and which is now missing/not working on a supported distro.

              Regards

                nvidia does not fully support randr 1.2. For example, you can not use xrandr (or even twinview) to rotate just one monitor. In that case, you have to use multiple screens and combined them with xinerama.

                      Bumping this to get Bridgmans attention Did you talk to the devs about being able to use rotation/pivot on RHEL 5.5 / CentOS 5.5 ??

                        Tried rotation on Catalyst 10.7 with a HD5770.

                        Rotation in CCC is still missing in RHEL 5.5

                        # xrandr -o left
                        Result in Big Desktop mode: Screens goes to standby. PC hang.

                        Result in single display mode: Rotates screen but not menues and leaves a black border to the right.

                        @bridgman can you please give this info to the devs and check if this is a known problem on RHEL 5.5 ?

                          So I just tested this when I got home.
                          Taking a screenshot after I ran xrandr -o left in single desktop mode reveals that everything is rotated in the screenshot exactly as it should except that it is not what it looks like to the eye.

                          The result looks like running a virtual desktop. Black border to the right and at the bottom. So it is almost working. Can someone explain why the screenshot is rotated but the picture im looking at is not ? This should be fixable...

                          Trying to rotate in Big Desktop mode results in kernel panic or screens go to standby.
