Turning on /proc/sys/vm/block_dump to track something else, I noticed something is constantly being written to /var/run/atieventsd.Xauthority file.

Which has size 0, all the time.

And by "constantly written" I mean many inode writes per second.


I am not sure what the file is supposed to do, I did man atieventsd, and as far as I gather, it has something to do with reporting ati events to the system and exchanging permissions with the X subsystem (I got an ATI card, using "radeon" driver). But I don't know exactly what it does, and if this "avalanche" of writes to a 0 sized file is normal or not?
