Re: System no longer starts

Interestingly, lightdm did start up without issue. The login prompt looks a little different, but it starts the same Trinity desktop. I wasn't sure if a desktop environment and display manager were the same thing, so I read up on that a bit.

It's not ideal, but it's a help in one way because the original login screen didn't respect my monitor's scaling settings and could not be read from more than 6-8 inches away.

I'm going to report this back on the bug at Trinity. With only the login prompt UI changed, this should be an acceptable workaround for right now; but it's something I'd hope to see addressed.

Re: System no longer starts

If lightdm starts up fine and tdm doesn't, it's likely a tdm bug. We would assume some sort of tdm with systemd clash. Unfortunately we are not able to reproduce and investigate it at the moment, however we are going to check some more possibilities to reproduce that. Anyway, thanks for reporting.

Re: System no longer starts

I'm wondering if you could just do the "sudo dpkg-reconfigure tdm-trinity" to sort it out?

Yes, that fixed it!

Still no UHD scaling on that prompt, but everything works perfectly now!

Thanks!

Re: System no longer starts

I had a similar issue with my old Dell laptop and had to use a workaround to get it sorted, it went like this...

When you are booted to the console log in with your user credentials, if your system fails to get you to a console use the keys Ctrl+F1 to get you to a fresh one (you can use any F key F1 through to F7 but F7 is usually your desktop)
Then issue the following commands

sudo systemctl stop tdm.service

sudo X -configure

sudo mv xorg.conf.new /etc/X11/xorg.conf

sudo systemctl start tdm.service

This might work as it creates a fresh xorg.conf from the available hardware, hopefully it will help.

For reference the issue I had (after upgrading kernel) is in this post and the resolution is in this post

Same issue HP4540s and HP4740s. This helped.
