This shouldn't happen, but I've got a Linux computer with the clock frozen at an hour ago and unsaved work that I can't access
Does Magic SysRq always work? [snip] A website took out Firefox's JS process, which coincidentally manages Gnome's UI. System becomes slow, eventually locks up. I suspect that a process goes mad and eats all memory. Machine has fallen off network because of this, so no SSH for me
A Linux based system used to be very reliable but I find as the environment around the kernel has become more complicated the more unstable it has become. I never used to have my desktop lock up but it does happen now and then in recent years. If the desktop appears to be locked up there are two options. One is to ssh in, which you said wasn't possible in this case. The other is to attempt to switch to a text console using Ctrl-Alt-F1. If you can do that, try to login and see if you can then gain control of the system. It may take time as the system is probably going to be responding slowly due to whatever caused the lockup of the desktop. -- Cheers!
