Super + left Shift + Right arrow keybinding not recognized

[leibniz2266]

I found an issue where the keybinding Super + Shift + Right (Right arrow) is not triggered when using Left Shift, but does trigger correctly when using the Right Shift key. Other keybindings with Super + Shift + Left or other directions work as expected with both Shift keys.

This seems to be a bug in how Hyprland handles specific modifier combinations

I have the following keybinds in ~/.config/hypr/hyprland.conf:

bind = Super+Shift, Left, movewindow, l
bind = Super+Shift, Right, movewindow, r
bind = Super+Shift, Up, movewindow, u
bind = Super+Shift, Down, movewindow, d

After reloading Hyprland with these bindings:

When I press Super + Left Shift + Right, nothing happens
When I press "Super + Right Shift + Right`, my window moves right (as expected)
The other directions (Up, Down, and Left) all work as expected with both Shift keys

I checked wev and confirmed that my keypresses are being detected correctly.

For context, here's my environment:
Distro: Arch Linux (started with a minimal install)
Keyboard Layout: US QWERTY
Hyprland Version: 0.49.0-1
Keymap model: pc105+inet
No remapping tools are installed

Has anyone else seen anything else like this?

can you post a log of wev when you do super + left shift + right? (disable your binds first)

in general, I think it's something hardware-related. Does the bind work elsweyr? (kde/sway)

[leibniz2266]

Yeah, I had Plasma installed on this laptop before with that bind moving a the active window to the next workspace. That's why I'm so weirded out by it not registering the bind with Left Shift, but it working just fine with Right Shift.

Interestingly, wev has the same output/log of whether I press Super Shift Left or Super Shift Right, but only the Left bind works. I'm gonna take another look through of the wiki and see if there's something about this somewhere. Might be something else going on at this point?

check two things:
remove the binds and press the combo on wev - it should show the arrow press event

add back the binds and press the combo on wev - it should not show the arrow press event

[leibniz2266]

Turns out it's a hardware-side issue and not a Hyprland issue, confirmed via showkey --scancodes in a TTY. My laptop's keyboard blocks the combo at a low level, so I must have misremembered my old Plasma keybind.

To double check, I got a cheap external keyboard just to test Super + Shift + Right on it, and was successful on Hyprland.

So sorry for taking up your time on this, I should've thought of this sooner.

that's what I thought. Oh well, at least we got it sorted :)
