type sudo -H gedit /etc/default/grub
Find this line: GRUB_CMDLINE_LINUX_DEFAULT=""quiet splash""
Add acpi_osi= immediately following quiet splash to give: GRUB_CMDLINE_LINUX_DEFAULT=""quiet splash acpi_osi=""

Many thanks for the interesting post but it soesn't function for me.<br />
In the first start my laptop went locked because the post reports the file creation with double quotes but i believe it's a mistake so i deleted une of them and my laptop was able to start.<br />
With the editing of the grup file my only new was that the touchpad stopped to work.<br />
In both cases, however, the solution is not good for me.

Backlight keyboard activation on Asus Strix
How can i activate the backlight keyboard on my nb (Asus Strix Republic of Games) ?
Using Win10 the backlight is active and can be deactivated using FN-F3/FN-F4 but with ubuntu (i am using the Lubuntu desktop environment) the FN key seems not to be active and the backlight keyboard is always off.
