    A485 should have all of these. Using T430s currently, couldn't be more happy. Intel an a little bit old, but still rocks.

      Matter of taste I presume. I really like Lenovos keyboards, and as a developer can't live without PgU/D next to the arrow keys. Great for reading. There is print screen, between right Alt and Ctrl. Fkeys is a minor inconvenience, I agree. Ditching hardware speaker mute, volume +/-, and microphone mute is a wrong move to me.

        On my lenovo 310 (amd APU) you can swap the F-keys and multimedia keys in the UEFI settings, so that by default when you press F1 it does F1 and not "sleep" or whatever is its secondary function.

        Can confirm the haptic feeling isn't great on the 310, but then again it's fine for a 500-ish laptop anyway.

          Strictly speaking Mesa is for OpenGL acceleration and can optionally be used for other things (we put our video encode/decode drivers there for example), primarily when those "other things" share lower level driver bits.

            Sounds like the right place for Vulkan to me.

              Mesa is not for 3D acceleration, what about VDPAU, OpenMAX and all that stuff? is it 3D acceleration? What about using Mesa for 2D stuff in OpenGL?
              And even if it was, so what?

                No because amdvlk is not a community project. It was made by AMD for AMD to develop. It's source doesn't even have any git or any kind of repository management.

                  Until AMD discontinues their code dump method, it's going to get backlash. That's a very unfriendly thing to do.

                    Just don't gimp it with single-channel memory, spinning drive, crappy screen, or small battery.
                    Good advice!

                      Yep, I totally agree. Back in 2007 when AMD really committed to open source the only reason they could was because of community based projects. I just don't get them, their own early involvement happened because they were able to make themselves part of the community. They know how important collaboration is yet when they get a chance to break free from pre-existing dogma they choose a distribution model that makes collaboration really hard. WTF.
