1- Clipboard: it seems that there is a specific clipboard for Emacs under Fedora/Gnome; I am unable to copy something from any other application and paste it in emacs. It is always the last thing copied/cut *in* emacs which is pasted in emacs
I get that *sometimes* too, but only when text in emacs is actively selected, but I use transient-mark-mode. If you use transient-mark-mode then try clicking in the emacs window to un-select whatever was selected, then you can select from another window.
