upgrade 16.04 > 16.04.1 = unable to move windows (even though move windows is checked in ccsm) and other gui issues

Question

Very new ubuntu user here.

I just updated ubuntu (running on virtualbox on windows) from 16.04 to 16.04.1.

When I rebooted my vm - all of the menus, panels, minimise/maximise/close elements were not visible. I have since managed to get the menus to appear as per screenshot below. I am able to right-click and open a terminal session and run programs (as per pgadmin3 running on the right-hand side of the desktop). If I right-click and open an additional terminal session, it is superimposed on the first, and I cannot alt-tab or alt-~ to any other terminal session.

In addition, I am unable to move windows, yet move windows is checked in ccsm.

I have tried the top-rated answers for the following questions without success:

• No panels or menus after upgrading to 14.04
• Ubuntu 16.04 no menu bar or launcher - help!
• Close/minimize/maximize button not appearing
• How can I always show the close, minimise & maximise buttons into their own windows?
• Ubuntu 12.04 Missing Close, Minimize and Maximize Button after Update and Upgrade
• Unity missing? Can't see top or side panels
• Application's menu missing from menu bar
• Unity doesn't load, no Launcher, no Dash appears
• Unity Launcher and Top Panel disappeared in 14.04

Any help would be really appreciated!

Answer 1

You need to disable the ccsm "window decoration" as it conflicts with the newest unity plugin.

Also, you need to enable the unity plugin in ccsm.

When using unity, all you need to do is click and drag down from the top panel to grab a window to move it.

I have found that alt button1 is a good option for the move plugin that works. Just press alt and hold down left click to move a window.

Answer 2

Enabling Place Windows plugin on CompizConfig Settings Manager did a trick for me.

BTW. I also have enabled Move Window and disabled Workarounds

And thank you for remebering abount Alt + Left Mouse for move the window!

Answer 3

I ran into the same problem yesterday after updating. I haven't been able to fix it, but I figured out a way to avoid it, by using i3 as my GUI instead of the the one that comes standard with Ubuntu. https://i3wm.org/docs/repositories.html

Answer 4

Uninformed Ubuntu user. The behaviour of Gnome windows changed after I messed up with the BIOS, setting up for UEFI and back for non-UEFI BIOS.

As a result, all new windows from Gnome opened too towards the left and too towards the top. And I could only move/resize windows with the ALT+move trick (for the first time; after I ALT+moved the window, the behavior was normal). Windows opening in LibreOfficee (for example) behaved correctly.

After messing up for a while trying the recipes from this thread (without success) and others, I found the solution by opening CCSM from terminal -> Window Management -> Place windows -> General (tab) > uncheck "Workarounds" (+ all other suggestions from this thread) Hope this can be helpful
