Question 5

What about video card support (VGA)?

Accepted Answer

Currently AlphaVM does not support a graphic controller (VGA). However, most graphic applications using X-Window/DECWindow can be redirected to a remote display. This display can be located on the machine that hosts AlphaVM.  One would need to run an X-server on that machine. On Windows we recommend VcXsrv X-server. Linux usually has own X server, if the graphic environment is installed.

Is OpenVMS supported on AlphaVM?
