Kernel panic when pressing alt+PrtScn+c in Ubuntu
What is this? Even when screen locked I've got kernel panic. Why sysrq is turned on by default? How can I trust Ubuntu competence after this kind of stuff.
- geekishmatt 13y agoaccording to http://en.wikipedia.org/wiki/Magic_SysRq_key http://en.wikipedia.org/wiki/Magic_SysRq_key PrtScn+C means "Perform a system crash. A crashdump will be taken if it is configured."

- geekishmatt 13y agoaccording to ubuntu documention you need to press alt+PrtScn simultaneously for any sysrq action
- holms 13y agowhy you need this in the first place? I think I'll troll some colleagues around. Although screen is locked, I'll just push alt+PrtScn and "c" to create a kernel panic. Cruel? Yes. Who's problem is that? - CANONICAL
- anan0s 13y agosysrq ftw. Really useful option. AFAIK alt-sysrq-e and -i are disabled by default in new kernels
