I have a weird effect in one workstation: suddenly, the system does not allow me to copy text from a terminal to paste it somewhere else by simpling selecting it.

I can still paste into the terminal the text that I select in other windows. The problem is restricted to copying by selection from the terminal.

Also, I am aware of the ctrl+shift+v ctrl+shift+c key shortcuts. They do work fine, and so does copying and pasting with right clicks of the mouse after selecting text and then clicking "Copy" or "Paste" in the menu. However, I want to recover the misteriously gone ability of copying text from the terminal by selecting it...

Thanks for any suggestions!

This happened to me with Konsole as well.

Investigation of /var/log/syslog showed the following message each time I tried to copy: "QXcbClipboard::setMimeData: Cannot set X11 selection owner"

Following up on that message, it seems the issue was reported/fixed by: https://bugreports.qt.io/browse/QTBUG-65145
https://codereview.qt-project.org/c/qt/qtbase/+/254187

That issue matched my case, as my system had been up for 50 days before the issue started !

Looking at changelogs, that fix appears to be included in the 5.12.6 QT release.

Ubuntu 20.04.2 appears that it includes 5.12.8 currently, so should include the fix.

This might be a stretch but I have experienced something like this on my work laptop before. It tends to happen when I have many applications up and stacked on top of each other in the same window my terminal is. Even though the text is getting highlighted in the terminal, the click board doesn't end up with anything in it kinda like if one of the other windows was mysteriously between your mouse and the terminal window. What made it work for me is minimizing all the applications at once by doing the mouse shake. Sorry about the not so scientific answer.

Its now 2021 and this Konsole bug still exists, I'm on Debian 10, Konsole 18.04.0 build against KDE 5.54.0, Qt 5.11.3 + xcb.

You can temporarily work around it by giving your profile a new name, delete all other profiles and re-select 'Switch Profile' in the Konsole context menu, then select your newly saved profile.

However, it randomly comes back, also I have seen that it randomly creates new profiles (Profile 1, Profile 2, Profile 3)

From what I have observed, as long as you have 'Default Profile' as the name when you open Settings-> Edit Current Profile it doesn't persist options randomly.

go to terminal settings and create new profile and try selecting text in it maybe the profile did a setting that you don't know

or try changing your shell sometimes the problem is in the shell

sudo apt update
sudo apt install -y zsh
sudo apt install -y fish
sudo chsh
# 'Write shell Name Here'

Perform these commands to change your shell
