You can recover system from this state by manually triggering OOM killer using Magic SysRq keys. (Alt+SysRq+F, provided you have SysRq enabled in /proc/sys/kernel/sysrq)
- lolc 6y agoThis is very useful! I have to look up this combination every other month when one of my systems starts thrashing.
- bscphil 6y agoIs there a version of this that works on typical laptop keyboards that don't have SysRq? I could map an unused key to it with xmodmap of course, but if my X server isn't responding I don't think that would help very much!
- garaetjjte 6y agoSysRq is PrintScreen, I think it should be present even on laptops?
- bscphil 6y agoOh! News to me, I definitely have it. Thanks!
