[Solved] Success can only be achieved during the first sleep.

I have Windows 11 and Arch Linux installed on the same hard drive. Fast startup has been disabled in Windows 11. When I boot into Arch Linux and put the system to sleep (systemctl suspend), everything works fine. However, when I wake it up and try to sleep again, it fails (I have to shut down to successfully enter sleep mode), the screen immediately lights up or lights up after a few seconds. It's very frustrating when my laptop cannot enter sleep mode. Thank you in advance for your help. ?

Re: [Solved] Success can only be achieved during the first sleep.

I don't know why it works, but after adding mem_sleep_default=deep to GRUB_CMDLINE_LINUX_DEFAULT in the /etc/default/grub file, everything is fine.

```
GRUB_CMDLINE_LINUX="amdgpu.dcdebugmask=0x10 amdgpu.sg_display=0 mem_sleep_default=deep"
sudo grub-mkconfig -o /boot/grub/grub.cfg
```
