Installed Ubuntu Mate recently on my gaming rig. Must say I’m impressed, every game works flawlessly and performance is amazing. I also use this rig to watch some videos.
I have a vanilla install with a few extra apps (chrome and steam)
I was experiencing some bad screen tearing issues in the desktop (while scrolling or moving around windows), playing videos(plex, youtube, netflix) and in games. I fixed it by adding to the xorg.conf, under the screen section the following:
Option "metamodes" "nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"
This took care of all screen tearing issues, but since then, every time I use the shutdown button, the desktop environment sort of crashes (all icons turns to red X) and eventually shutdowns, but only after several seconds (previously was instantaneous) like it is hitting a time out or something. This is a picture of the issue:

If I shutdown from the command line, there is no problem. I have an nvidia gtx980 with the propietary drives (355 using the official Ubuntu graphic drivers ppa)
I found the following errors in the xorg error log, but googling for that didn’t help much:

Most interesting seems the last line, about shutdown interface.
Any ideas?
