Copy and paste problem in Eclipse under XFCE
At my student job we encountered the problem that within Eclipse, we use Galileo (3.5), copy and paste frequently failed. Sometimes it helped to hit Ctrl+C a couple of times but this was annoying and didn’t work reliable.
So I started to search the web for a more convenient solution. In the beginning I didn’t suspect our desktop XFCE but when I tried what is suggested here our issue seemed to be solved. The linked post advises to disable the autostart for the xfce4-settings-helper and stop running instances. After doing this, copy and paste in Eclipse immediately worked again. Repeatable. Without failure between two attempts.
