I have the last version of Ubuntu. When my computer goes in standby because I don't use it, I was not able to wake it up. If I move my mouse or touch my keyboard, the screen wake up and show a red/orange (Ubuntu color) but nothing else and I need to shut down the computer by staying on the on/off button and start up again... Any solutions ?
When I use it and choose "suspend" and try to wake up just after it works but i wait too long it doesn't work.
config of the computer (it's a custom):
cpu : AMD Ryzen Threadripper 2990WX 32-Core Processor
motherboard : X399 AORUS PRO-CF
graphics : GeForce RTX 2080 Ti
RAM : DIMM DDR4 Synchronous Unbuffered (Unregistered) 2133 MHz (0.5 ns
