dmenu is not displayed

[FallingSnow]

Running dmenu results in the below output but no menu is actually displayed. I have tried alt-tabbing and it is not listed.

$ dmenu
# find_driver: Trying DRM driver `intel'
# wld_font_open_name: Opening font with name: monospace:size=10
# wld_font_open_pattern: Loading font file: /usr/share/fonts/TTF/DejaVuSansMono.ttf

Just installed for Arch Linux via dmenu-wayland-git and wld-git. I'm on Gnome Wayland.

@FallingSnow Do you have a solution for Fedora?

[michaelforney]

dmenu reads all its stdin before displaying a window. This is how it works on X11 too. Please try

printf '%s\n' foo bar | dmenu

If that doesn't work, a log with WAYLAND_DEBUG=1 would be appreciated.

I have the same problem as well. The output for printf '%s\n' foo bar | dmenu is:

# find_driver: Trying DRM driver `intel'
# wld_font_open_name: Opening font with name: monospace:size=10
# wld_font_open_pattern: Loading font file: /usr/share/fonts/TTF/DejaVuSansMono.ttf

When running the command with WAYLAND_DEBUG=1 the output remains the same.

[michaelforney]

WAYLAND_DEBUG=1 should definitely produce some extra output. Are you sure it is exported in your shell?

[KubqoA]

Sorry, you are right my mistake. Here is the output with WAYLAND_DEBUG=1

I am using sway as my wayland compositor if that helps.

[michaelforney]

Oh, I see. As far as I know, there is no standard wayland protocol for displaying surfaces that need to be docked on the edge of the screen. This version of dmenu uses the swc_panel_manager protocol I wrote for swc (https://github.com/michaelforney/swc/blob/master/protocol/swc.xml). If the compositor doesn't support that protocol, it just exits with status 1 (it should probably print an error message though, to avoid confusion).

To make this work with sway/wlroots, you will need to change it to use the wlr_layer_shell protocol: https://github.com/swaywm/wlroots/blob/master/protocol/wlr-layer-shell-unstable-v1.xml

[KubqoA]

I assume that means I would have to modify the source of this project?

[michaelforney]

Yes.
