Yes, it would be good if you could run that apport command once the system is booted.

Are you waiting a few seconds after each magic key. This gives the corresponding command time to actually do its job.

Another thing you could try is by performing the same task logged in with an ssh session. This is done by sending characters to the file /proc/sysrq-trigger :

$ echo r | sudo tee /proc/sysrq-trigger
$ echo e | sudo tee /proc/sysrq-trigger
$ echo i | sudo tee /proc/sysrq-trigger
$ echo s | sudo tee /proc/sysrq-trigger
$ echo u | sudo tee /proc/sysrq-trigger
$ echo b | sudo tee /proc/sysrq-trigger
