After three years decided to upgrade my GTX750Ti which did not have a DisplayPort interface to a GTX1650 which does a DisplayPort. As I periodically upgrade the Solaris x86 Driver was running 450.51 without any problems using the GTX750Ti card. Powered off, swapped the 750Ti for the 1650. Power on, POST completed normally, OpenIndiana started normally until it got to the point when it needed to start LightDM GUI Login when the computer rebooted no error was displayed. With the 1650 still installed booted to single user mode and installed the 450.57 driver and rebooted. OpenIndiana rebooted when it tried to start LightDM. To verify it was not a hardware issue, disconnected all data drives, swapped boot disk for temporary replacement and installed Linux which identified the card and the system worked normally. Swapped the GTX1650 for the GTX750Ti and Opendiana booted normally and was accessible via LightDM GUI
Switched to GTX1650 used Solaris Driver NVIDIA-Solaris-x86-455.28.run and found that if I left my workstation eventually Lightdm does start but it can take between 1 - 12 reboots. If I attempt to upgrade the Driver to NVIDIA-Solaris-x86-455.38.run or NVIDIA-Solaris-x86-455.45.01.run the system panics and core dumps. See attached
When I run a scanpci on my system it can identify the following :-
pci bus 0x0004 cardnum 0x00 function 0x00: vendor 0x10de device 0x1f82
NVIDIA Corporation TU117 [GeForce GTX 1650]
pci bus 0x0004 cardnum 0x00 function 0x01: vendor 0x10de device 0x10fa
NVIDIA Corporation Device unknown
I have googling the device id for the unkown device, for this to be correctly identified is an updated driver required. This may be difficult to install given the panic and coredump with the last two driver updates
