Ubuntu – Ubuntu 18.04 opening system setting logs me out


I've recently installed Ubuntu 18.04 in a dual-boot configuration with Windows 10. I noticed today that, when trying to open system settings, Ubuntu seems to log me out to the lock screen. When I log back in, all previously-running applications are now closed. Very unsure what to do from here, any help much appreciated.

I had a look in /var/log/kern.log and noticed nouveau was crashing about the time I tried to open gnome-control-center.

So I installed the latest stable nvidia drivers (I'm using an nvidia graphics card), rebooted and now it works.
