Running GL applications through X forwarding is completely different than
running them locally. When going over the network, there is no DRM and
hardware acceleration. You can take this as a measure.
Also, if GL would support rendering over the network, it would most
happen on the server (in X speech, i.e. the machine you are connecting
and not the PowerBook. But again, DRM does not work over the network.
perhaps I explained myself wrong, I was too quick:
- I conntect remotely
- I launch X11 on the PowerBook
- I set DISPLAY to :0
this means glxgears is run on the PowerBook (local X server on PPC) ,
not on the remote computer ("remote) server", it is *not* displayed over
the network and draws full speed (about 70fps).
It is a convenient way to debug things and write emails from another system.
This is also why I wonder that it works (other applications still to not
work, but I want the simplest example to work first).
As soon as I am home and have access to my laptop again, I will give you
the remaining information you asked.
I will also compare glxinfo information and see what it says.
