I did a fresh install of 19.2 XFCE 64bit on a box with an Nvidia Quadro K1200 (PNY Graphics Card VCQK1200DP-PB) having booted off of the live media and selecting the first option "Start Linux Mint". Everything works great. After the install I reboot off the disk and everything comes up fine. The screen is a 4K screen and the resolution is automatically selected correctly.
When I do the same thing from the live media for 19.3 XFCE 64bit (ie, select the first option "Start Linux Mint") the screen eventually does momentarily show a resolution appropriate display of the new lm logo but then goes black. However, a ctrl-F5 gets me to a command line.
When I reboot off the live media and select "start in compatibility mode" the desktop does come up and I am able to do the install. Alas, after the install is done and I reboot the desktop crashes (I'm assuming so because the screen goes blank but I can do ctrl-F5 to get the command line.)
I'm happy to help in any way that I can.
The following output was collected from the command line after 19.3 had booted from the internal disk.
Troubleshoot to isolate the responsible component.. does the issue happen with kernel 4.15? which boot argument in compatibility mode makes a difference? Can you apply it post-install and install the NVIDIA drivers?
