I have always used Ctrl+Alt+Shift+Left/Right to move windows from left to right monitors.

Installed Ubuntu 18.04 last week (fresh install) and it appears that this is not working anymore despite the fact I had configured them like this in the Keyboard settings.

I'm guessing these shortcuts are already in use somewhere, but I have no clue where...
They are not listed in the Keyboard settings though and it does not indicate any kind of conflict.

Anyone knows how I can get this the way I want it ?


Edit:
So to be perfectly clear. I've set Ctrl+Alt+Shift+Left/Right > keyboard...
But when hitting the shortcut keys, nothing happens.

  • I cleaned all bindings, to find them use dconf dump / | grep left, but Ctrl+Alt+Left/Right still aren't forwarded to apps. – Greg Dan May 7 '18 at 13:56
  • also check for <Primary> as key instead of <Ctrl>... also saw <Control> I believe – dgoosens May 7 '18 at 14:53

In 18.04, the default hotkeys for moving windows to another monitor are Shift + Super + Arrow. Each arrow will correspond to the location of the destination monitor relative to where the focused window is.

Also, are you saying that you do not see a list of hotkeys in Settings > Devices > Keyboard?
I assume you are using gnome-control-center.

  • I know about the default... BUT have been using Ctrl + Alt + Shift + Arrow for over 10 years and seems legitimate to be able to change these settings. Everything is fine in Settings > Devices > Keyboard... I've got my settings there... But the set shortcuts don't work – dgoosens May 7 '18 at 7:58

    I see. So the problem is that gnome-control-center is not honouring your changes to the default hotkeys. What is returned when you do "dconf read /org/gnome/desktop/wm/keybindings/move-to-monitor-left"? – hiigaran May 7 '18 at 8:14
  • Cheers... This pointed me on the right direction. – dgoosens May 7 '18 at 8:48

So thanks to @hiigaran, I checked out dconf

It appears my shortcutkeys were, as I supposed, in use already for move window to workspace left/right

These settings do not appear in the keyboard settings though as there are no lateral workspaces anymore !!
I guess it is a bug that these actions, although no longer available, still have an assigned shortcut key.

I simply removed the set shortcutkeys and everything it working again.

thanks @hiigaran for pointing me in the good direction !
