Overnight, my left side monitor doesn't display. It seems to be connected and registered with the display manager but no signal getting through.
I'm using lightdm as display manager now and have just upgraded to 18.10 from 18.04 hoping that would help. Still the same issue. I have tried the changing resolution but it either makes no difference of it says not found:

Any ideas anyone?

how did you perform the upgrade from 18.04 to 18.10? did you at any point uninstall/reinstall graphics driver? what graphics card do you have? are you using xorg or wayland, (if you don't know it's wayland)?
– tatsu
Mar 28 at 12:40
thanks for reply! Graphics Card is: VGA compatible controller: Intel Corporation HD Graphics 630 (rev 04). I upgraded with standard upgrade-distro command. This has happened before several months ago but it sorted itself out some how and happen again now BEFORE upgrading, but the problem persists. Arandr does detect the monitor and have it as active, yet no signal is getting to the monitor. It's X11 ($ loginctl show-session c2 -p Type >>> Type=x11 )

Mar 28 at 20:02
no problem, you didn't answer my question about uninstalling graphics drivers. if you have intel graphics driver installed before upgrade you need to uninstall it and reinstall it. do you have this ppa:ppa:oibaf/graphics-driversin your "Software and Sources" sources tab?

I have never manually installed a GC driver on this pc. I don't seem to have anything like that on my software / others -list of ppa and standard ubuntu repos
– Simon P
Mar 28 at 20:40
would you mind doing this then :sudo add-apt-repository ppa:oibaf/graphics-drivers -y && sudo apt update && sudo apt full-upgrade -y? then go into additional drivers see if it proposes anything, if yes, install it, and in both cases reboot.
