On dom0, looks like only the sync command(sysrq+s) of sysrq is enabled by default: [ctor@dom0 ~]$ grep -nH sysrq -- /usr/lib/sysctl.d/* /etc/sysctl.d/* /usr/lib/sysctl.d/50-default.conf:16:# Use kernel.sysrq = 1 to allow all keys. /usr/lib/sysctl.d/50-default.conf:18:kernel.sysrq = 16 /etc/sysctl.d/95-sysrq.conf:1:kernel.sysrq=1 I actually had to enable all by creating /etc/sysctl.d/95-sysrq.conf (as seen above). All info from here: https://www.kernel.org/doc/Documentation/admin-guide/sysrq.rst - 0 - disable sysrq completely - 1 - enable all functions of sysrq - >1 - bitmask of allowed sysrq functions (see below for detailed function description):: 2 = 0x2 - enable control of console logging level 4 = 0x4 - enable control of keyboard (SAK, unraw) 8 = 0x8 - enable debugging dumps of processes etc. 16 = 0x10 - enable sync command 32 = 0x20 - enable remount read-only 64 = 0x40 - enable signalling of processes (term, kill, oom-kill) 128 = 0x80 - allow reboot/poweroff 256 = 0x100 - allow nicing of all RT tasks -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
