Connect to a NAS in Ubuntu Studio 20.10

I had to do the following to connect to a D-Link DNS320L network drive after an update to Ubuntu Studio 20.10 (prior to the update the drive was discovered and mounted automatically in Dolphin).

  • Add this to the [global] section in /etc/samba/smb.conf:
client min protocol = NT1
  • Add a vers=1.0 option to fstab, so the entry in /etc/fstab is:
// /mnt/raid-lounge cifs vers=1.0,guest,uid=1000,iocharset=utf8 0 0

Midi with Ardour on Linux

Here’s how to get Ardour set up so that the DAW can control a MIDI synthesizer. I’m using Ubuntu Studio, Ubuntu 20.04.1 LTS, Ardour 5.12.0.

  • Start Jack (I use QjackCtl).
  • In a terminal, type

a2jmidid -j default

a2jmidid is a bridge between the ALSA MIDI system and JACK.

  • Start Qsynth (a front-end to the fluidsynth MIDI synthesizer) and make sure a soundfont is loaded.
  • In the QjackCtl MIDI connections tab, connect the Output Port ‘midi_out’ of the MIDI track in Ardour to the Input Port a2j ‘FLUID Synth’.
  • In QjackCtl Audio tab, make sure that the qsynth left and right channels are connected either to a system audio output (for listening) or to an Ardour audio track (for recording).

Installing Scilab on Ubuntu 20.04 LTS

The default install of Scilab doesn’t work on Ubuntu 20.04. I downloaded Scilab 6.1.0 from the Scilcab website. When executing the scilab executable, the following error occurs:

error while loading shared libraries: cannot open shared object file: No such file or directory

Turns out I have installed, so the fix is:

sudo ln -s /usr/lib/x86_64-linux-gnu/ /usr/lib/x86_64-linux-gnu/
