Rep: Reputation: 39 and gaming-keyboard: no caps/num/scroll lock leds during X session

I use exclusively Slackware 64 14.1 with Kernel 3.10.17 on my AMD FX 6300 six-core PC.

I was gifted with a USB gaming keyboard (GX-gaming Imperator Pro I - Genius).

Keyboard is fine. I don't care about fancy macro gaming keys. Only the basic input device. Both the numlock and caps lock, as well as scroll lock keys work fine in a typing perspective. But, pressing any of them don't illuminate the corresponding LED indicators while IN session. The indicators do work, on and off leds are illuminated, while I'm on a terminal OUT of But they do not light during session, though the lock keys do work - I just can't see the leds and I have to type anything to see if they are ON or OFF.

I found out over the net that this would work, probably because my keybord wouldn't be in UTF-8 mode:

# kbd_mode -u

Indeed, now I can see the leds during a X session.

However, it messes up with another keys: the ALT-F2, used to run a command, now opens a second terminal (tty2).

I wonder if anybody else has the same problem to try to find out a solution.

Thank you.

I've never heard of this one, but maybe you could force the LDEs to work. I presume Slackware still has xorg.conf? If so add an entry under InputDevice
Option "XkbOptions" "caps_led:caps,num_led:num"
I've used "grp_led:scroll" successfully in the past, so I don't see why re-setting the defaults shouldn't work — no guarantee offered, though!

It has worked, David, but sometimes I can't turn ScrollLock led on. Everything was solved when I upgraded to kernel 3.16.2 and X.Org 7.7 (Core 1.16.0). Marking this thread as solved.
