    Phoronix: X Server 1.11 Breaks The Video Driver ABI

    While not exactly uncommon for a major X.Org Server update, the video driver ABI for the DDX drivers will break with the forthcoming xorg-server 1.11 release. This means that for those using the proprietary graphics drivers, namely the AMD Catalyst driver, you may be stuck waiting a couple of months for support...

    I didn't see a quick link to what improvements are in xserver 1.11 and whether I'll actually care if I can't use it.

      Oh man, breaking the ABI over some wasted bytes? Is that really worth it?

        I think it's not worth it. In fact it is really stupid to give away so much and benefiting so little from this change.

          "...for those using the proprietary graphics drivers... you may be stuck waiting a couple of months for support."

          Yeah, because all the X development happens behind closed doors, so there's no opportunity to build for the changes until the last second. Oh no, wait, that's a lie. The proprietary driver developers can pick up the code at any time and add a few tests, so that the same blob works on either release. If their code isn't working on day one, it's not the Xorg developer's fault, it's the fault of Nvidia and AMD.

            Note that's the first commit that changes ABI from xserver-1.10, but it's not the only one, and reverting just it would still leave the ABI incompatible.

              The next Xorg server version breaks the driver ABI, requiring users to wait for updates to proprietary drivers before upgrading the server.

              In other news, the Earth rotated today, creating a wave of darkness that required most of the planet's population to cease major work and travel activities for some 8 to 12 hours.

                Who said it's the fault of Xorg devs?


                I think the Catalyst devs have better things to do than making their drivers work with the latest Xorg 1.11 code, such as making it work properly with the current Xorg.

                  Since Microsoft has forbidden AMD to release Linux drivers sooner than Windows ones, that's to be expected. If AMD had some balls, this wouldn't be happening.

                    Just update the freaking driver code and recompile, AMD and nVidia....

                    Wayland is compatible with nothing at this time and if X.org can't even change such a minor problem than you can bet your X.org ass that Canonical is going to ship Wayland a lot sooner (they said they'd ditch the proprietary drivers whenever FLOSS becomes useful enough for them).

                    And you know what time it is when Ubuntu starts changing...
