Only after disaster can we be resurrected

6 May 2008 21:50

I leave my main desktop logged in for months a time; as demonstrated by my previous bug with the keyboard transition for xorg.

The screen is setup to lock after 5 minutes of idle, so there's no real security issue, and it is extremely convenient.

Every few weeks though my desktop gets into a funny state where no new windows may be opened.. Existing applications continue running without any problems, but no new windows/shells/whatever may be opened.

Tonight it happened again.

And the lightbulb went on in my head: My flat uses CFEngine to manage itself. (Two physical servers here, with 5-10 Xen guests, and a number of remote servers.)

One of the things that CFengine is configued to do is to tidy directories of files which are older than 30 days. Including /tmp.

So that explains that.

Every month the magic cookie in $TMP would be nuked, and X would disallow new connections.

I guess the next time this happens I should look at using Xauth to fix the issue, but generally I just logout, make coffee, smoke a cigarette, and login again.

In conclusion: I'm a stupid-head.
