Just a few notes for anyone who is trying to use the Linux TWM wallet on Ubuntu.
The wallet did not work for me on 16 or 18. However, the wallet works for me on Ubuntu 20
On my laptop my max screen resolution is too small to fully fit the wallet on the screen (the bottom of the wallet was cut off by the bottom of the screen). A hacky work around is to first find the name of your screen device:
Then, once you have your monitor name, scale your screen using the command:
xrandr --output <MONITOR NAME> --scale 1.15x1.15
You can play around with the scaling amount, but 1.15 worked well for me.
After this I could use the wallet and see all parts.
Hope it is helpful to someone.
