[PROBLEM]
After changing the keyboard layout to german (on (K)Ubuntu Dapper/Edgy), I couldn't type the pipe character (AltGr + <) anymore.
[SOLUTION]
Change the keyboard layout to 105 keys instead of 104.
Example:
KDE: System / Regional settings / keyboard layout
Linux: Pipe "|" character not working on german la
Linux: Pipe "|" character not working on german la
