Realtek RTL8852AE issue on Lenovo Legion 5 Pro 16ACH6 (Ubuntu 20.04)

lá cờ cn

I have an issue on my new Lenovo Legion 5 Pro 16ach6 with its wifi card : Realtek RTL8852AE - PCIe 2.0 with ubuntu 20.04 and the 5.12.9 kernel (it's work on Windows 10).

I followed this topic : Network driver for Realtek 8852 20.10 but Modeprobe doesn't find the module "rtw_8723de" (which doesn't exist, I think It's a mistake in regards to rtw88 repository) and the 2 .ko created doesn't work : rtw89core.ko or rtw89pci.ko (we can see it in the lspci).

I tried different kernels like 5.8, 5.11, 5.12 but I have the same problem. Ubuntu 20.04, 21.04, the last Manjaro with gnome... I think its ok in the bios : I disabled secure boot and an AMD protection for CPU and no results ! There is an option with "discrete" and "dynamic" graphics but except a choice between the AMD graphic chipset and the NVIDIA video card, I have no difference.

When I try this solution : https://github.com/lwfinger/rtw89, I have this :

Update The log :


    sudo modprobe rtw89pci
    sudo dmesg | grep rtw

Update I have an UEFI Dual boot with EFIs partitions (I start on Ubuntu EFI with grub). Hibernate mode is disabled on Windows and I shutdown with restart mode for it. Bios information :

AMD Platform Security Processor : Enabled (If I disable that, I have nomore bluetooth and no wifi)
Device Guard : Disable
Secure boot : Disable
Secure boot status :  Disable
Platform Mode : User
Reset to setup mode
Restore Factory Keys

Update I tried this solution too :

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad.conf

Update When Ubuntu is starting, I have these messages (quickly) :

ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.PB2],
AE_NOT_FOUND (20210105/dswload2-162)
ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20210105/ps

Update 2 I tried all of these methods but no wifi :

Update 3 Now, when I want disable the module, I can't anymore if I use the wget solution :

sudo modprobe rtw89pci 
Erreur de segmentation (core dumped) # segmentation fault
sudo modprobe -r rtw89pci 
modprobe: FATAL: Module rtw89pci is in use.

Update 3 Same thing for the copy solution of the .bin (make) to the/lib/firmware/rtw89 :

sudo modprobe rtw89pci 
Erreur de segmentation (core dumped) # segmentation fault
sudo modprobe -r rtw89pci 
modprobe: FATAL: Module rtw89pci is in use.

Update 3 Disable the fast boot on Windows didn't work. I used a powercfg.exe /hibernate off to disable this mod ever (option disapear). But I tried to enable that to uncheck the option fast boot but it didn't change things.

Update 4 Ok I removed an error at the beggining of the session when I checked "Reset to setup mode" in the bios. But no wifi. After that, I reinstalled Ubuntu to be safe and I stay on the kernel 5.8.0.43 (there is 2 kernels with the 20.04 : 5.8.0.55 by default doesn't work, no boot).

integrity: Problem loading X.509 certificate -65

Update 5 Many peoples have the same problem (on arch mainly : no surprise because it didn't work on Manjaro). The conversation continue here (I continue to tell you if there are interessant news) : https://github.com/lwfinger/rtw89/issues/2

Update 6 The new version of rtw89 works very well for Ubuntu 20.04 and 21.04. Problem solved.

Hãy thử `cd /lib/firmware && Sudo mkdir rtw89 && Sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/rtw89/rtw8852a_fw.bin` Sau đó khởi động lại

Vui lòng thử tắt khởi động nhanh trong Windows: https://wless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled

Tôi chỉ nhận thấy rằng mã trình điều khiển vừa được cập nhật vài ngày trước. Bạn đã tải xuống mã nguồn trình điều khiển khi nào?

cam kết cuối cùng. Tôi đã thử cái khác ngay trước đó nhưng có vấn đề với quá trình biên dịch khi tôi sử dụng phiên bản 5.8. Hôm nay tôi cài đặt lại Ubuntu (để an toàn) và tôi sử dụng kernel 5.8 (chính thức)

Tôi nhận thấy rằng phần sụn mới hơn tại lwfinger git. Hãy chắc chắn để sử dụng cái đó.

Tại sao nó lại nằm trong /usr/lib/firmware/rtw89?
Matthmatth03 avatar

Tôi có một nghi ngờ về điều đó. Tôi đã thử 2 nơi và khi tôi thực hiện lệnh của bạn, tôi đã đặt nó vào trường hợp này. Tôi luôn thử cả hai. Tôi không hiểu sự khác biệt thực sự. Tôi cũng thử trong thư mục rtw89 và ngay bên ngoài.

Gần đây tôi đã cài đặt `linux-oem-20.04d` (thông qua apt) hiện nhận dạng và tự động tải mô-đun rtw89pci khi khởi động - không cần thực hiện thêm hành động nào.

Cập nhật gần đây `linux-generic-hwe-20.04` (5.13.0.25.26~20.04.12) hiện cũng cung cấp rtw89, không cần `linux-oem-20.04d`!

Mô-đun được xây dựng có tên là rtw89pci.

LD [M] /home/user/Documents/git/rtw89/rtw89pci.ko

Vui lòng thử:

sudo modprobe rtw89pci

Nếu mạng không dây của bạn không bắt đầu ngay lập tức, hãy kiểm tra nhật ký:

sudo dmesg | grep rtw

Và đăng kết quả.

CHỈNH SỬA: Bạn đang thiếu chương trình cơ sở cần thiết:

Tải phần sụn trực tiếp cho rtw89/rtw8852a_fw.bin không thành công với lỗi -2

Ngoài phương pháp tuyệt vời của Jeremy trong nhận xét của anh ấy ở trên, tôi đề nghị:

sudo mkdir /lib/firmware/rtw89 
Sudo cp ~/Documents/git/rtw89/rtw8852a_fw.bin /lib/firmware/rtw89 
sudo modprobe -r rtw89pci 
sudo modprobe rtw89pci

Có cải thiện gì không?

Phiên bản mới của rtw89 hoạt động rất tốt cho Ubuntu 20.04 và 21.04. Vấn đề được giải quyết.

Đăng câu trả lời

Hầu hết mọi người không hiểu rằng việc đặt nhiều câu hỏi sẽ mở ra cơ hội học hỏi và cải thiện mối quan hệ giữa các cá nhân. Ví dụ, trong các nghiên cứu của Alison, mặc dù mọi người có thể nhớ chính xác có bao nhiêu câu hỏi đã được đặt ra trong các cuộc trò chuyện của họ, nhưng họ không trực giác nhận ra mối liên hệ giữa câu hỏi và sự yêu thích. Qua bốn nghiên cứu, trong đó những người tham gia tự tham gia vào các cuộc trò chuyện hoặc đọc bản ghi lại các cuộc trò chuyện của người khác, mọi người có xu hướng không nhận ra rằng việc đặt câu hỏi sẽ ảnh hưởng—hoặc đã ảnh hưởng—mức độ thân thiện giữa những người đối thoại.
