Public bug reported: When using Ubuntu 16.04 as an X2Go server and connecting to launch a graphical Java SWT application (like Eclipse or Jameica), the connection is canceled and x2goagent crashes on the server with a core dump. Analyzing this core dump with gdb reveals:
Core was generated by `/usr/lib/nx/../x2go/bin/x2goagent -extension XFIXES -nolisten tcp -nolisten tcp'. Program terminated with signal SIGSEGV, Segmentation fault. #0 0x00007f5ae0e46e3f in _XData32 () from /usr/lib/x86_64-linux-gnu/libNX_X11.so.6 This worked well in Ubuntu 14.04. Similar bugs are reported here: [1] https://github.com/ArcticaProject/nx-libs/issues/82 [2] https://github.com/atom/atom/issues/4360 [3] http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=938 According to [2], it is related to the X11 BIG-REQUESTS extension, which is either not supported by this X2Go version or not handled properly. Right now, this problem can be hackfixed by binary patching out "BIG-REQUESTS" to "_IG-REQUESTS" in libxcb.so.1. This is a very bad solution for a production system though.. Note that this problem cannot be reproduced using very simple GUI applications (like xmessage or gxmessage). Apparently, these don't lead to a X11 big request. ** Affects: ubuntu Importance: Undecided Status: New ** Package changed: kaccounts-providers (Ubuntu) => ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1622154 Title: x2goagent crashes in libNX_X11.so.6 in Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1622154/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
