Well, if it takes the 3-finger salute, it's not dead. init, which handles that sequence, remains alive, and can initiate the restart sequence (init level 6), with the shutdown scripts running so it can run bash and the like. (That's good, as it least it means you get to shut down gracefully and don't endanger any data not yet written to disk.) It would appear to be X that's dead, not the machine as a whole. You say you can't switch to console mode, but that can mean different things to different people. Does that mean you've tried Ctrl-Alt-F1, etc, to see if the VT switcher works? Also try Ctrl-Alt-Bkspc, which should (unless you've disabled it in your xorg.conf) kill X and return you to a console prompt. If none of those work directly, do you have magic sysrq turned on in your kernel? CONFIG_MAGIC_SYSRQ, located under the kernel hacking menu in menuconfig. If you are running a kernel with that configured in, you have a few more options as well. Even when the three-finger-salute doesn't work (of course, if it does, use it), you can still try Alt-Sysrq-S (emergency-sync filesystems, do this three times to be safe), Alt-Sysrq-U (unmount what can be unmounted, remount-read-only the rest), Alt-Sysrq-B (reboot). That's handled directly by the kernel, so as long as it isn't too far gone, you can still avoid most problems of an unclean shutdown. Of course, if the kernel is gone too, or at least gone far enough it doesn't trust itself to reliably write anything to the disk lest it write in the wrong place, this won't work, but it's always worth a try if Ctrl-Alt-Del isn't doing anything. However, that's for when things get /real/ bad. Since you can still do Ctrl-Alt-Del, you don't have to try the Alt-sysrq-s,u,b thing. There remain a couple other useful sequences to try, however. Alt-sysrq-k (SAK, secure-access-key/system-attention-key) normally kills everything running on the current virtual console; init normally restarts the login daemon after that, giving you a chance to log back in. This may work. Try Ctrl-Alt-F1 to switch to the first VC if necessary after that. Alt-sysrq-r (unRaw the keyboard mode) can also help, at times, particularly when X crashes. If your VT-switcher keys (Ctrl-Alt-F?) aren't working, sometimes that'll get them working again, so you can get a console to work in. If none of that is working, then the system is in pretty bad shape regardless, and initiating shutdown (either c-a-d or alt-sysrq-sub as necessary) is probably best anyway. However, at least in my experience it's rare that ctrl-alt-del works if I can't get a console using one of the methods above, so given that it /is/ working for you, it's fairly likely you can get a console /one/ way or another. Of course, that's assuming you hadn't already tried all that, but you didn't mention it, so I figured it's worth the shot. -- Duncan - List replies preferred. No HTML msgs.
