I am new to Ubuntu. I just installed a fresh copy of 16.04 LTS on a Lenovo M8 3306 ThinkCentre desktop.

It is running great so far other than one weird problem in which I cannot find anyone else on google as having...

Whenever I click on anything to do with system settings, the screen goes black for ~10-60 seconds. Clicking the following things causes this weird problem:

  • "System Settings" icon in the menu bar
  • "System Settings" menu item in the top right power dropdown
  • "About This Computer" menu item in the top right power dropdown
  • "Change Desktop background" in the right-click on desktop dropdown

When the screen comes back on, the thing that I clicked will be open.

I have tried opening and closing various other programs and folders, but nothing else causes the screen to go black. It seems just anything that is somehow tied to system settings...

One more note: When I first turn on the machine and log in, when it gets to the desktop, it flickers, showing the desktop being a really small square and being the normal size, very rapidly. This stops after a few seconds.

Thanks for your help.
