Can't copy on console

Dioswilson · 2024-09-08 03:45:57

Ever since I changed laptop I have been experiencing an issue where I can't use Control-Shift-c to copy content from console.
Control-c does work.

I used `showkey` to see what was being registed and I noticed that when pressing those 3 keys I got only 42 and 29 but no 46(c's keycode)

Can someone help me out with this one?

It might be worth checking if your keyboard only has 2-key rollover? I think most keyboards let you press more than 2 at a time, but maybe it's a "mode" that got switched into? It's at least a simple thing to check.

Is this on X11?
Run "xev" (no filter!), press ctrl+shift+c and post the output.

You could also just try an external keyboard, because I think Smie is right on the money.

Sorry for the delay guys, here is my response.

Might be true but not sure how to test it. I used https://en.key-test.ru/ to test and while both control+shift are pressed I can't press z,x,c,m

Here is `xev`'s output: https://pastebin.com/rTicr55m

I tried with another keyboard and it did work.

There's no event between pressing Control_L and releasing Shift_L and w/

I tried with another keyboard and it did work.

you may try whether you're getting events in "sudo evtest" but this is a partial 2k rollover.
Have you tried a combination involving right shift and/or control?

If i press left control and right shift or right control and left shift then it works. also tried with evtest and same thing is observed.

It's a HW limitation - you'll not be able to do anything about that - though sometimes you can "dance" over the keys (quickly let go of one while you're pressing the next)

Thanks for the tip. Sad MSI sells a laptop with such uncapable keyboard
