After upgrading my working Kubuntu 14.04 LTS to 16.04 LTS a few days ago everything went fine.

But now I experienced that sometimes (I cannot even reproduce or find any rule for it) my clipboard hits and misses (e.g. sometimes I cannot paste values). Worst experience is with Intellij's PHPStorm. I am simply not able in 90% of the time (no matter what the source of the copy is) to paste any texts.

Only thing I found on the net was the tip to use the bundled OpenJDK which I do to my understanding:

PhpStorm 2016.3.2

Build #PS-163.10504.2, built on December 20, 2016

JRE: 1.8.0_112-release-408-b6 amd64

JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o

As I do not even know where to start to look out for this issue, can you please help me?

A couple of further info:

  1. I don't close any windows before I paste
  2. to my understanding I only have the Kubuntu 16.04 clipboard(s) installed
  3. there is no remote connection or anything involved
  4. anything happens locally with my standard user


  1. I checked as well any shortcut properties but nothing seems overwritten.
  2. 2nd Linux clipboard (mark a text and paste with middle mouse button) seems to work so far, issue seems to be with CTRL-C/V CTRL-SHIFT-C/V.

Only question here which comes close to mine but got no solution is: Kubuntu 15.04 Clipboard is behaving strangely

Please help, it's so annoying :-(


I had the same issue while KeePass2 running in mono.

This did trick for me:

sudo apt-get install xsel:i386

  • Indeed! This did it - thanks a lot. Quite sure this isn't a real solution but as long as it's working. – LBA Feb 2 '17 at 10:51
