No display after boot, following recent updates

Since installing some regular software updates at the end of July, my PC now shows nothing but a blank screen after booting. The GRUB menu displays, but as soon as the OS begins to boot, the display goes entirely blank.

The PC is running mint 19.1. The screen is a TV, connected by HDMI. I tried using several older kernels, and still got the blank screen. I created a live USB with 19.2, and the display works.

I posted this question before under "installation and boot", but although it occurs when booting, the OS seems to work fine. I can SSH in, and everything looks normal. It's just that there is no display.

This is the output from inxi -Fxz, when booted into one of the older kernels:

Would anybody know what has caused this and how to fix it? Thanks

The info in your previous post in the Installation & Boot forum suggests there was a previous Timeshift restore point created. You can access this by using the Live USB. Use the one for Mint 19.1.

Unfortunately, the only system restore point that seems to have been created was after the upgrades which broke the display.

Nobody has a guess as to which package might have caused this? Or how to identify the problem?

Did you upgrade from Mint 18.2, because the inxi output lists the 4.8.0-53 kernel, which comes with that version of Mint?

When you get the black screen after the grub menu, try to enter virtual console tty1 by pressing, Ctrl+Alt+F1. Use this command to remove the monitors.xml file, if it exists. It’s not needed: sudo rm ~/.config/monitors.xml

Then use this command to upload the Xorg.0.log file to pastebin:
cat /var/log/Xorg.0.log | nc 9999

Post the URL link that displays in the Terminal window.

Then type reboot
