[sldev] Ubuntu Runtime Error SDL

[truxpin at adsl-209-233-23-82.dsl.snfc21.pacbell.net]

> What graphics card do you have?

The ubuntu machine has nVidia GeForce2 MX400. Nothing spectacular, but fwiw
it works ok under win2000 with LL's SL clients.

> Is your display using hardware OpenGL acceleration?

The box says "OpenGL ICD for Win98 & 2000.

> I've include a patch that tries a 16 bit depth buffer if the initial 
> OpenGL context fails.

I applied this and it does the trick. Console message are attached for
where the patch runs. Client screen comes up and I am able to connect to
MG. It is very slow, 0.7 frame rate, (running from build directory) but that
is another issue.

> ... post the visuals of glxinfo for your display.

glxinfo dump attached after console messages.

Is the problem a lack of flexibility in the client, a mis-match in libraries
or some setup problem of ubuntu, Xwindows or the machine leading to
lessening of the graphics capabilities?

Thanks for you help!
