The IntelliJ IDEA short-cut to reformat source code is Ctrl+Alt+L. This happens to lock the screen in KDE (Gnome too?). How can I disable this so IntelliJ receives the key sequence?

Under the K menu, go to the Control Center.
Regional & Accessibility | Keyboard Shortcuts | Shortcut Schemes tab, Global Shortcuts tab.
In the search box, type "lock", which should narrow the visible shortcuts and show the Ctrl+Alt+L one ("Lock Session").
Underneath, click None.
Click the Apply button.
On KDE Plasma 5 go to System Settings | Desktop Behaviour | Screen Locking
Here you will find a "Keyboard Shortcut" option. Change it to something else or set to none
I eventually found how to disable the lock screen key binding (Ctrl-Alt-L) in the System Setting app.
System Settings->"Keyboard Mouse->Keyboard Shortcuts
I had to choose the KDE component: Run Command Interface.
I'm running KDE on Fedora Core 9.
Also you can change it with the configuration file.
The following files store the keyboard shortcuts of KDE Plasma 5 and of some of its associated applications such as Konsole and KWrite.
~/.config/kdeglobals
~/.config/kglobalshortcutsrc
~/.config/khotkeysrc
~/.config/kwinrc
~/.config/plasma-org.kde.plasma.desktop-appletsrc
~/.local/share/kxmlgui5/katepart/katepart5ui.rc
~/.local/share/kxmlgui5/konsole/konsoleui.rc
~/.local/share/kxmlgui5/konsole/sessionui.rc
~/.local/share/kxmlgui5/kwrite/kwriteui.rc
Let me add descriptions for the files.
Standard Shortcuts (System Settings > Shortcuts) ~/.config/kdeglobals
Global Shortcuts (System Settings > Shortcuts) ~/.config/kglobalshortcutsrc
"Custom Shortcuts" (System Settings > Shortcuts) ~/.config/khotkeysrc
Konsole ~/.local/share/kxmlgui5/konsole/konsoleui.rc ~/.local/share/kxmlgui5/konsole/sessionui.rc
KWrite > Settings > Configure Shortcuts... > KWrite ~/.local/share/kxmlgui5/kwrite/kwriteui.rc
KWrite > Settings > Configure Shortcuts... > Kate Part ~/.local/share/kxmlgui5/katepart/katepart5ui.rc
For those who prefer visual answers, here's where this settings can be found
IMPORTANT Note that there are two values: Global and Global Alternative. I had to unbind the Global Alternative shortcut to resolve a problem with IntelliJ.
Ubuntu 20.04 + KDE plasma:
Use Global Shorcuts -> System Setting Module menu -> Lock session. Set to "Custom -> None"
