Ubuntu – can't write capital z
I am using Ubuntu 10.04, and from the moment I installed it, I couldn't type capital z, all other shift+letter are working fine, but when it comes to z, it pops up a message with the title “Metacity” saying:
“There was an error running System Monitor:
Failed to execute child process “System” (No such file or directory)”
How can I fix it?
(And yes, I can use Caps-lock and z, but I wonder what is causing the problem)
