New laptop: Dell Latitude 5480

Finally I am replacing the HP-Compaq TC-4400 (named Alice) I've been using since May 2008. Yes, for almost 10 years now. That is the notebook I started this blog for, so it's the end of an era for me.

I had to make plenty of compromises when choosing the replacement, but hey, it's new, it's fast, it's strong, it's even lighter a bit, and has better screen resolution. On the downside, it's bigger, it is not a tablet pc, and the keyboard is not exactly to my liking. Lucky me, the keys can be remapped.

The blog will be continued under the name Alice@Ubuntu even though I'll stop using the machine that gave the blog it's name. The content slowly shifted from machine specific configuration to more general topics throughout the years anyway.

How to completely remove Plex Media Server?

Source: https://support.plex.tv/hc/en-us/articles/201941078-Uninstall-Plex-Media-Server

  1. Shut down Plex Media Server
    service plexmediaserver stop
  2. Remove the installed package
    dpkg -r plexmediaserver
  3. Remove the library directory of plex
    rm -R /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/
But then, when I wanted to reinstall it, I ran into some errors, and the solution was to make sure that the /var/lib/plexmediaserver folder exists and the plex:plex user/group has owner access to it:
sudo mkdir /var/lib/plexmediaserver
sudo addgroup plex
sudo adduser plex plex
sudo chown plex:plex /var/lib/plexmediaserver

Scanimage produces unreadable lineart image with default settings

Compared to Ubuntu 12.04 and the default settings for Canon LiDE 210 flatbed scanner changed in Ubuntu 16.04.

The default result of a Lineart scan was unacceptable (unreadable).
It turned out, that --resolution was 75, and --disable-dynamic-lineart was no.
Setting options '--disable-dynamic-lineart=yes --resolution 300' for '--mode Lineart' solved the problem.
