Testing 18.04: can't log in after closing laptop lid

[Willem Hobers]

Hi all,

Using 18.04 on a Lenovo laptop.

I've set the system to turn off the screen when I close the laptop lid.
If I then open the laptop again I am presented with the log in screen.
When I log in, I am -after some toing en froing- again presented with the
login screen.
When I log in for the second time I am presented with a black screen and
there is nothing I can do but to turn the laptop off, and then to reboot.

How do I investigate this issue? Which logs should I have a look at? Where
to report this?

Please advise,

Willem

I'm reporting a similar problem using Suspend on a desktop running
Xubuntu Core 18.04 (20 March build plus daily updates)
Reboot restores original performance.

Nvidia graphics card (but currently using nouveau driver)
