Frequently Asked Questions About X-Win32 vs FastX

I have X-Win32 under maintenance. Do I have to pay for FastX?

FastX is available to X-Win32 customers at a discount.

FastX is great when connecting from home, but at work I prefer to use an XDMCP connection. Do I need both FastX and X-Win32 to do this?

If you need both X-Win32 and FastX, we offer a combination in which both products are discounted.

How are FastX connections different from Exceed OnDemand, VNC or NX connections?

FastX uses an RDP-based protocol. Exceed OnDemand uses a VNC-like protocol and NX is X11 based. All 3 have shown to b e slower than FastX in basic tests we have performed with 2D and 3D applications.

Why doesn't the FastX server support Solaris, HP/UX or AIX?

The Unix operating systems cannot support the RDP protocol on which FastX was designed. However, you can set up a Linux server on your network, install FastX and then run what we call "FastX Indirect" sessions to display Solaris, HP/UX and AIX.

I can no longer see my Gnome desktop when connecting with X-Win32. Our SuSE server uses Gnome3.

Linux desktops like Gnome3 are based on the latest OpenGL code that uses the "Direct Rendering Interface" (DRI) where the graphics are processed on the server hardware. Regular X servers cannot see this. Your best option is to switch to FastX and run the KDE or XFCE desktop.

What are some of the key differences between FastX and X-Win32?

  • X-Win32 is a traditional X11 based, client only PC X server. FastX is based on the RDP protocol and uses a client-server model.
  • X-Win32 connections like XDMCP, REXEC, SSH will cause the remote application to crash if the PC gets disconnected from the network. FastX sessions, under control of the FastX server, keep running on the remote server and users simply reconnect to their sessions.
  • X-Win32 has many configuration options due to the complex nature of X Windows. FastX simply displays the server’s graphics output and thus does not require any configurations such as turning on pseudo color support, backing store, etc.
