I used the dc7700 in a GNOME QA-test and got a response from vanvugt https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1930945/comments/5
"Yes this looks like a nouveau kernel driver bug. I recommend using the proprietary Nvidia driver instead, but it seems your GPU only supports driver version 340 and that's now too old to be supported in Ubuntu 21.10. So to continue using the "nvidia quadro nvs 290" you should probably install Ubuntu 20.04 instead where it is still supported.
