navigation shortcuts do not work aver xorg update

[Patrick Koppenburg]

Since this morning keyboard shortcuts related to window navigation do not work any longer. If I try to move a terminal window to a workspace left short-ctrl-alt-left is ignored but shown in the terminal as "8A". Also, moving to another workspace does not work. If I click on an icon in the unity bar of a window that is open in the present workspace, it goes to it. If it's in another workspace, the click is ignored. The only thing that allows me to navigate workspaces is to use the workspace switcher.

This morning there was a (maybe unrelated) update of xorg

Start-Date: 2017-10-18 09:08:48
Commandline: aptdaemon role='role-commit-packages' sender=':1.203'
Upgrade: xserver-common:amd64 (2:1.18.4-0ubuntu0.6, 2:1.18.4-0ubuntu0.7), xserver-xorg-core:amd64 (2:1.18.4-0ubuntu0.6, 2:1.18.4-0ubuntu0.7), google-chrome-stable:amd64 (61.0.3163.100-1, 62.0.3202.62-1), dkms:amd64 (2.2.0.3-2ubuntu11.3, 2.2.0.3-2ubuntu11.5)
End-Date: 2017-10-18 09:08:56

The problems started after I logged out and in after this change. I have a dell 15 XPS

Linux arvine 4.4.0-97-generic #120-Ubuntu SMP Tue Sep 19 17:28:18 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

What else can I do?

Activating Desktop wall in ccsm solves the issue.

I still think that a feature ceasing to work silently is a bug.
