I have 17.10, been using
gnome-flashback for quite a long time, since 16.04 and kept upgrading.
After installing latest updates, I can't make gnome-flashback to appear. In the login screen, I can choose Gnome Flashback - Metacity or Gnome Flashback - Compiz, but both, when chosen, end up displaying the new layout with "Activities" and the large icons panel on the left.
I have tried reinstalling
sudo apt-cache depends gnome-flashback | \ grep '[ |]Depends: [^<]' | cut -d: -f2 | tr -d ' ' | \ xargs sudo apt-get --reinstall install -y
which finished, but after restart, I still end up in that weird layout.
Also, when I lock the screen, it behaves like something was pressing enter every ~500ms, so it's not possible to enter the password.
What happened? Is that a bug? Is Gnome Flashback supposed to work? What should I try to get it back? Thanks!
Update: After reinstallation of
gnome-flashback, some GTK apps wouldn't start, e.g. Synaptic said:
$ sudo synaptic Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused (synaptic:3867): Gtk-WARNING **: cannot open display: :0
I was able to solve it as per this. I think I had this issue after upgrading to 17.10. Not sure if it is related to my issue above.
