You don't need to worry about anything in between. The 'Untrap Signals' bit disables Xorgs own signal handler, and then the 'Post-mortem backtrace' section tells you how to get Xorg to do a core dump when it crashes, which you run gdb on afterwards.
I forgot to mention, you will need to install libgl1-mesa-dri-dbg, xserver-xorg-core-dbg, xserver-xorg-dbgsym and libc6-dbg. To get all of these, you should add the following line to your /etc/apt/sources.list: deb http://ddebs.ubuntu.com hardy main universe Then run: sudo apt-get update sudo apt-get install libgl1-mesa-dri-dbg xserver-xorg-core-dbg xserver-xorg-dbgsym libc6-dbg -- [Intrepid] Intel graphics card only runs with NoDRI option https://bugs.launchpad.net/bugs/277709 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
