The dmesg file is empty

The dmesg file is empty, all it contains is:

(Nothing has-been logged yet.)

But in the terminal running dmesg if giving data.

I’m not 100% positive of this, but I don’t believe dmesg is an actual file to be displayed, but rather a command used to examine logged events. I’m not entirely certain why dmesg is listed in log file viewer

dmesg - print or control the kernel ring buffer copied from results on man dmesg

@pfeiffep is right. I think it’s a bug with the Log Viewer application since it’s showing the same message here.

Running dmesg in the terminal shows the entire log.
