#1664 Cannot Copy/Paste in Linux
When I attempt to copy from KeePass2, the KeePass window loses focus and then becomes unresponsive and nothing is copied to the clipboard.
It appears that xsel locks up:
ps x | grep xsel
19475 tty2 S+ 0:00 /usr/bin/xsel --input --clipboard
If I kill the xsel process, KeePass resumes working, and begins the copy countdown timer. But still nothing is copied to the clipboard.
Uninstalling xsel makes the lock-up issue go away, but still nothing is copied to the clipboard.
Steps to reproduce:
1) Launch KeePass2
2) Click on an entry in the database
3) Type CTRL-C (or right-click -> 'Copy Password')
Excpected Results:
Password copied to clipboard
Actual Results:
KeePass locks up; no password copied
Details of my system:
Debian Linux - Buster (testing)
GNOME 3.26.0 (wayland)

Linux daniellenovo 4.12.0-2-amd64 #1 SMP Debian 4.12.13-1 (2017-09-19) x86_64 GNU/Linuxxsel --version

KeePass 2.36

A side note: earlier, when I uninstalled and later re-installed xsel, KeePass started working again. But it has since stopped working again.. so the issue may be intermittent.
Do you have xdotool installed as well? It is recommended for clipboard operations.
cheers, Paul
yes
I don't have any other suggestions.

This also affects me. I checked for hung xsel processes and found 4 after repeated attempts to copy from keepass2. Once I killed all of them and restarted keepass2, it worked, but I think I will have to do this every time keepass2 starts. Perhaps it is related to starting keepass2 on login?
Edited to add version info:

I continue to have this issue. Daniel, have you found a workaround? I reinstalled xdotool and xsel, but still have the issue. I wonder if these X tools are irrelevant now on Wayland.
The only thing that I've seen that might be relevant is https://github.com/rockihack/keepassx/blob/wayland-autotype/wayland.txt However, I have no idea how to implement this in KeePass - I'm not a coder.
It looks like KeePass will need to redirect input to uinput in order to work with Wayland. Because Wayland is simpler and designed to remove insecure processes (and is still relatively new), it is missing support for many things like middle-click text selection, or sharing clipboard easily between X and Wayland apps.
Currently I'm struggling with this issue on Fedora 29

I also can reproduce this lock-up without Wayland, solely on X.
I'd like to help with some debug logs; feel free to ask away if you need anything.
