I am using gdm (Gnome Display Manager) and gnome3 (regular, not classic) on Ubuntu 16.04.

After switching from Unity, I am not able to see any window decorations on all windows.

I cannot resize the windows correctly and I have seen no option on how to turn this on in the Compiz Settings Manager and in the Gnome Tweak Tool.

Here's a screenshot of the issue, as you can see there is no window border.

  • Is your system fully updated? –  Jan 28 '17 at 17:39
  • @CelticWarrior what versions of things should be I looking for? –  Jan 28 '17 at 19:20
  • Just run `sudo apt update && sudo apt full-upgrade` –  Jan 28 '17 at 19:27
  • I just did an update, what would the full-upgrade do if I'm 16.04 LTS and have upgraded gnome3 to the latest version? –  Jan 28 '17 at 19:28
  • Whenever installing software, particularly from third party PPAs and especially DEs regardless of where they come from, you should have the system fully updated. `apt upgrade` usually does that, `apt full-upgrade` also installs pending packages and is often used by the Update tool (use the GUI if you want, the end result is the same, cli is faster). –  Jan 28 '17 at 19:32
  • it didn't do anything, my system is fully upgraded. thanks though. –  Jan 28 '17 at 19:43

  • that fixed the window decorations, the cursor and icons still appear small in some apps (maybe I have to restart?) –  May 20 '17 at 14:17
