I have recently switched to the Colemak keyboard layout and the Ctrl+Alt+L key combination no longer locks the screen. I have checked the keyboard shortcuts menu and it is still set correctly.
I have also tried locking the screen using this combination in Dvorak, and the problem persists. Changing back to Qwerty restores the functionality, and although switching back is simple to do (another shortcut) it would be nice to be able to do this with Colemak.
There are other shortcuts that have also stopped working, so the problem is not specific to the lock shortcut:
- Ctrl+D in terminal doesn't close the terminal.
- My custom shortcut, Super+T won't open the terminal.
Running Ubuntu 10.04.

Turns out this is a known bug: Apply keyboard layout for control key combinations
