I am using the Cachy os with kernel 6.12.6-2 stable on my Lenovo P620 ThinkStation workstation.
I have two GPUS - both the same NVIDIA RTX A4000 workstation edition synced with PNY Quadra Sync card. Both work flawlessly under Windows 10.
When I connect both of my monitors TO THE SAME GPU - both monitors work ok.
When I connect one monitor to the first GPU and a second monitor to the second gpu I ONLY get the cursor displayed on my secondary monitor - but no desktop, no wallpaper, no windows when I drag them.
Both monitors are properly discovered by the system - but I cannot use the second monitor (and as a result my second GPU).
It is a bit problematic since having 8 outputs was the primary reason for me to have two GPUS in the same machine.
Any help would be appreciated.
