Hello, So, here is my report - not exactly the one we assumed : however :
last friday evening, reading briefly the doc, I understood that attaching gdb to X was dead simple, so I tried - and X froze - completely - it was late, thus I dropped it, and resumed the debug session now. It kept freezing. meanwhile, looking closely to the situation, I noticed that the doc mentions attaching to /usr/bin/Xorg; however, on my Ubuntu 10.04 (I have two desktops at home, one x86_64 and one i686), ps -ef|grep X shows /usr/bin/X running, not /usr/bin/Xorg; I verified more closely : /usr/bin/X is brought by xserver-xorg, which claims : " This package depends on the full suite of the server and drivers for the X.Org X server. It does not provide the actual server itself." Really ? whereas /usr/bin/Xorg is brought by xserver-xorg-core : and we have xserver-xorg-core-dbg, but no xserver-xorg-dbg, which can explain why, before freezing X, gdb claimed it found no symbols when attaching to X ... comparing X and Xorg : -rwsr-sr-x 1 root root 10,520 2010-04-09 04:07 /usr/bin/X -rwxr-xr-x 1 root root 1,901,280 2010-07-21 15:08 /usr/bin/Xorg two completely different executables : one with the sticky bit set, and so tiny ! This situation looks messy : don't you think ? I just connected through VPN at work : on CentOS 5.5, it's definitely /usr/bin/Xorg - which seems consistent with today's fashion (I am an old timer, remember ? I knew X11R6 on HP-UX and SunOS, not to mention Solaris) just to give it a try, in /etc/kde4/kdm/kdmrc, I replaced ServerCmd=/usr/bin/X with ServerCmd=/usr/bin/Xorg and restartedkdm ** Attachment added: "output from : gdb /usr/bin/X 2>&1 | tee gdb-X" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/620278/+attachment/1511275/+files/gdb-X -- random Xorg crash https://bugs.launchpad.net/bugs/620278 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
