Ian, First thing you need is to download the cvs tree and build it. You can follow the instructions on http://dri.sourceforge.net/doc/DRIcompile.html. If you don't want to override your distro's XFree, then follow instead Leif's instructions on http://www.retinalburn.net/linux/dri_HOWTO.html replacing mach64-?-?-?-branch for the branch you're interested (either HEAD or tcl-0-0-branch). All this process can be quite tricky on the first time you make it, so make sure that you have you new Xfree running properly before you start playing with it. After, go to the radeon Mesa driver sources (see http://dri.sourceforge.net/doc/faq/architecture.html#ED-DRIVER-WHERE) and start debugging them, either by putting debug output statements, or running gdb on it, like: gdb glxgears run (there is always a breakpoint here due to the SSE detection - it's best the time to add breakpoints in radeon_dri.so) break nauthy-function-in-radeon-dri-so continue (it should popup) list step step next print foo ... if your app segfaults then when you run it with gdb it will breakpoint there. You don't need to recompile the whole X when you change parts of it. Just do "make", (if you mess with header is better to do "make clean" first because the dependencies may be wrong) and then " su -c "make install" " When you got so far come to us again giving more details about the bug you're keen, and we'll give hints of places to look and answer any doubt you may have.
