Ubuntu doesn't wake up after standby

li flag

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

i have a ssd and a HDD with these partitions :

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
