Re: [Trisquel-users] how to use 1920*1080 res in Trisquel in Vmware workstation ?

[leny2010]

IIRC VirtualBox Guest Additions which you will need to use are non-free so  
don't.  The generic free software way to achieve the same result with any  
GNU/Linux virtual machine would be over the virtual network using one of a)  
VNC b) enabling XDMCP in the greeter (GDM in Trisquel's case) and running a  
native Xnest instance c) (the only really secure one) connecting with SSH and  
using its port forwarding to connect an native Xnest instance again.  You  
lose 3D acceleration for the guest's display with all three methods.

There's plenty on the web on how to do this with a GNU/Linux guest on a  
GNU/Linux host so a search would seem to be in order.  However, this 'W$ game  
machine' you've got is just begging to have Trisquel or Parabola as its only  
operating system so you can contribute to some free software game development  
projects by testing them.
