Brother MFC-7820N under Kubuntu 14.10 Utopic

  • install Brother driver brscan2 (including adding the line brother2 to /etc/sane.d/dll.conf, see this guide)
  • brsaneconfig2 -q worked but scanimage -L showed “no sane device found”
  • Brother FAQ tells you to copy libs from /usr/lib64/sane to /usr/lib/sane but sane is looking in /usr/lib/x86_64-linux-gnu/sane
  • Finally scanimage -L shows device `brother2:net1;dev0′ is a Brother MFC-7820N SCANNER
  • Hint: for debugging of scanimage, use SANE_DEBUG_DLL=3 scanimage -L

Set up Brother MFC-7820N as network scanner under Kubuntu

I’ve set up my Brother MFC-7820N ages ago to print and scan over the network from Kubuntu. Once in a while the router decides to change the IPs of my network devices. So just as a note to myself, here’s how to set up the scanner again:

  • check the setup: brsaneconfig2 -q
  • delete the old entry: brsaneconfig2 -r MFC-7820N
  • determine new IP (as an exercise for the reader)
  • set up new entry: brsaneconfig2 -a name=MFC-7820N model=MFC-7820N ip=

Fix Non-persistent Window Size for Thunderbird

For a while (it might have started in the days of Intrepid/Kubuntu 8.10) my Thunderbird window never remembered its geometry between restarts. When starting TB, I always got a small window which I then had to resize to the desired size. No changes to prefs.js seemed to make a difference. Today, I came across a post which pointed me into the right direction. On Jaunty (Kubuntu 9.04), I had to do the following: Open System Settings, click on Window Behaviour in the section Look & Feel.
