I have recently purchased a ROG Falchion RGB wireless keyboard for use with my dual boot desktop (Win 10/Ubuntu 21.04). In Windows, using Armoury Crate, I have configured the lighting and set the power options for the keyboard to sleep after 2 minutes of idle time. What I have found is, when using Ubuntu, after the idle time has expired, instead of the keyboard going to sleep, the entire system goes into hibernation and the OS will restart unless you wake it and cancel the reboot. Currently, the only option to resolve the issue is to turn off the keyboard's power saving options in Armoury Crate. As this is not ideal, does anyone have any advice or thoughts on keeping power saving options on without causing the shutdown issues in Ubuntu?
