[ACCEPTED]-Disable global Ctrl-Alt-L hotkey in KDE-kde
Under the K menu, go to the Control Center.
Regional 10 & Accessibility | Keyboard Shortcuts 9 | Shortcut Schemes tab, Global Shortcuts 8 tab.
In the search box, type "lock", which 7 should narrow the visible shortcuts and 6 show the Ctrl+Alt+L one ("Lock Session").
Underneath, click 5 None.
Click the Apply button.
On KDE Plasma 4 5 go to System Settings | Desktop Behaviour 3 | Screen Locking
Here you will find a "Keyboard 2 Shortcut" option. Change it to something 1 else or set to none
On Kubuntu 11.10 it's well hidden:
- Start System Settings
- Under Common Appearance and Behavior, select Shortcuts and Gestures.
- Select Global Keyboard Shortcuts in the left-hand panel.
- Select the KDE Component: Run Command Interface (important, otherwise you won't see the ctrl-alt-L mapping!)
- Select Lock Session
- Edit the setting, either choose a different mapping or 'none'.
I eventually found how to disable the lock 5 screen key binding (Ctrl-Alt-L) in the System Setting 4 app.
System Settings->"Keyboard Mouse->Keyboard 3 Shortcuts
I had to choose the KDE component: Run 2 Command Interface.
I'm running KDE on Fedora 1 Core 9.
For Linux Mint: System Settings -> Keyboard 2 -> Keyboard Shortcuts -> System -> Lock 1 screen
It's easy to disable all global keyboard 11 shortcuts in KDE for specific applications. I've 10 done it in KDE 4 and now I've done it in 9 KDE 5 again. So in KDE 5 right click on 8 your application's window title -> More 7 actions -> Special Window Settings (or Special 6 Application Settings) -> Appearance & Fixes 5 -> Ignore Global Shortcuts -> Force, Yes. It's 4 much easier than to look for each shortcut 3 one by one.
You can check such configurations 2 in System Settings -> Window Management 1 -> Window Rules.
Instead of disabling anything, you can also 5 use ctrl+meta+alt+l in most applications where this 4 problem exists. KDE knows the meta key (aka 3 the 'windows key'), but the applications 2 seem to ignore it and consider it to be 1 just ctrl+alt+l.
I know, old question, but I didn't easily 3 find a decent answer. If anybody is wondering 2 how to disable it on Ubuntu (while the Windows_key + L shortcut 1 will still work):
Settings -> Keyboard -> Shortcuts tab -> System -> select Lock screen and press backspace to clear it.
For KDE Plasma 5
1 - click on K menu, type keyboard, choose 2
Global Keyboard shortcuts
2 - Choose the
KDE Session Manager in KDE component , at
Lock Session, do what you want, disable 1 the shortcut or choose another!
For Ubuntu 16.04
System settings -> Keyboard -> Shortcut -> System -> LockScreen -> click-it and make changes
I changed my to ctrl+alt+H from 2 ctrl+atl+L
Here is the Screen shot which tells where 1 the above instructions will lead you to. Keyboard -> shortcuts
Another option is to change the Idea keymap 3 to use Default for KDE. You can go to File -> settings -> keymap and 2 then select the Default for KDE option from the drop down 1
Also you can change it with the configuration 11 file.
The following files store the keyboard 10 shortcuts of KDE Plasma 5 and of some of 9 its associated applications such as Konsole 8 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 7 files.
Standard Shortcuts (System Settings 6 > Shortcuts) ~/.config/kdeglobals
Global 5 Shortcuts (System Settings > Shortcuts) ~/.config/kglobalshortcutsrc
"Custom 4 Shortcuts" (System Settings > Shortcuts) ~/.config/khotkeysrc
Konsole ~/.local/share/kxmlgui5/konsole/konsoleui.rc ~/.local/share/kxmlgui5/konsole/sessionui.rc
KWrite 3 > Settings > Configure Shortcuts... > KWrite ~/.local/share/kxmlgui5/kwrite/kwriteui.rc
KWrite 2 > Settings > Configure Shortcuts... > Kate 1 Part ~/.local/share/kxmlgui5/katepart/katepart5ui.rc
For those who prefer visual answers, here's 4 where this settings can be found
IMPORTANT Note that 3 there are two values: Global and Global Alternative. I had to unbind 2 the Global Alternative shortcut to resolve a problem with 1 IntelliJ.
