    Agreed, there's perfectly good old laptops and desktops that still function...maybe there needs to be a xserver-legacy-1.11 branch with someone who could step forward to maintain the older X server along with the classic drivers. If enough people say something maybe the X developers can look into what's doable.

    Also what about the Radeon 7500-9000 series that use the R100~R200 drivers? I have 2 thinkpads that use these graphics chips and I'd like to keep using them with Linux

    This is hyperbolic. the effected cards are absolutely ancient, and one cannot reasonably expect such old hardware to keep being supported with a modern OS.

    The problem is most of these old cards don't have the necessary hardware bits to actually accelerate much that a modern desktop uses. Some of them are not even capable enough to support the bare minimum required for EXA. You'll get better performance using shadowfb (albeit with slightly higher CPU usage) than using the actual 2D hardware in most cases. We are talking about 10-15 year old cards here...

    It looks that some porting will be needed to bring back support for older devices with EXA. I have still machines using cirrus, s3, s3virage, neomagic and trident drivers. I understand XAA must be removed, and I fully support this move. But I was always so proud that Linux kernel and X.org server supports so much devices without installing any additional drivers or manual compilation. Now this advantages is going to die.

    Nonsense, because the X11 protocol has nothing to do with changes in the driver architecture. XAA, EXA, and friends are simply parts of the Xorg implementation of that protocol.

    Yeah, it's sad... I have an Alpha that I was going to set up with a 3DFX Voodoo3 in the near future. Looks like I'll have to restrict myself to older versions of X.org if I want a working non-VESA driver. That, or I finally have to learn X driver development and figure out how to port the voodoo driver to EXA, and possibly KMS/DRI2...

    Wasn't someone actually working on a KMS driver for 3dfx cards a few years back as part of a documentation GSoC project?

    i'm glad to see a lot of this old stuff taken out. i'm starting to feel like its time to move onto X12 though, now that X11 is gradually becoming incompatible with it's own drivers. X11 has been around for a really long time. if you have old devices that use these old, removed drivers then it is going to be difficult to find the last version that supports it. i'm not really sure why X11 has been around for as long as it has been. i'm sure the very first release of it has enough missing features that it'd be incompatible with modern desktop environments.

    The XAA 2D acceleration architecture is finally set to be stripped out of X.Org Server 1.13 and upstream open-source X.Org drivers...
