> If you have a checkout of /usr/xenocara ... I have the cvsweb. I got the .core file with those instructions, run gdb with my current X. I am not sure if snapshots X is compiled with or without debug symbols. Looking at some functions headers, I think I should mention that in firefox the web page is loading a magnifier picture as a cursor as soon as you hover on that image. As for Xenocara recompile with debug symbols, is it hard to do it for a novice like me?
