Re: [Condor-users] KeyBoard Idle Time infinite

Hello everybody.

I just checked my Condor StartLog and to my surprise I get this message there which assumes infinite idle time for my mouse/keyboard stating: "2/11 07:36:56 Unable to calculate keyboard/mouse idle time due to them both being USB or not present, assuming infinite idle time for these devices."

Does anyone have any idea, why is it so? and how can I configure my condor to take in to account this measure,. I am sure the keyboard and mouse are present and yes they are connected through USB, so how do I make those changes to get such information. I mean I would like to know the information when are the users coming back to the machine, and "KeyboardIdle" will be the best ClassAd to give me such information. I have installed Condor v 6.8.6 on my 3 machines, with one being the Central Manager.

Condor does not know when there is activity on a USB connected keyboard because the Linux kernel will not tell it.

IIRC, you have a couple options. The most straight-forward is change the kernel via a small patch as discussed here:
Over time many folks have requested many times for this patch to be adopted into the mainline kernel, but so far it has not happened.

Another possibility is to use the condor_kbdd if you are always running an X server on your machine(s). The condor_kbdd monitors keyboard/mouse activity by asking the X server instead of the kernel, and it fowards along what it discovers to the condor_startd.

Anyone aware of any alternatives beyond the two above?
