with it:<br>
Kernel groups<br>
System D<br>
Nvidia<br>
And gues: Everyone says it's not their fault.<br>
<br>
But we don't give up. Linux is such a beautiful and solid system. Why <br>
would it work with Windows and not Linux?u<br>
<br>
Our analysis has now discovered that the problem does indeed come from <br>
the kernel. The kernel does not allow several users to access a graphics <br>
card at the same time. Indeed, to use it, several users need access to <br>
the graphics card at the same time.<br>
<br>
Can this simultaneous access be allowed by the kernel after all?<br>
Or can the kernel be adjusted so that this would be possible?<br>
<br>
In the meantime I am also working with a multiseat company to search <br>
together for a solution for multiseat under Linux. This company is <br>
working on creating an easy and user-friendly program to work via a <br>
multiseat with Linux, and they have already a high-selling multiseat <br>
program for Windows. The intention would be to create a program that <br>
works like some multiseat programs in Windows: install, drag mice and <br>
keyboards to the right screen, restart and it works as multiseat.<br>
But such a program is only interesting if it can work for different <br>
users on 1 video card. For example, for a multiseat of 6 users you need <br>
3 video cards with 2 outputs each.<br>
For now the programmers has a good béta program, but with the <br>
restriction only one workstation on one video card, but then it's not <br>
interesting at all.</blockquote><div><br></div><div dir="ltr">You don't mention which GPU you have. Pre-Kepler GPUs can only scan out 2 outputs at a time, so even if you have 3+ connectors on the board, you can still only have 2 of them active at a time. This is a hardware restriction. Kepler+ enables 4.<div><br></div><div>If you check "lspci -nn -d 10de:" it should give you all the NVIDIA hardware in your machine.</div><div><br></div><div>Cheers,</div><div><br></div><div> -ilia</div><div><br></div><div>P.S. Looks like I provided this very same advice to you without response on Jan 16, 2024. So it's an annual thing?</div></div></div></div>
