Lightdm, X.Org X Server terminates randomly,

Hi list members,

the lightdm's log output suggests to consult the The X.Org Foundation support. I guess, posting to this list would be appropriate?

I'm running an up to date Linux Mint which comes with

GFX card is a GeForce GTX 1050 Ti, Xorg.0.log attached.
Is this the right place and/or information to get an idea, what is wrong with this thing?


Thanks, Martin
