[Bug 532845] Re: [Lucid] Option NoTrapSignals ignored when debugging xserver
In the current version xserver-xorg-core 2:1.7.6-2ubuntu7 Option NoTrapSignals works correctly. I use Kubuntu and I have created a file /usr/lib/X11/xorg.conf.d/01-server.conf to give the option (but there are of course many other possible places) In /var/log/Xorg.0.log you can see the difference when the server crashes. By default there is a backtrace, with the NoTrapSignals there is none. Also in gdb you can see the difference. After a SEGV you can continue without the option (the handlers will be run and then Xorg will exit). With NoTrapSignal you cannot continue after a SEGV, the process has already been terminated. -- [Lucid] Option NoTrapSignals ignored when debugging xserver https://bugs.launchpad.net/bugs/532845 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

I tried to get Xorg core dump with no success. Looks like, that option NoTrapSignals has no effect. -- [Lucid] Option NoTrapSignals ignored when debugging xserver https://bugs.launchpad.net/bugs/532845 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

I found out, what prevents gdm/Xorg from creating core dump: soft core limit is set to 0 for these processes. -- [Lucid] Option NoTrapSignals ignored when debugging xserver https://bugs.launchpad.net/bugs/532845 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

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help. ** Changed in: xorg-server (Ubuntu) Status: Incomplete = Invalid -- [Lucid] Option NoTrapSignals ignored when debugging xserver https://bugs.launchpad.net/bugs/532845 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

[Bug 532845] Re: [Lucid] Option NoTrapSignals ignored when debugging xserver
@ogerlich - thanks for providing that info, but we would like to see it from the original reporter. We may want to send this bug report upstream, but upstream has a hard and fast rule that logs from someone other than the original reporter are not acceptable. The reason for that is that quite often with X.org bug reports, two people may *think* they have the same issue based on commonality of symptoms and/or hardware, but in truth they have separate issues and mixing the report and the files can cause the developers some confusion. If this bug report seems not to be getting attention, I would encourage you to file a new bug report with this data, and simply reference this bug report in your bug description. ** Changed in: xorg-server (Ubuntu) Status: Incomplete = New ** Changed in: xorg-server (Ubuntu) Status: New = Incomplete -- [Lucid] Option NoTrapSignals ignored when debugging xserver https://bugs.launchpad.net/bugs/532845 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
[Bug 532845] Re: [Lucid] Option NoTrapSignals ignored when debugging xserver
Same problem here: X crashes (apparently reproducably) when using Lucid Netbook Edition 2D, entering password to unlock keyring, and pressing Enter. But Xorg.0.log.old only shows its tiny backtrace and Caught signal 3 (Quit). Server aborting, rather than triggering Apport. I have added the NoTrapSignals config option but it doesn't make a difference. Does that option not apply for signal 3? ** Attachment added: dmesg.txt http://launchpadlibrarian.net/40647432/dmesg.txt -- [Lucid] Option NoTrapSignals ignored when debugging xserver https://bugs.launchpad.net/bugs/532845 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

Hi intuitivenipple, Please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you're using a custom /etc/X11/xorg.conf please attach that as well. [This is an automated message.
