severity 609916 important
thanks
Hi Ian
I agree with you that it may not be the best thing to change the
leds on the system. However I do not agree with you that a software
component should never change anything by mearly being installed.
If you follow that reasoning (for example) apache should never open
any network ports by default.
ledcontrol contains a daemon process to manage the leds. The default
is to start the daemon.
>From the documentation:
leddThe LED daemon. ledd must be running when the other programs
are used. On startup, it executes programs and/or scripts to
tell it how to set the LEDs. It is configured in ledd.conf.
What we can do to solve this issue is to change the default for ledd
so that it do not start by default. Most people do however expect daemons
to be started when installed.
The reason for your serious problem is obviously because you have a
broken keyboard. I do not expect normal software components to be able
to handle broken hardware.
I'm not sure this should be fixed, but I'm open for discussion. However
serious is a bit hard as it would remove the package from next release
and this have been the case for all releases with ledcontrol as far as
I can tell. So it is not a new problem.
Due to this reasoning I'm lowering the severity of this bug with a hope
that we can discuss it.
Best regards,

PS. The package is up for adoption. Anyone is free to take the package
over, and if that person have a different opinion I will not object.
