    Phoronix: Ubuntu 19.10 To Ship With Flicker-Free Boot Support

    Thanks to the upstream work achieved by Red Hat engineers working on Fedora the past few cycles, Ubuntu 19.10 should have a flicker-free boot experience...

    With amdgpu is still flickers in kernel 5.2 / Debian testing.

      Do Linux users really care that much about a little bit of flicker at the start? Of all the problems I've encountered in my life, I would rate this close to last place in priority, but maybe others see this differently?

        It's not about it being a priority, it's more about polish. Stuff that people don't notice unless it stands out.

        The fact that they are caring about this says lots about the current state of Linux on the desktop.

          weird, yes. But less important issues take less amount of work as opposed to the very complicated important ones

            Does this only work on intel?

              AMDGPU too. It works if you're using Mesa. I have an RX 560. I get less flicker than before, but it's still not flicker-free.

              But it seems to work better with Intel graphics, as the article says.

                For all 3 big heads and possibly else, chances are slim but not impossible



                Sans this, sans blobs, sans bugs

                1) I get a black screen for a couple of seconds during boot?

                1.1) If you have an AMD or Nvidia GPU driving your screen, then this is normal. The graphics drivers for AMD and Nvidia GPUs reset the hardware when loading, this will cause the display to temporarily go black. There is nothing which can be done about this.

                  Reliable wakeup when I open my laptop lid would be worth much more to me than flicker free ...
                  Every few times I open my laptop, it is just dead and I have to hold in the power to hard reset.

                    Not on Fedora 31, on a Ryzen laptop and a RX580 workstation
