My LG monitor cannot detect my laptop which using Ubuntu 20.04. I have nvidia 525 open source package. Any suggestions on fixing this? Thanks

Hi there @duygaomen and welcome to the NVIDIA developer forums.

The Open Source kernel modules are only supported on specific workstation systems.

Please Purge all installed NVIDIA drivers and re-install the proprietary driver package coming with Ubuntu 20.04 using the “Additional Drivers” tab in the “Software & Updates” tool.
