I have installed XFree 4.3.99.16 patched and kernel 2-4-23-pre9, following Bruce
instructions. The Acceleration started to work, for example Tuxracer works fine.
But in the application I am working at, we use some OpenGL windows and it always
happens that after two or three frames the output of one window is showed in ALL
the windows, making the acceleration unuseful. If I shut down the acceleration,
the program work properly (only very slow). I have compiled the program with
efence, and run it with ddd, here it is what I obtain:
Yesterday:
Program received signal SIGFPE, Arithmetic exception.

Today: (I don't know exactly what I changed, maybe I fixed something with GL
Libraries, I am sure now I am using the right ones)

disabling TCL support
New OGLW Created: 1-1
and then program blocks waiting until GDB gets ready (it never happens)
If I don'use ddd, the program continue to work but not properly (as I said, in
no time one sequence of images enters in all the windows) and exits (when asked
to do that) with a segmentation fault. Our program works with different threads,
one of them executes elaborations, and another draws the result of the
elaboration in Open GL Windows. We use libglut functions (I have installed the
last one, 3.7.1). Lines are drawn in the right windows, but images are not. Our
program works properly in all the other accelerated computers.
If you need other informations just ask.
Thank you!
