Always Test the Hardware
by frankbell from LinuxQuestions.org on (#6GCPT)
Earlier today, when I tried to open LQ, my system did not respond. After a brief moment of panic and a reboot, I tried reseating the cables in my KVM and computer, with no effect.
Then I tried connecting the mouse directly to the computer, bypassing the KVM that I had installed to manage two machines. The mouse worked.
I rebooted the computer and the mouse still worked, but the keyboard did not. So I connected the keyboard directly to the computer, bypassing the KVM. The keyboard worked.
The KVM had given up the ghost after many years of faithful service. (For other reasons, I no longer need the KVM, so it's off to the recycling bin.)
The moral of this story is, always text the hardware. It may not be at fault, but, if it is, no amount of messing with software will solve the problem.
