[Ltsp-discuss] Understanding LTSP

[A.J. M. <co...@da...>]

After looking through forums, documentation, manuals, wikipedia articles 
and more, my understanding of LTSP is thus:

* thin client boots from wake-on-lan, loads pxe from uefi
* thin client loads pxelinux, then initializes network from dhcp
* after downloading initrd via tftp, mounts nbd and nfs drives
* initializes the x window system via ssh forwarding and ltsp window manager
* finishes loading and stabilizes

one thing remains unclear, and no amount of googling and manual perusal 
has really enlightened me.

How does GLX forwarding work? i understand that the x server uses glx to 
access opengl-based 3D and 2D acceleration, and since the x server is 
running on the thin client, the rendering relies on the thin client's 
graphics card.

I don't mind this, since it's a lot easier to build a bunch of machines 
with beefy graphics cards and high-quality NICs than it is to load up on 
RAM, CPU cores, and very high quality motherboards, etc. etc.

If anyone knows exactly how GLX works with the X forwarding in LTSP, I'd 
appreciate it.

If anyone has tried using virtualbox or vmware over LTSP, please let me 
know how it went! Thank you in advance!
