I am using a new keyboard, and trying to set it up to mimic the keyboard on my laptop. I'm using xmodmap on Ubuntu 14.04, and can't get it to work. I cleared the modifier keys like so :
xmodmap -e "clear mod1" xmodmap -e "clear mod4" xmodmap -e "clear Control"
And that works fine, afterwards the modifiers don't do anything. After that, I try to assign the Alt_R key to act as a super key, like so :
xmodmap -e "add mod1 = Alt_R"
However, the alt button then goes back to behaving like an alt button, instead of behaving like super and bringing up the Unity search when it's tapped. Is there a trick to getting the modifiers working with xmodmap?
Additionally, even after clearing control, with "xmodmap -e "clear Control", I can still use ctrl.
The keyboard I'm using is the das keyboard s ultimate, if that matters at all.
EDIT: A realization I made while messing around with xev and trying to solve the problem : When I run something like "xmodmap -e "keycode 133 = Alt_L" (keycode 133 is usually super), and then launch xev, when I look at the output it shows this :
KeyRelease event, serial 37, synthetic NO, window 0x2000001, root 0x9e, subw 0x0, time 179020, (-382,66), root:(406,118), state 0x40, keycode 133 (keysym 0xffe9, Alt_L), same_screen YES, XKeysymToKeycode returns keycode: 64 XLookupString gives 0 bytes: XFilterEvent returns: False
As you can see, it sees the key press as Alt_L. However, the key is still behaving like a super key, activating the Unity search when pressed.
