Yes--I had to do some downgrades before I could upgrade to GnomeShell3, then re-upgrade after..all in all a "bit" of fun. It's all in flux right now & I expect a fair amount of breakage before it settles. Very good time to be current in CLI---it is needed
Maybe you wouldn't mind chiming in on this. Did you have a working mintmenu that you could access either through search or manually starting it or from a launcher shortcut you created before last weekend? And, if so, is it still working for you now? After one of the batches of updates, I believe on the morning of 4/12, my mintmenu stopped working - gives me a list of error messages in a popup window when I try to start it and, in fact, any older menu apps, i.e. Debian menu, main menu, etc. don't work now. Also, the menu applets from the awn dock now just crash at even trying to place them on the dock. Just curious if anyone else using Gnome 3/Gnome-shell was having the same issue. It appeared that some updates came through for different mint items over the weekend and also quite a few gnome 3 related items. I think it has something to do with the old gconf2 settings or something not being carried over to the new system, but I don't really know. I just reinstalled mint menu after completely removing it, I even searched for everything with mintmenu in the name and manually deleted it all before reinstalling mintmenu to come to the same results. I'm going to try to switch to fallback mode to see if it works there and let you all know what I find out. Definitely something the mint guys will want to take care of even if they never plan on supporting gnome-shell.
UPDATE: No difference with the above items in Gnome 3 fallback mode. Funny that the Gnome 3 menus work fine. So it's definitely some change that occurred this weekend that relates to how Gnome 3 is storing it's settings or something or maybe the menuing system.
