The default sysctl setting for kernel.sysrq in Ubuntu is 176 (and was in bionic and xenial) and it is shipped in /etc/sysctl.d/10-magic- sysrq.conf file. This file is provided by a required package from the minimal task, called `procps`.
176 enables: 128 - allow reboot/poweroff 32 - enable remount read-only 16 - enable sync command Do you have `procps` package installed on your system? Is anything else overriding that setting? If that setting is not suitable for you, I recommend to either modify /etc/sysctl.d/10-magic-sysrq.conf or to add another .conf drop in, with a higher number in /etc/sysctl.d directory to suit your system better. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1793369 Title: Ubuntu18.10:ppc64:s390x - Sysrq trigger disabled when writing to /proc /sysrq-trigger To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1793369/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
