Thread: PS/2 keyboard w/USB adapter perpetually resets

i'm having keyboard problem, , have googled until eyes numb trying find precisely problem, or close it. apologies if has been asked , answered elsewhere.

got new computer, dell 8500, last month (march 2013), , installed lubuntu 12.10 dual boot windows 8. far good. new computer came wireless keyboard , mouse, use single usb dongle. mouse jittery @ first, solved using different usb port dongle, , that's not related current issue.

gave wireless keyboard "old college try," after month, didn't it. old, large, "clicky key" keyboard (dell sk-8110) big meaty keys. it's ps/2, while new computer has usb. no problem - got belkin ps/2 usb y-adapter, , connected keyboard purple part. (i still use wireless mouse.)

i've used 2 keyboard modifications years: "xset r rate 250 30" give delay/repeat that's liking, , trusty old 9-line xmodmap script turns capslock ctrl, , both ctrls (left , right) capslock. that's way it.

works - while. then, out of nowhere, typically after keyboard has been idle short while (maybe 30 seconds or minute), num/caps/scroll lock lights blink, , keyboard resets - losing xset , xmodmap settings. occasionally, lights blink mods stick; usually, though, keyboard resets. also, sometimes, keyboard locks up, , need unplug/replug usb connector. mods lost, in event. can run xset , xmodmap again, , mods back, it's intolerable happen perpetually while i'm trying work.

tried each mod individually, without other. same problem. tried command "setxkbmap -option ctrl:swapcaps" found somewhere, in place of xmodmap. less - turns left ctrl, not both, capslock. no matter; problem remains. wondered if wireless keyboard, sitting nearby, might somehow pinging computer once in while, confusing it. turned off, removed battery, , put in room! no difference; same problem.

expecting modern computer accept 8-year-old keyboard adapter, , couple of simple modifications? gets me works - while! it's if - os, perhaps, or computer hardware, or in adapter or keyboard - triggering reset occasionally, instead of leaving things alone.
