You have been subscribed to a public bug: On Ubuntu 21.04,since around 01 July 2021, Alt-Tab works as usual for a while after logging in, but then stops entirely (that is, it does nothing; the switcher overlay fails to appear, and switching between windows does not work). I made _no_ configuration change, and Alt-Tab continues to be configured in the keyboard shortcuts settings as usual.
This has been described by other users here: https://askubuntu.com/questions/1349544/alttab-stops-working-after-a -while-in-ubuntu-21-04 There seems to be some possible connection to Thunderbird in particular, and the fact that in the left-hand-side launcher (?) / favourites of the Ubuntu desktop, the Thunderbird icon starts behaving strangely, e.g. does not show the open Thunderbird windows when clicking on it ... while other applications work. ** Affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment hirsute -- Window switching with Alt-Tab stops working after a while https://bugs.launchpad.net/bugs/1934527 You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
