Crashes when second monitor's resolution is changed

[sami1592]

So I have two displays, one is from my laptop(1366*768) and another external monitor(1920*1080)

- When I first installed Linux Mint 18.3 Cinnamon, the dual monitor setup worked fine(monitor extended with recommended resolution on each monitor)
- Then I installed some desktop environments to try them out
- Presumably that caused that the problem, for a while second monitor was not detected. Now it detects it but external monitor runs on a lower resolution. Whenever I try to change it the whole thing crashes.
- In guest session everything works fine.

OP here, for me the solution was this, I got it from the user Orcus in HexChat(a chat room for helping with issues)

- as "guest" does not show the issues - it's likely related to your users config

- In your home directory you could test if renaming ~/.config/dconf/user , logout & login. Try to change the resolution now.

- if this does not help you can go 1 step higher in hierarchy and rename ~/.config , logout & login. And test again

PS: prefer to rename the user -file and the .config-folder instead of deleting it as you could revert back that way
