On mu Ubuntu 12.04 setups my tmux clipboard copy and paste commands are setup as follows:
set -g prefix M-a unbind C-b bind C-c run "tmux save-buffer - | xclip -i -sel clipboard" bind C-v run "tmux set-buffer \"$(xclip -o -sel clipboard)\"; tmux paste-buffer"
This worked great for the longest time up until a month or so ago, when I suspect some configuration change or package change was made that broke the above. In GNOME terminal, pasting still works fine with both prefix+ctrl-v and ctrl-shift-v.
xclip copy command no longer works no matter what I do, and I have tried removing the custom prefix binding above, using
-select instead of
-sel, not using
clipboard etc. This is pretty much a show stopper for a GVim user like me, since I don't even have the GNOME terminal workaround of ctrl-shift-c with tmux taking over the shell. I go into copy mode, select text with space+movement, and when I execute prefix+ctrl-c absolutely nothing happens. Before this broke, tmux would display a confirmation message in the notification section at the bottom.
Does anybody have suggestions as far as how one might debug this? This is a pretty big productivity hit. I can probably use the temporary file workaround trick for now, but it'd be great to know just what happened to
