shortcut-keys – Get Alt+SysRq Working on Dell Latitude E6530


I have a Dell Latitude E6530. The keyboard has a SysRq key (Fn+Home). However the magic keys (especially the famous REISUB) doesn't work.

SysRq is enabled in /proc/sys/kernel/sysrq (I get 1 if I cat this file).
It works from external USB keybord.

How can I have the Alt+SysRq+REISUB (in fact, Alt+Fn+Home+REISUB) reboot my system?

  • Press/hold both Fn and Alt
  • Press/hold Home/Sysrq
  • Release Fn
  • Press key (tested with T)
