It is incredibly annoying to me that my mouse wakes the computer when I barely touch it. If I want my PC to turn on, I press the Super key.
I find very hacky scripts online, I tried some but they didn’t work. How did you disable it?
This option is missing from settings.
What system do you have? Laptop or desktop, if laptop which one, if desktop which mobo do you have? Check your bios for any sleep options, specifically S0 vs S3 standby.
S0 standby vs S3 standby can change things a lot. If you’re in S3 standby then it’s up to your bios/firmware to handle waking from sleep. If you’re in S0 standby then your OS is in control.
