ubuntu24.04，rtx4000
I am currently using two RTx4000, with two DP interfaces on each graphics card, connecting a total of four identical displays. I used Mosaic to assemble these four monitors into a large screen. Now, due to some special applications, I need to use the command line to disable two of these four displays. Is there a feasible solution?
I have an NV-CONTROL extension 1.29, and I can set 2 screens (2 enabled, 2 disabled) to enable using the command line nv control dpy – add metamode “xxxxx” to achieve complete splicing of 4 displays. However, I cannot use nv control dpy – delete metamode “xxxx” to turn 4 enabled displays into 2 enabled displays. After executing the command, I will prompt “failed”. If possible, how should I write this command? If there is a higher version of NV control extension or other similar software that can be used, can you provide a download link? Thank you.
