I have a machine with two Nividia titan rtx and an integrated graphic cards.
The machine doe snot boot to GUI if any monitor connected to NVIDIA cards.it can boot to console.
if there is no monitor connected to the Nvidia card and only connected to the integrated GPU, Ubuntu 20.04 boot to GUI.
-I have Nivida-driver 440.100 installed and ubutnu setting tell that there is two TU102 [titan rtx]
-the prime-select is nvidia
- the nvidia-persistenced.service is running
but the dmesg has this error:
