Just updated my Thinkpad T420 up to 18.10 with a fresh install (full wipe). This is a machine with Optimus and I did install prime-select, but only after I was having issues. Otherwise this is a plain system, updated to latest stable updates, with Chrome and Wine installed, but the issues i'm encountering are with nothing running.
The laptop suspends fine, goes fully to sleep with the suspend light on with the system. Upon opening the lid though, I see the monitor blink on for a second with the mouser cursor and then immediately shut off again, the backlight and all turning off.
Pressing ctrl-f1 and then ctrl-f8 shows the console login and then brings me back to the usual XFCE login screen where I can unlock, but without doing that I'm unable to see anything.

Typing my password into the blank screen brings me back to my desktop, so it seems like things in the background are working, but the graphics on the screen are not.
I also tried using prime-switch to test each setting (nvidia and intel) and the same effect happens with each.
I attempted the nouveau.modeset=0 and a couple other fixes in grub, but none of those seemed to have any effect.
The computer is running the latest BIOS afaik.
I haven't seen any bugreports dealing with 18.10 resume issues yet, at least of this type. Anyone else having problems?
Wondering what's the best way to figure out if this is the graphics driver, lightlocker, or something else so that I can open a bug report with the right package.
