Hardware liberators and other #oldcomputers folks, can you give me some advice here?
I received a cheap Chinese-made laptop whose owner said is "not fast enough anymore." And there's another problem: the keyboard developed a problem where random keys on the built-in keyboard get "pressed" all the time, leading to an unusable system. If you open a terminal on it from a live Linux distro, soon it's littered with "^J^J^J^J^J^J^J^J^J^J^J^J^J^J^J^J^J" sequences and you can't run any commands on it. Or use GUI apps, since other keys like F-keys, Control, Alt and even arrow keys are pressed as well. If you've bound anything to Ctrl+Alt and a letter, guess what's going to be activated en-masse?
Still, to its credit, the machine has 6GB RAM, a fully working screen, WiFi NIC, hard drive and basically everything else *other* than the keyboard that can still be used well with Linux, so it's not quite yet a basket case. So what I'm planning to do? Nuke that keyboard - in a software way. I'm thinking that there's got to be a kernel module that does the talking to the built-in keyboard and touchpad. If I remove it without removing USB support, then listo - the whole thing might just become usable again.
Now the question: what is the (Linux) kernel module that is responsible for this communication? Am I right to assume that if I un'modprobe it, it will stop receiving built-in keyboard input completely?
Thanks, and boosts appreciated!
