Dell xps 15 9570 problem with hotkeys F11 and F12 for brightness [SOLVED]
Announcing the arrival of Valued Associate #679: Cesar Manara
Planned maintenance scheduled April 23, 2019 at 23:30UTC (7:30pm US/Eastern)Brightness problem Ubuntu 18.04 LTSUbuntu 12.04 - Brightness controls not workingI don't have notifications when changing the brightnessBrightness not changing Dell 15r SE and ubuntu 12.04Ubuntu 14.04 LTS: FN-Brightness Key Stopped WorkingUbutnu Screen Flickering after Changing BrightnessUbuntu brightness max_levelBrightness Problem Ubuntu 15.10 (Dell inspiron 5737)screen brightness keys stopped working — ubuntu 14.04 LTS — HP notebookBrightness control Ubuntu 16.04Brightness on laptop MSI GT72VR in Ubuntu 18.04 with NVIDIA GTX 1060 Mobile doesn't work

}
I installed Ubuntu 18.04.02 LTS, initially I had the problem of not being able to manage the brightness, neither through the hotkeys F11 and F12 nor through the control panel at the top right, (where there is also the switch-off button).
I followed the answer suggested by Ducky (here Brightness problem Ubuntu 18.04 LTS), in particular the second solution (acpi_backlight=video). This allows me to correctly change the brightness from the top right menu, but it still does not allow me to change the brightness using the Fn+F11 and Fn+F12 shortcuts.
What might it depend on?
[solved]
I solved by going to edit the /etc/default/grub file by putting the following lines:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi"
GRUB_CMDLINE_LINUX=""
shortcut-keys dell brightness
