Everyone need's to use the dmesg command at one time or another, as it's the command that you type in a terminal to see if Linux has detected your hardware ok.
It's a good idea when submitting hardware bugs to Launchpad, to type dmesg into a terminal & to copy the output into your bug report. This would more than likely be the first thing that the dev's would ask you to do.
Linux Gazette has a very good article on dmesg here!

Hi there to every one, as I am genuinely eager of reading this
website’s post to be updated daily. It contains good material.
Hello! Quick question that’s totally off topic. Do you know how to make your site mobile friendly? My website looks weird when browsing from my apple iphone. I’m trying to find a template or plugin
that might be able to resolve this problem.
If you have any recommendations, please share.
Many thanks!
