FreeDos 1.2 on Oracle Virtual Box

Had problems installing.

Fix is

make up your drive NEW

when you get to install from CDROM press tab

Insert "raw" without quotes in the line after memdisk

vis

/boot/syslinux/memdisk

/boot/syslinux/memdisk raw

Press enter

Each time it rebooted to continue install I added it, not sure if made any difference after the 1st though and too lazy to reinstall again for no reason to check it out.

Audio Recorder

sudo apt-add-repository ppa:audio-recorder/ppa
sudo apt-get update
sudo apt-get install audio-recorder

Not all Thumbnails showing in Preview

sudo apt-get install dconf-editor

Open dconf-editor

Go to path

org / gnome / nautilus / preferences / thumbnail limit

Limit for showing thumbnails is 10mb size picture

add 0 on end for 100mb or double it 20mb whichever you want

Swap space

Good tutorial on adding a swap space. I've been having memory freezes since adding my new Ultra widescreen monitor.

Back up Pi (on Mint)

To backup the Raspberry Pi SD Card

dd if=/dev/sdx of=/path/to/image

To restore

dd if=/path/to/image of=/dev/sdx
From here:https://raspberrypi.stackexchange.com/questions/311/how-do-i-backup-my-raspberry-pi

Check if Pi Zero Working (on MINT)

Remove SD card.

Micro USB to USB A male.

Plug in to USB on PC.

Plug Micro USB into USB port (not end of board Power micro USB) the other.

Open Terminal and type dmesg to check USB port connections.

Should see "Broadcom" come up as a connected device.

Wipe brow as not wasted a fiver by blowing Zero up. 

Kill

Just another note to myself.

Using Kill

Noticed my CPU was using 3 out of the 4 cores at 100% and the fan was pretty noisy.

I initially thought it was Cinnamon but it wasn't.

I opened Terminal and used Top

Top

This listed the top three processes being used by FoxitReader. Earlier I had accidently tried to open a file with it that was not PDF.

Top showed me the process PID

So a quick ALT & F2 to open a console and kill followed by the PID shown next to each of the instances killed these processes and my CPU use dropped like a stone.
