Well, after an upgrade and reboot (including mutter 3.30.1-1), 'alt space' now works to bring up the m enu.
However, there is no 'Always on visible workspace' option. So I will close this bug as 'fix released' and I have opened bug 1797120. ** Changed in: mutter (Ubuntu) Status: New => Fix Released ** Changed in: mutter (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1795410 Title: cannot bring up window menu via keybinding (alt-space or otherwise) Status in mutter package in Ubuntu: Fix Released Bug description: I'm accustomed to hitting 'alt-space' to 'Activate the window menu' where there are options like 'Always on Top' or 'Always on visible workspace'. After an upgrade today I can no longer bring up that menu. Alt-space simply does nothing. Configuring the keyboard shortcut in gnome-control-center to another shortcut has no effect.
