Status in gnome-shell-extension-ubuntu-dock package in Ubuntu: New Bug description: No matter how I try to lock my screen (Super + L, Menu Item, or Time Out) the screen tries to lock, but freezes for a second, and resumes my running gnome session as it was. If I try again after that, my session freezes and has to be restarted. If my computer is left at the regular login screen with no user signed in, It will respect power settings, and turn the screen off after 10 minutes. The following is a dump of my Syslog at the time of crash. ------------------------------------------------------------------------------ gnome-shell[10234]: Extension "ubuntu-d...@ubuntu.com" had
