Please: 1. Try to explain the problem in different words. 2. Uninstall all of these extensions: '[email protected]', '[email protected]', '[email protected]', '[email protected]', 'cpufreq@konkor', 'temperature@xtranophilist', 'system- [email protected]', 'TilixDropdown@[email protected]' then log in again and tell us if the problem still happens. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1928556 Title: When opened modal password input window power off button don't work Status in gnome-shell package in Ubuntu: Incomplete Bug description: I opened wifi connect dialog.
