Linux Voice: an awesome Linux magazine

April 10, 2015 Leave a comment

Linux Voice is an independent GNU/Linux and Free Software magazine from the most experienced journalists in the business. It’s different in three key ways:

  • 50% of our profits go back to the Free Software community, developers and events
  • Our content is freely licensed (CC-BY-SA) after nine months, for the community to share
  • We are making this magazine for Linux users, and not to satisfy shareholders or middle managers” (source)

What’s so cool about it? Every issues is released for free after 9 months! I created a gist for the freely available issues: If I don’t forget about it, I will try to keep it updated. The latest issue (issue #5) just came out yesterday, April 9.

disable “quiet splash” during boot

March 12, 2015 Leave a comment

Today my laptop froze and I switched it off with the power button. Well, after this it didn’t boot :( The splash screen appeared, but after a few seconds the HDD led stopped blinking and nothing happened. What’s wrong?

As long as you have that stupid splash screen, you won’t see what the problem is. Upon boot you can switch it off temporarily. In the GRUB menu choose “Advanced options”, then at the bottom you will see thet with “e” you can edit the commands (press “e”). Find the line that starts with “linux” and delete “quiet splash” at the end of its line. With CTRL-X you can continue the boot. (See this thread for screenshots.) Now you will see what the problem is.

In my case the root partition got corrupted a bit and had to run “fsck” on it manually. But I could only see this problem when the splash screen was deactivated. Fortunately it was nothing serious and my system is back to normal.

After this the first thing was to edit “/etc/default/grub” and remove “quiet splash” permanently (don’t forget to run update-grub after editing this file).
