I'm running Vim 7.3 under Linux Mint 13 (using MATE) and I'm not able to save text to the system clipboard. I run Vim in the terminal and copy text from the terminal with CTRLINSERT. When I select text in Vim (either with the mouse or in visual mode), CTRLINSERT doesn't copy any text. In addition when I right-click, Copy is grayed out. Further, I can't write to the system buffer by yanking to the corresponding register using vim commands. However, I'm able to paste while in insert mode (using SHIFTINSERT or right-click paste). I'm also able to copy text directly from the terminal using the same technique, just not text from Vim.
Here is my current ~/.vimrc. The relevant part is most likely set clipboard=autoselect,unnamed,exclude:cons\|linux. If I put finish at the top of my ~/.vimrc, I have the same issue, so I think the line is wrong, but I've tried set clipboard=unnamed and had the same behavior.
Could there be another config file affecting Vim's behavior? How can I change my ~/.vimrc to allow me to copy text from Vim?
