When computer comes back up, launch System Preferences > Displays and you should now see the brightness option that was once hidden More Less. Restart computer ( this was the key step for me) 4. 2 the screen birghtness does adjust, however the screen returns to whatever brightness the screen was at before seconds later. Plug in power, mini-display, AND USB from the Cinema Display into MBP. If I run xrandr -output eDP-1-1 -brightness. The xbacklight commands do not work while the keys/slider are working or after.ĭoing some google dives I read up on xrandr and decided to try that. Once the keyboard keys and slider stop working (after I wake the computer from sleep) I can update /sys/class/backlight/intel_backlight/brightness manually and it still updates /sys/class/backlight/intel_backlight/actual_brightness, however the screen brightness does not change. I can verify that when the brightness keys are working, they update the values in /sys/class/backlight/intel_backlight/brightness and /sys/class/backlight/intel_backlight/actual_brightness. Running xbacklight -inc or xbacklight -dec. The Brightness slider from the GNOME top bar. The brightness keys on keyboard (Fn + F5, Fn + F6). However, after I close the lid of the laptop and open it back up, I am unable to adjust the brightness using the following methods: Upon booting the laptop I can adjust the brightness using either Intel graphics or Nvidia graphics. Running Pop_OS 18.04, clean installed when I switched from Ubuntu 18.04 that the laptop was shipped with. I'm on an oryx pro (Model: Oryp4) with a 17" display and an NVIDIA GeForce GTX 1060 graphics card. Thought I would reach out here and see if anyone else has encountered the issue/see if there is a fix. Hi, just purchased a new Oryx Pro and I'm having a little trouble.
