Copying issue on linux

[Dagur]

Describe the bug
If I copy something in lazygit and paste it back in, I don't get the same string. Possibly only on Linux.

To Reproduce
Steps to reproduce the behavior:

1. Highlight a branch and copy its name with Ctrl-o
2. Highlight the main branch and press n to create a new branch
3. Try to paste the old branch name in the input box with Shift-Insert or middle-mouse click.

Expected behavior
The branch name that I copied should appear.

Actual behavior
I either get no text or something I copied earlier from elsewhere.

Workaround
I paste the branch name into gedit or some other text editor, copy it there and now I can paste into lazygit.

I'm not familiar with clipboard handling on Linux. There's some code that auto-detects the right commands based on a heuristic, and it sounds to me like this heuristic gets it wrong for your system for some reason. Please see if this section from the docs helps.
