bug#53003: 29.0.50; Wrong key modifiers

[Juri Linkov]

Some recent change broke the Hyper key modifiers.

After this change typing the Hyper key with arrows shows

  s-<right> is undefined

Before this change it was

  H-<right> is undefined

For this key xev reports keycode 133 (keysym 0xffed, Hyper_L)

Please show the output of `xmodmap'.

Do you see a line where Hyper is on the same line as Super, something
like this?

mod4        Hyper_L (0x42),  Super_L (0x85),  Super_R (0x86),  Super_L (0xce),  Hyper_L (0xcf)

(The keysym reported by xev does not really matter: that is not how X11
virtual modifiers work.)

Many X servers are misconfigured that way, causing Super to be
recognized as Hyper for the majority of users.  The recent switch to
using XKB for detecting virtual modifiers solved that problem, but
potentially caused this one as well.

The correct solution is to remove the Hyper keys from the real modifier
Mod4, and move them to (if not already occupied by another virtual
modifier) Mod5.

But I cannot tell you how to do that in concrete until I see the
output of `xmodmap' on your system.

Thanks.

Indeed, Hyper and Super are on the same line.

The above xmodmap was created by enabling the option in Keyboard Preferences:
"Alt/Win key behavior" -> "Hyper is mapped to Win".

I tried to disable this option and got such xmodmap:

mod4        Super_L (0x85),  Super_R (0x86),  Super_L (0xce),  Hyper_L (0xcf)

and still Super is used instead of Hyper.

But I already replaced all mentions of 'hyper' with 'super' in my init file,
so if you think there is no bug, then you could close this report.

Thanks, closed.
You could try placing this text in your ~/.Xmodmap and loading it, if
you want to gain the use of both Hyper and Super:

  remove mod4 = Hyper_L
  add    mod3 = Hyper_L

Thanks.
