Hi Dave,

Thanks for the reply.

a) Are you suggesting that Vesa always uses swrast for 3D rendering? Was
reading some articles on the net and it seems like vesa driver can be
used with a DRI based 3D Hardware driver also. Would really appreciate
if you could elaborate here a little. 

b) Assuming i setup the vesa driver to work with DRI based 3D swrast
driver for 3D, would i be able to run 3D OpenGL apps on this setup
(which is using software components for both 3D and 2D drivers)? Are
there are limitations on the resolutions that would be supported?

c) what is the difference between a vesa driver and a dummy driver? Can
i use a dummy driver instead of the vesa driver in the above setup?
(will the answer for question (b) above be any different if i use dummy
driver instead of vesa driver?)

d) Does any of these drivers (Vesa and Dummy) use DRM?


a. Can all openGL Apps be run on the setup with the vesa driver? Are
there any restrictions on the reslolution supported? 
b. Will the dummy driver based config also do the same? i.e. swrast
usage for all OGL and GLX calls?
