gnome desktop crashes

After booting into the gnome desktop, a minute or so passes then the screen says “oops! Something went wrong” then it logs out. I log in again and all is alright. This happens every time I boot or reboot my computer.

This started after I installed kdegames.

Anyone know how to fix this?

That usually indicates a video problem. So do you have a NVIDIA card and how did you install the driver? If not what card what driver??
