[Dri-devel] Simple example fails w/direct rendering
Hello,
This is an example from an opengl tutorial that I'm trying out. If I run it
with LIBGL_ALWAYS_INDIRECT it works fine, but with direct rendering I just
get a blank window. I'm using the radeon driver from recent CVS (checked
out yesterday anonymously) on a Dell Inspiron 4150 w/Radeon Mobility M7.
Any ideas?
Thanks,

I'm using the radeon driver from recent CVS (checked out yesterday anonymously) on a Dell Inspiron 4150 w/Radeon Mobility M7. So, the example is drawing a wire-frame cube and clearing the screen as fast as it can on a single-buffered display? What do you think the odds are on a fast video card that the video refresh logic will just happen to be displaying something when it's not cleared? Pretty close to 0 I'd say. The driver isn't broken. You only see it with indirect rendering because the drawing / clearing is slower, so the cube is on the screen for a larger amount of time. --- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.

Re: [Dri-devel] Simple example fails w/direct rendering
this is something to do with double buffering no sure what is going wrong though, probably getting a doubled buffered visual and using it as single or somthing... adding glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE ); to the main before CreateWindow and glutSwapBuffers(); to the end if display make it work for me on my mach64...
