> had some trouble getting this, not sure if its valid by the time I did gdb of usc while froze
Unfortunately the command used in gdb was 't a a b' which inserted breakpoints in all threads, instead of the correct 't a a bt' (note 'bt' vs 'b') which would print the backtraces :) So the log is not very informative. The lsof output shows that unity8 has *not* exhausted its fd namespace, so this is not an instance of https://bugs.launchpad.net/bugs/1495871. lsof was not run as root, so we didn't get fd information about USC (which runs as root). For reference, the exact invocations to use to get all the information next time this occurs: $ sudo gdb -p $(pidof unity-system-compositor) (gdb) thread apply all backtrace full $ sudo lsof -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1491566 Title: unresponsive shell including power button doesn't blank/unblank display To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1491566/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
