Well "date" won't hang but you won't actually see any output for it on the XTerm. But I'm unclear how switching to VT1 is going to work since that requires that X capture the VT keypress. If X is hung and not responding to keyboard and mouse inputs it's not going to see that keypress either and isn't going to switch. I think the best way to test in this situation is to SSH in from another machine and run commands like this over SSH. Even better would be a serial console. -- greg - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
