shrisha I have an Nvidia card too, and when I installed Solus to my NVMe SSD I had to do some tweaking to get it right. First, I had a two monitor set up. One was HMDI and the other was DisplayPort. When installing I couldn't get any picture to the DisplayPort monitor, so I had to do the entire setup through my HDMI monitor. Second, I was having issues with making sure I was using UEFI, because my installation media kept trying to default to legacy, somehow. Ultimately, I had to add this to my grub for the installation before I could install the NVIDIA drivers: quiet splash acpi=off
I'm not sure if any of this will help, but I'm running an Intel i5-9600k (6) and NVIDIA GeForce GTX TITAN X with the latest Solus.
