Basically the title says it all.
I have brand new Asus Rog Strix with AMD Ryzen 9 and Nvidia RTX 3070.
After the initial install of Ubuntu MATE 20.04 it is working fine with the Nouveau driver. However, if I install the nvidia driver (manually or via the package manager), I always end-up on black screen after reboot. Tried every solution I have found, but nothing works. At least I am able to get in the console and generate bug report.
Your kernel is too old for the amd gpu. Please upgrade your hwe https://wiki.ubuntu.com/Kernel/LTSEnablementStack and do a full system update afterwards. This should give you the neccessary kernel and driver versions.
Hey, @generix , thanks for your response. I did a clean install of ubuntu mate 20.04.02, which uses kernel 5.8.0-41, but still no luck. Exactly the same issue. Attaching the new bug report
You have a driver mismatch
Feb 6 08:47:48 predte4a-dev kernel: [ 4.238258] NVRM: API mismatch: the client has the version 460.39, but
Feb 6 08:47:48 predte4a-dev kernel: [ 4.238258] NVRM: this kernel module has the version 460.32.03. Please
Feb 6 08:47:48 predte4a-dev kernel: [ 4.238258] NVRM: make sure that this kernel module and all NVIDIA driver
Feb 6 08:47:48 predte4a-dev kernel: [ 4.238258] NVRM: components have the same version.
Please purge and reinstall the driver.
Hey, @generix , thank you very much for your time, but I`m really confused right now. If I do
âubuntu-drivers listâ
I get
ânvidia-driver-460, (kernel modules provided by linux-modules-nvidia-460-generic-hwe-20.04)â
However, If I do
âsudo apt install --install-recommends linux-modules-nvidia-460-generic-hwe-20.04â
I get:
The following packages have unmet dependencies:
linux-modules-nvidia-460-generic-hwe-20.04 : Depends: nvidia-kernel-common-460 (<= 460.32.03-1) but 460.39-0ubuntu0.20.04.1 is to be installed
E: Unable to correct problems, you have held broken packages.
So I have to install
linux-modules-nvidia-460-5.8.0-41-generic, cause this looks like the right modules for my kernel. But if I do so you say there is a driver mismatch⊠frustrating stuffâŠ
In the repo I see only one package about 460 and it is nvidia-kernel-common-460. If I install it it turns out to be:
Unpacking nvidia-kernel-common-460 (460.39-0ubuntu0.20.04.1)
What should I install after all and is there some documentation about this thing?
according to the logs, you still have ânomodesetâ set, please make sure it is removed from grub config and run
sudo update-grub
then reboot. After reboot, please check if Ubuntu system info reports
âAMD Renoirâ
as graphics device.
If thatâs the case, you can use Software&Updates to install the nvidia driver.
Hey, @generix ,
Ubuntu shows that the packages you mentioned are already unistalled. I updated the grub, but the graphics used are
âlvmpipe (LLVM 11.0.0, 256 bits)â
Iâm sorry, I only now saw that youâre on a brand-new Ryzen 5900, those are only supported by kernel 5.10+. Youâll have to install that manually:
You will need 4 packages
linux-headers-XX
linux-headers-XX-generic
linux-image-unsigned-XX-generic
linux-modules-XX-generic
from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10.14/
Afterwards, please check if the correct AMD graphics is displayed
@predte4a, did you solve it? I have the same Asus (Ryzen 5900, RTX 3070 mobile) with the same issue.
When I tried kernel 5.10.14 with 460.39 a screen was black, I heard login screen loaded sound, but no picture at all.
@sano1982 , no luck for me yet. It looks like we both have exactly the same issue. @generix , I installed 5.10.14 kernel, but when I boot I get error:
nouveau 0000:01:00.0: unknown chipset (b74000a1)
and the boot hangs.
If I put ânomodesetâ to the kernel parameters the OS starts normally, but again it is using
âGraphics: lvmpipe (LLVM 11.0.0, 256 bits)â
Can you switch to a vt using ctrl+alt+f4 when the boot hangs? You could then create a kernel log using
sudo dmesg > kernel.txt
Alternatively, boot to hang, reboot setting ânomodesetâ parameter and run
sudo journalctl -b-1 --no-pager |grep kernel >kernel.txt
and attach kernel.txt. Maybe some firmware files are missing/incorrect.
Hey, @generix , when the PC hangs on boot it is not responding, so ctrl+alt+f4 is not possible.
However, I got into recovery mode and here is the result of âsudo journalctl -b-1 --no-pager |grep kernel >kernel.txtâ
Ok, the amd firmware is missing. AFAIK, the gpu of the 5xxx series will be called Cezanne, a descendant of the 4xxx Renoir gpu. Currently, it has the codename âGreen Sardineâ so the driver tries to load green_sardine firmware. Which has not been publicly released by lazy AMD (the driver was added back in october).
So itâs now hunting for the firmware files.
Hey, @generix ,
No luck yet. I have added these files to /lib/firmware/amdgpu.
I made sure they have the same owner and permissions as the other files in the dir.
However, without nomodest to the kernel again it hangs with
