If keyboard is *really* "dead" (at software level) then the kernel is dead too and you will not be able to use ssh or telnet to login into dead machine. If you can use ssh or telnet then you can use SysRq keys and there is no exceptions! SysRq keys handled by the kernel and cannot be blocked by userland process including X. For me there is no cases when I cannot use SysRq keys to switch to other console or kill X if kernel is alive. By definition, if you cannot use SysRq keys this is probably severe hardware failure (most likely RAM or video card, sometimes motherboard or overclocked processor). Theoretically this can happen because of severe failure in kernel drivers (especially proprietary ones) but in practice this never happened to me (I'm using Linux for many years but it should be noted that I never have tried ATI cards). In fact, even when kernel is broken and partially unusable (you cannot login to the machine anymore either locally or remotely) SysRq keys still work. In short if kernel is alive (for example, if you can use ssh or telnet to login remotely), SysRq keys will work no matter what happened to X. _______________________________________________ wine-users mailing list wine-users@xxxxxxxxxx http://www.winehq.org/mailman/listinfo/wine-users
