Today while I was trying to share some information with my advisor, I figured out that my print screen bottom does not work. I did not use it for a long time especially after our work stations were updated to LEAP 42.1 . After some search I found the solution. The reason is that in KDE, the “ksnapshot” has been replaced by the new application, “spectacle” at LEAP 42.1 . You may need to configure the keyboard shortcut.
Configure Desktop ==> Shortcuts ==> Custom Shortcuts
I hope this would be useful for you. 🙂
