Zhoujian, if you haven't done this before, this requires: - preferably not stripping debug symbols from X server when installing it (don't use "strip" command or "-s" argument for "install" command) - after starting X, attaching to it with Gdb from ssh console (display server issues need to be debugged from another machine): gdb <your X binary> $(pidof X) - typing "cont" in Gdb to continue X running - running the test case under X until X crashes - in the Gdb prompt after X crash: - typing "bt" command to get backtrace, - following with few "up" and "info locals" commands (type "info locals" after every "up" command)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
