My set up is a workstation with 3 ubuntu studio 20.04/xfce, one with Darktable, gimp 2.99 & without others software packages not devoted to photography, the 2 others are devoted to sound/video or photogrammetry (Colmap+meshlab+cuda). I avoid kde/qt based softwares, plasma has some conflicts with thunar, & color calibration related softwares. The lowlatency kernel is useful with gimp + xp-pen tablet (no retouching’s latency), as in sound, video & photogrammetry. I use 2 nvidia graphic cards in depth 30 (10 bits) & 2 monitors. Only xfce works with 2 graphic cards & 2 monitors + different calibration to each monitors. The NAS use openmediavault. I can mount in terminal, the samba share with smb:ip, the fastest but not visible in RPD & with mount -cifs, visible in RPD, but 10 times slower. I use a switch in 1000 baseT. With darktable, i can reach the share at the fastest speed, not with RPD.
