Can't paste in gnome-terminal from Keepas2 running via mono

Solution 1:

I found the solution!

I can confirm this works on OpenSUSE and Arch Linux. I hope this works on other distro's too. I tried everything in this question How can I merge the gnome clipboard and the X selection? but nothing helped. I found this bug at launchpad which worked: https://bugs.launchpad.net/ubuntu/+source/keepass2/+bug/1010289 .

Solution: Install both xdotool and xsel, and restart gnome-terminal and keepass2.

I tested this on gnome-terminal, terminator and konsole.

EDIT: this solution works, however not for some Java based applications. (PHPStorm and other Jetbrains software) I solved this: - install parcellite - start it - right click on the tray icon and choose preferences - make sure Use Copy (Ctrl+C), Use Primary and Synchronise clipboards are enabled.

EDIT2: There is a better solution for the Java problem (thanks @colan), a patch has been merged into xsel but this hasn't been released (see: https://github.com/kfish/xsel/pull/6), but compiling from source is very easy:

1. first remove xsel using your package manager
2. clone the repo: git clone https://github.com/kfish/xsel
3. cd xsel
4. touch README (looks like the autogen script needs a README file, but can't found it)
5. ./autogen.sh
6. make
7. sudo make install

You can manually test it: echo "test" | xsel -i -b.

This will install xsel into /usr/loca/bin/. Note that version 1.2.0 of xsel is not the correct version, this was released 9 years ago and doesn't include the patch! On arch linux you can use xsel-git from the AUR https://aur.archlinux.org/packages/xsel-git/.
