trisquel on virtualbox / screen reso.

i belive there is a option that will stretch the display to fit the screen in virutalbox
but i dont know if you can increase the resoulution

you must relise that using non-libre software
software to run a virutal machine with trisquel dose not
increase your privacy and definitly dosent increase controll
you have over your computer

the files that are used to store the virutal machine data
are still controlled by the host operating system osx and apple and a goverment could acsess them if they wanted too

using a vm to run trisquel dosent improve the bad operating system your running

it is possible though to run trisquel as the main os on macs

here is a post about it:

but my advice would be to sell your mac and buy a libre friendly computer you can get good ones here:
http://libre.thinkpenguin.com

but if your mac has gone down in value and you need somthing cheaper the good news is libre software tends to work well with old computers and if anything dosent work like wifi etc then you can get a usb libre wifi card form here:

i recently got a good pentium4 machine for £24

btw i dont work for think penguin there are many other libre hardware distributors:

also you can find hardware reported to work with libre software here:

It is possible to edit `/etc/default/grub`, change the `GRUB_GFXMODE` variable, use `sudo update-grub2` then reboot. However, the GFX mode must be available, and strange resolutions are rarely available.
