    Was 14.04 dropped as well?
    Yes, as I said in my previous comments.

      • What's the highest OpenGL I can get with a Radeon HD 6850? Right now it's 3.3 by using "MESA_GL_VERSION_OVERRIDE=3.3COMPAT". Some games are starting to require OpenGL 4.0 and I'm not sure if this card will ever see support for it. I might have to grab something like a RX 460.

          Latest upstream drivers include 4.1 support, but you're limited to 3.3 without over-ride for now because your HW does not include native fp64 HW support. As long as you are running quite recent drivers you should be able to over-ride to 4.1 now.

          • Auto-moderated again... what I said in previous post was that you should be able to over-ride up to 4.1 with recent upstream drivers.

            Note that mesa drivers only support core profiles, not compatibility mode, so don't force compatibility over-rides unless you are sure the app "requests but doesn't actually need" compatibility support (mixing deprecated features with new features).

                What do you mean for core profile? when I search for vga capabilities I get core profile 3.3 but opengl profile stay at 3.0. So what value I have to consider?

                  • Anyone trying to use ppa-purge to remove this PPA on Mint will find it doesn't work unless you add -d <name of distro>. Works good on Mint 18. If you plan to upgrade to Mint 18 from 17, just use trusty instead of xenial before you do the upgrade.
                    Code:
                    sudo ppa-purge -d xenial ppa:oibaf/graphics-drivers
