    thats why i use opensource drivers for radeons, its ok imho, yea 3d is kind slow in some games via vine, but they are good in normal use [not gaming]

      ATI 5870 on Ubuntu 10.04, The Saga Begins.

      • Boot system while the nVidia 9800GT is installed.
      • Downlod the ATI 10.6 fglrx driver.
      • Removed its driver.
      • Rebooted to confirm it's thoughorly removed.
      • Shutdown the system.
      • Removed the 9800GT and installed the 5870.
      • Power on the system
      • Machine boots to GDM and then onto the desktop using the open drivers with no problems.
      • Launch a shell.
      • Execute the fglrx installer.
      • Its GUI is displayed.
      • I select build packages and follow the prompts.
      • The environment is correctly identified as Ubuntu/Lucid.
      • Says it built the package but it doesn't actually build them.
      • I exit the GUI.
      • It then autostarts the installer in text mode in the shell I launched it from for some reason.
      • I go through it again just for laughs.
      • It crashes due to a double free. WTF?
      • I look at the log. It says there's no dpkg-buildpackage so I install dpkg-dev and try again.
      • This time the installer does something but still fails.
      • Installer log says it needs the dh command.
      • I install debhelper and try again.
      • Fails again due to not having execstack available.
      • I install execstack and try again.
      • This time it builds the packages.
      • I install the packages. They install without issue.
      • I remove the old xorg.conf and execute '/usr/bin/aticonfig --initial -f'.

      And here it gets interesting.
      I'm presented with this wonderful output:

      [email protected]:~/Downloads/fglrx$ sudo /usr/lib/fglrx/bin/aticonfig --initial -f
      Unable to open /etc/ati/control, please reinstall the driver.
      /usr/lib/fglrx/bin/aticonfig: [B][COLOR="LemonChiffon"]No supported adapters detected[/COLOR][/B]
      lspci -v provides this output:

      01:00.1 Audio device: ATI Technologies Inc Cypress HDMI Audio [Radeon HD 5800 Series]
      	Subsystem: Giga-byte Technology Device aa50
      	Flags: bus master, fast devsel, latency 0, IRQ 17
      	Memory at e5020000 (64-bit, non-prefetchable) [size=16K]
      	Capabilities: <access denied>
      	Kernel driver in use: HDA Intel
      	Kernel modules: snd-hda-intel
      At this stage I wonder if I've got a card that fglrx doesn't have PCI ids for.

        ATI 5870 on Ubuntu 10.04, The Saga Continues.

        On further investigation, the packages built by the installer are full of fail. Note to others, be wary of that path.
        • Just for laughs I decide to remove the built packages, reboot and re-run the installer but this time I choose to install the drivers directly from the installer.
        • This succeeds.
        • I run '/usr/bin/aticonfig --initial -f' and this time it succeeds as well.
        • I reboot and get to a desktop with cloned displays. (Both screens display the same image)
        • I run 'gksudo amdcccle' and configure the system for one desktop accross two displays.

        After a restart I'm presented with one screen correctly displayed and one screen which is black. The mouse pointer happily moves onto and around that screen and back to the other one but when dragging a window onto it it is not displayed. This 'black screen' issue is not unheard of unfortunately.

        • After various bits of mucking around I shut down the system,
        • install another hard drive,
        • do a clean install,
        • install all available updates,
        • reboot,
        • Install the distro provided 10.5 drivers,
        • reboot,
        • configure the display for one desktop accross two screens,
        • Log out, and back in.
        • I'm presented with what I'm after.

        At this stage, with the 10.5 drivers the system displays the well known slow maximise behaviour but other than that during this very short bit of the test no other bad behaviour is encountered. I should stress though that I didn't spend much time in this environment.

        After satisfying myself that the hardware is able to provide this dual screen functionality that I'm after, at least with the 10.5 drivers, I'm a bit happier.
        • I remove the 10.5 drivers,
        • reboot,
        • install the 10.6 drivers,
        • reboot,

        After the system successfully boots to the cloned desktop with the 10.6 drivers I configure the system for one desktop accross two screens.
        After a reboot for thoughourness I'm presented with a desktop with one desktop accross two screens. Just what I'm after.
        Compiz is functional and fast.

        At this stage I'm even happier and now decide to correct my original install on the SSD.

          ATI 5870 on Ubuntu 10.04, Finally success.

          • I shut down the system and remove the HDD,
          • install the SSD, configure the machine to boot from it,
          • boot to my original desktop
          • am again presented with the black screen issue.

          I re-install the 10.6 drivers and muck around a bit, fight some with amdcccle and then after a few reboots I'm presented with a correctly behaving one desktop accross two monitors configuration within my original system installation.
          • I now enable vsync.
          • I make sure compiz is configured to use vsync.

          At this stage I can confirm that vsync for multi-monitor configurations is indeed broken in 10.6
          I'm unable to get the system to vsync. Not for the desktop, and not for GL ouput of video from player. I was aware that this would be likely from previous posters. It's a problem that afflicts multi-monitor configurations with 10.6 but not with single screen configs.

          vsynced video was not a problem from these screens on the 9800GT. That lack of vsync is one issue I'm prepared to live with for a short while. I hope it's fixed in 10.7 or 10.8.

          The slow maximise behaviour is no longer here. A win for 10.6

          The random black bits in windows is however here. Again, I'm prepared to live with this for a while as I was aware that it was happening to others.

          So a bit of a summary.

          Aside from the random black window and vsync issues I'm currently satisfied with the outcome. I was prepared for some breakage though and a new Linux user may not be so forgiving of these issues as I am.

          One thing I will say though is that this card is really, really, really fast. Stupidly fast in fact.

          It was able to roughly double the frame rate of the 9800GT for the Unigine Heaven Demo. That is, the demo was running in a window (@1024x768) on a composited desktop on one screen, while the other screen was playing a full screen video stream, it doubled the 9800GT unredirected full screen @ 1024x768 doing only this frame rate.

          More on performance to come.

            If I didn't need to run three screens I to would've bought an nVidia card. I now need to acquire an active DP to DVI adapter to light up the third screen. Hopefully it works well.

              Do yo know anyone with access to a pre-release of 10.7 and a multi monitor setup? If so it'd be very interesting to see if they've fixed this as well.

              That makes me happy to hear.

              Looks like nVidia might be the second choice graphics platform for Linux users by the time the year is out. Will wonders never cease?

                its new to 10-7 ;-)
                Mostly I'm just curious if they've identified the source and rectified the issue where there seems to be no ability to perform vsync in a multi-monitor enabled setup.

                I haven't looked to deeply into that particular issue myself and am just putting up with it at the moment. It'd be great news if it'd been addressed already.

                  mugginz, question. I have an HD5850, and I get a single horizontal tear on my second monitor when I play a fast video or run glxgears. It might also appear on the primary monitor depending on your setup.

                  Can you test this on your system. Do you get a single line tear when playing a video, full screen on either monitors?
