Usually when I needed to paste stuff from a text file into a GUI program (most commonly, the browser), I resorted to opening the text file in gedit and copying/pasting from there. Using the X clipboard by selecting text with the mouse kinda worked, but it’s subject to Vim’s visual representation of the text, which may include unwanted display-related breaks. So using gedit was the easiest, but also awfully kludgy solution.

I did some research and learned that vim does have direct access to the X clipboard. I tried the commands they mention (basically "+y to yank selected text, then I tried to paste in a GUI application; or "+p to paste from the current X clipboard). They didn’t work. My installed version of Vim in Ubuntu lacked the xterm_clipboard setting. I was in despair!

Then I came across this bug report in Launchpad. Upon reading it I realized that it was as simple as installing vim-gtk. I had never considered this, as it includes a graphical Vim version which I have absolutely no use for. However the bug report mentions that it also includes a text version of vim compiled with X clipboard support. So I installed, fired up Vim, and the feature works well!

I can now have a buffer with long lines, with :set wrap and :set linebreak, which would be afwul if I cut/pasted it with the mouse. I can select text using vim commands and just yank it into the + register, and it’s instantly available in the X clipboard. Bliss!
