Thanks gnuite. Works fine.

I can now set my timeouts to 60 Min when using my USB keyboard.

Now I am thinking about how to detect me connecting my USB keyboard and changing the settings automatically.

I can grep in /proc/bus/usb/devices to check if the keyboard is there, but with no cron, I can't do this periodically. That seems kinda awkward anyway.

hotplug may be able to help, but we don't have that either.

Any ideas?
