Same bug in Linux Mint 20.3 Una on Tuxedo Aura15 Gen1. After upgrading to
kernel 5.13.0-25-generic I get white noise instead of login-screen after waking
up from suspend or after screen was turned off due to power management. This is
also present in 5.13.0-27-generic. This has happened also one time directly
after booting, akin to description of similar/same(?) bug #1952155 here:
