  • Display brightness change shortcuts - brings up icon but it’s not functional
    Brightness can be changed by dropping to the login shell and updating brightness in /sys/class/backlight/amdgpu_bl1/brightness
    Hack:
    In dom0 terminal type:
sudo -i
cd /sys/class/backlight/amdgpu_bl1/
cat max_brightness
echo 100 > brightness
    For a permanent solution:
    In dom0 terminal type:
    sudo nano /etc/default/grub
At GRUB_CMDLINE_LINUX before "rhgb quiet" add acpi_backlight=native
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
and then reboot the machine keyboard shortcuts work as they should.
