    Phoronix: Intel Graphics Driver Low-Latency Scheduling Revived For A Smoother UX

    For the better part of a year now we've seen patches for Intel's kernel graphics driver working on fair low-latency scheduling that in part has been inspired by the design of BFS/MuQSS. While it's too late for seeing the work land with Linux 5.12, the latest batch of 57 patches were sent out this week...

    It seems there is still no output brightness levels control in sysfs as an equivalent to xrandr functionality, so it would be required for each Wayland compositor to implement an option that is based on a shader? And other display configuration settings are done by the Wayland compositor too. Then why do we need a control panel in 2021 that will be pointless for important display matters?

      Article is about Intel graphics driver, not wayland. The intel graphics driver also provides backlight control. Which is a better solution to manage brightness because it actually changes monitor brightness. color management (What you'd call xrandr) is indeed absent from the wayland protocol, which should be included at some point. Display configuration settings are also absent from both wayland and compositors because most of them are implemented by the driver.

      Which might change once intel implements their control panel and allows linux users to configure their display.

        In sway display resolution is managed by sway itself, so indeed it compositor’s work (wlroots?). Backlight can be controlled via sysfs or an equivalent abstraction (light...). Works well here.

          I will always believe that iGPU 7gen is "decent" GPU but is limited by driver in both win/Linux oven on macOS
