linuxlite and ubuntu midi and wave players

in linuxlite and ubuntu to get midi and wave players to work you need to install some packages such as sox and timidity

# aptitude install sox
# aptitude install playmidi
# aptitude install gsequencer
# aptitude install timidity
# aptitude install wildmidi

 

then download some midifiles such as

• https://freemidi.org/download-9185
• http://www.midiworld.com/files/2943

 

you can then play .WAV files and .MIDI files

$ play /boot/startupsound.wav
$ wildmidi Downloads/Mike_Oldfield_-_Moonlight_Shadow.mid
$ timidity Downloads/Mike_Oldfield_-_Moonlight_Shadow.mid

 

timidity has an amazing karaoke mode too

Carried away by a moonlight shadow
He passed on worried and warning
Carried away by a moonlight shadow.
Lost in a river last saturday night

linuxlite ubuntu unattended upgrades

linuxlite and ubuntu gnu/linux installs may have automatic unattended upgrades installed and enabled

to check the status of your system

$ aptitude show unattended-upgrades

if installed you can disable it by editing /etc/apt/apt.conf.d/50unattended-upgrades or remove the unattended-upgrades package

# aptitude remove unattended-upgrades
# rm /etc/apt/apt.conf.d/50unattended-upgrades
# reboot

 

https://github.com/chef/bento/issues/609

In past versions of Ubuntu, unattended package upgrades were handled by creating a cron job in /etc/cron.daily responsible for running apt. With 16.04 and the shift to systemd, unattended upgrades are handled by a systemd unit. The new systemd unit has OnCalendar set to 6am and 6pm, along with Persistent set to true. The result is that a full apt-get update && apt-get ugrade will run the first time the box boots, in order to “catch-up” with missed runs.

run cat /proc/cpuinfo to see what cpu chip & microcode version you have

$ cat /proc/cpuinfo

have a look at your logs to see if you have any microcode patches

dmesg | grep "microcode"

journalctl -b -k | grep "microcode"

 

you need to enable nonfree deb/rpm repos so you get access to microcode packages

deb http://deb.debian.org/debian jessie main contrib non-free
deb http://security.debian.org/ jessie/updates main contrib non-free

 

then install the microcode package

aptitude update
aptitude install amd64-microcode

 

check your kernels params and reboot

Notes

Unfortunately, the license of the microcode update data from AMD and Intel are not compatible with the Debian Free Software Guidelines.
Therefore, microcode update data will be available through the non-free distribution. The new processor microcode update system is available for both non-free Wheezy and non-free Squeeze (through the backports repository).

Meltdown (the vulnerability affecting only Intel chips) cannot be fixed with microcode updates alone and requires changes to core OS functionality, which may reduce performance further.

Spectre (the vulnerability affecting Intel, AMD and ARM chips) may be able to be worked around with microcode updates alone.
