I've installed a weekly update from Ubuntu (Canonical) and when I reboot the System (and whenever I have to login to the PC), I face the following problems:

  • The Home Dash bottom is not working;
  • When the mouse pointer is over the Home Dash bottom or the Side Bar bottoms, they hide and come back again a few seconds after. The same with opened application windows (The Side Bar is configured as fixed on the left side of the Screen):
  • In the Menu Bar the Shutdown command doesn't work.

Errors reported by the system:

2018-01-13 17:01 2018-01-13 17:01 UTC Crash compiz-core

2018-01-12 12:01 2018-01-12 12:01 UTC Crash /usr/bin/compiz

Additional data:

  • System: ThinkPad T400
  • Ubuntu 16.04 LTS

Please, can you help to solve these problems? If you need any additional information or data, please, let me know. Thank you. Best regards,

Artur Campos
