X startup and authorization

2010-05-24 Thread tom fogal

Debugging glX apps

2008-11-11 Thread tom fogal
I'm hitting an issue appropriately establishing a glX context (it seems), and I'm looking for a good way to debug it. Quick overview in case someone happens to recognize the issue: I'm getting a segfault in X functions when trying to initialize GLEW. XOpenDisplay has succeded, and I'm not sure
