  • Was 14.04 dropped as well?

    Comment


    • Hi oibaf, thank you for the graphics driver, working great on my Surface Pro 4 i5. I know this may not be the place for this but I am using Peter Hunt's kernel and I noticed as of late, the cover type keyboard stops responding if it is remove or system goes to suspend... Do you know of any fix or workaround for this issue? Do you know what forum I can discuss this issue on? This was working fine a few kernel update revisions ago.

      Cheers

        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 u mean for core profile? when I search for devices opengl capabilities I get core 3.3 but opengl profle stay at 3.0

                    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?
