What is the output of `gsettings get org.gnome.desktop.wm.keybindings panel-main-menu`?

[Norbert (nrbrtx)]

Bug exists in 15.10 alpha,

  gsettings get org.gnome.desktop.wm.keybindings panel-main-menu
  ['<Super>s']

why you changed traditional <Alt+F1> to ugly <Win+s> ? Where I can read about this change?

[Alberts Muktupāvels (muktupavels)]

Default is ['<Super>s', '<Alt>F1']. Maybe there is some script that changes it to only [<Super>s]?

[Norbert (nrbrtx)]

I get this bug in clean install of Ubuntu 15.10 beta2 with GNOME Flashback (Compiz) session.
`gsettings get org.gnome.desktop.wm.keybindings panel-main-menu` returns ['<Super>s'] here, but this shortcut zoomes out desktop and do not open menu.
I have this behavior even in guest session.

Please fix this bug before final release.

[Alberts Muktupāvels (muktupavels)]

In bug report you speak about metacity session, but now about compiz...

Can you show output of these two commands:
- grep -r "<Super>s" /usr/share/glib-2.0/schemas
- grep -r "<Alt>F1" /usr/share/glib-2.0/schemas

That might show why you have only <Super>s, if it is changed with .override file.

Last problem is that compiz plugin use same shortcut. First program that grabs that shortcut wins that is why it only zooms out your desktop and does not open menu. Only way to fix this is by changing shortcut in one place or other.

Bug exists in Ubuntu 15.10 final with GNOME Flashback (Compiz).

[Steve-a-reno (steve-demeo)]

Yes I have the same issue* using Ubuntu 15.10 Flashback (Compiz).
* The Alt-F1 key does not open the (Applications) main menu.

Your work-around (below) did fix the problem for me though: -

$ grep -r "'<Super>s'" /usr/share/glib-2.0/schemas

# backup this file
$ sudo cp /usr/share/glib-2.0/schemas/org.gnome.desktop.wm.keybindings.gschema.xml /usr/share/glib-2.0/schemas/org.gnome.desktop.wm.keybindings.gschema.old

# Edit this file to remove <Super>s keybinding.
sudo nano /usr/share/glib-2.0/schemas/org.gnome.desktop.wm.keybindings.gschema.xml

# The old file contains the line
$ grep "'<Alt>F1'" /usr/share/glib-2.0/schemas/org.gnome.desktop.wm.keybindings.gschema.old
<default><![CDATA[['<Super>s','<Alt>F1']]]></default>

# The new file contains the line
$ grep "'<Alt>F1'" /usr/share/glib-2.0/schemas/org.gnome.desktop.wm.keybindings.gschema.xml
<default><![CDATA[['<Alt>F1']]]></default>

# Once I logged out and logged back in again the Alt-F1 shortcut for (Applications) main menus now works again.

Bug exists in Ubuntu 16.04 with GNOME Flashback (Compiz).

[Norbert (nrbrtx)]

Bug exists in Ubuntu 16.10 with GNOME Flashback (Compiz).

[Alberts Muktupāvels (muktupavels)]

Is this still problem?

<Super>s has been reverted 2 years ago:
https://gitlab.gnome.org/GNOME/gsettings-desktop-schemas/commit/1a5e5a54b2a4b182d9a48c43678b054c3d081f5f

Also real problem here might be that compiz does not support multiple keybindings!? So it picked first keybinding, in this case <Super>s.

[Norbert (nrbrtx)]

Ubuntu 16.04 LTS is still affected.

But Ubuntu 18.04 LTS, 18.10, 19.04 are not affected.

[Dmitry Shachnev (mitya57)]

Sorry, we do not have time to support old LTS releases. And support for 16.04 universe packages ends in 2 months anyway.
