I plan to meet a private seller in a few days to buy a USB keyboard. What do you suggest I do to test that the keyboard is 100% okay?

I mean, I plan to press every key in every row. Anything I should do/know/test/ask/etc?

Thanks.

What's the price difference here - keyboards are not that expensive and you'll have the comfortable feeling of a warranty with a new one :wink:

I'm currently overseas. $3 for this used one vs $5 for a new one that is not light-up and is from a store that has a bed reputation in the country. haha

Code: Select all

xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'
This will return the key codes and descriptions - e.g.

Code: Select all

67 F1
68 F2
69 F3
70 F4
71 F5
72 F6
73 F7
74 F8
75 F9
76 F10
41 f
42 g
52 z
64 Alt_L
52 z
37 Control_L
64 Alt_L
116 Down
113 Left
111 Up
114 Right
118 Insert
119 Delete
115 End
110 Home
112 Prior
117 Next
Some keys like the print screen and menu may not get displayed.

Check that x11-utils is installed.

Good luck :wink:

There's lots of seas. We're all overseas, from most other people's perspective.
