I have two quadro RTX 4000 graphics cards, each connected to a monitor. My goal is to use the mosaic option to combine these two monitors into a unified desktop.
The operating system I am using is Ubuntu Keylin 22.04 Pro. Currently, there is an issue where if I do not enable the Basemosaic option, I can see two graphics cards and two monitors. However, if I enable the BaseMosaic option and restart the computer, and then use Nvidia settings, I can only see one GPU-0, which corresponds to only one monitor. The other monitor is in a no signal state.
May I ask what setting usually causes this? thank!
ubuntu22.04 and 24.04 have the same problem，I need help ，please…
