I have this problem too, but not at every startup. It only happens sometimes. Also gnome-tweak-tool often crashes (similar to comment #15 ) and sometimes screen locking behaves weird (see attachment) - I can take a screenshot and it lands in my Images folder, but I can't alt-tab, or anything like this. I have to ctrl+alt+F6, login and run
DISPLAY=:0 gnome-shell --replace , but sometimes even this doesn't work.

I'll disable it and try other workarounds mentioned here. ** Attachment added: "Weird lock screen glitch" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1236749/+attachment/3923306/+files/Zrzut%20ekranu%20z%202013-11-28%2017%3A11%3A35.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1236749 Title: Gnome shell extensions disabled at every startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1236749/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
