Ubuntu 20.04 won't wake from suspend or completely shutdown

I'm running Ubuntu 20.04 on an Acer Thinkpad A475. Suspend and shutdown have stopped working properly. When I suspend, the laptop won't wake, forcing me to hold the power button until it turns off, then start it up again. When I try to shutdown or restart, the same problem happens. The screen goes black, but the power button remains lit and I have to hold the power button to make the laptop turn off.

I've been googling this problem for several days. One suggestion to diagnose the problem was to power down the laptop, wait a half hour, then forcefully power down by holding the power button, then after restarting, run sudo journalctl -b -1 -e. This is the result:

I've tried looking for missing drivers, with ubuntu-drivers devices, but the result is blank. I've seen that this could be also be a GPU or kernel issue. Any help you can provide in finding a solution would be greatly appreciated.

UPDATE Shutdown and Restart both work when booted into recovery mode, and suspend is closer to working. When booting into recovery mode I get a warning saying "some graphic drivers require a full graphical boot and so will fail when resuming from recover", so maybe this is a graphics driver problem? I've made sure my graphics driver is up to date. My graphics card is an AMD Radeon R7 Graphics and the driver is AMD GPU.

Tôi có cùng một máy tính xách tay và cùng một vấn đề. Đã cố gắng để tìm ra nó trong tuần qua. Kết quả tương tự trong nhật ký tắt máy. Đã dành thời gian để tìm kiếm các lỗi khác nhau trong nhật ký (cpufreq, lỗi ngắt kết nối đĩa, LUKS, fsck, v.v.), nhưng không tạo ra sự khác biệt. Tôi đã có thể hoàn nguyên về kernel 5.11.0.38 chung và mọi thứ đã trở lại bình thường. Phiên bản đó đã được tung ra khỏi grub nên tôi đã thêm nó trở lại đây.

xuất KERN_VERSION=5.11.0-38-generic
sudo apt install linux-headers-$KERN_VERSION linux-image-$KERN_VERSION linux-modules-$KERN_VERSION linux-modules-extra-$KERN_VERSION 

sau đó tôi đã đánh dấu cái này là một lưu giữ

sudo apt-mark hold linux-image-5.11.0-38-generic # Tôi nghĩ điều này sẽ ngăn nó tự động xóa

Sau đó bật grub để ghi nhớ kernel đã khởi động lần cuối. Có lẽ có những cách khác tốt hơn quá

sudo vi /etc/default/grub

# Thêm các cài đặt này
GRUB_SAVEDEFAULT=true
GRUB_DEFAULT=đã lưu

Bây giờ, không chắc điều gì thực sự sai với 41 và 43. Hy vọng có thể được sửa trong phiên bản mới hơn. Không thể ghi lại một lỗi thực tế sẽ chỉ ra nơi gửi báo cáo lỗi.
