Hi @851429603, welcoem to the NVIDIA developer forums to you as well.

The problem here is slightly different than with you, henadarr. Lookign at the log:

Oct 12 09:27:37 ubuntu kernel: [  146.858572] NVRM: API mismatch: the client has the version 535.113.01, but
Oct 12 09:27:37 ubuntu kernel: [  146.858572] NVRM: this kernel module has the version 515.43.04.  Please
Oct 12 09:27:37 ubuntu kernel: [  146.858572] NVRM: make sure that this kernel module and all NVIDIA driver
Oct 12 09:27:37 ubuntu kernel: [  146.858572] NVRM: components have the same version.

The kernel module was not upgraded correctly. Which is easily explained by this message that came up during installation:

-> An alternate method of installing the NVIDIA driver was detected. (This is usually a package provided by your distributor.) A driver installed via that method may integrate better with your system than a driver installed by nvidia-installer.

Please review the message provided by the maintainer of this alternate installation method and decide how to proceed:

The NVIDIA driver provided by Ubuntu can be installed by launching the "Software & Updates" application, and by selecting the NVIDIA driver from the "Additional Drivers" tab.

In this case the best course of action is to purge all NVIDIA drivers and reinstall them from scratch either through “Software & Updates” or through the downloaded .run file. But please do not mix and match.

Thanks!

ubuntu kernel

Thank you very much. I have uninstalled and reinstalled all the drivers, but I have checked the dmesg and it shows an error in the following image. Can you help me take a look again?

[MarkusHoHo]

My guess would still be a kernel module mismatch or a failed kernel module compilation.

Did you reboot after purge and after installation?
Did you install using a .run file or the distribution way?

The image above claims version 535.104.05, but before you had 535.113.01

Thank you for your patient answer. @henadarr We have resolved the issue. Firstly, the Ubuntu 20.04 upgrade to 22.04 kernel conflict occurred. After uninstalling the previous kernel, there was a conflict between the integrated graphics card and the independent graphics card, which resulted in the Ubuntu desktop not being displayed and the independent graphics card not being driven. My solution is to first remove the NVIDIA driver and the independent graphics card and uninstall the Ubuntu desktop. After restarting, install the Ubuntu desktop. After displaying normally, install the graphics card and NVIDIA driver.
