Nothing renders / screen is empty / crash on opening first app

Possible causes:

Your themes are not set up properly, making apps crash.

Use something like qt5ct (QT) and lxappearance (GTK) (*for GTK you can also set up themes with envvars) to set up your themes.

Your PC is very, very old.

In that case, see the Installation Page and try compiling with LEGACY_RENDERER

For more info about bugs and crashes, see this wiki page

Me cursor no render?

Are you on NVIDIA? If so, then you have been a naughty boy and haven't listened to my tips on other pages. Use the WLR_NO_HARDWARE_CURSORS=1 envvar.

How do I screenshot?

Install grim-git and slurp

Use a keybind (or execute) grim -g $(slurp), select a region. A screenshot will pop into your ~/Pictures/ (You can configure grim and slurp, see their github pages)

How do I change my wallpaper?

Install hyprpaper, swaybg or any other wlroots-compatible wallpaper utility.

My workspace (2, 3, or any other) is like... bugged?

You did the below, unknowingly.

How do I mirror a screen?

Mirroring isn't officially supported, it's technically a bug, but it works. Make sure the screen you want mirrored is the same resolution as the source.

Then, just make them overlap in the layout, e.g. making the primary monitor at 0x0 and the mirrored one on 0x0 as well.

That creates an issue though, as the mirrored output also has to have an active workspace, and usually will be annoyingly taking 2,3 etc, while making them unreachable. An easy fix is to assign e.g. workspace=MIRROREDSCREEN,name:unused and never use it.

How heavy is this?

Not that much heavier than Xorg. If you want maximum performance, consider turning off the blur and animations.

Blur makes my GPU cry :(

You probably forgot to turn on decoration:blur_new_optimizations. Thank me later.

My monitor no worky!

Try changing the mode in your config. If your preferred one doesn't work, try a lower one. A good way to list all modes is to get wlr-randr and do a wlr-randr --dryrun

How do I get a coredump?

These instructions are ONLY for systemd. If you use anything else, you should know what you're doing.

Launch coredumpctl in a terminal. Press "END" on the keyboard to go to the end. Note the last (the one furthest to the bottom) crash that has /usr/bin/Hyprland as an executable. Remember the PID of it (the first number after the date in a given line) exit (Ctrl+C) type coredumpctl info PID where PID is the remembered PID. Send the entire thing.

How do I update?

open a terminal where you cloned the repo. git pull && sudo make clear && sudo make install

Screenshare / OBS no worky!

Yes, hello, this is Wayland.

Amazing gist just about that: https://gist.github.com/PowerBall253/2dea6ddf6974ba4e5d26c3139ffb7580

Please remember in OBS you need to select "Pipewire screen capture" as the source.

Howdy I screen lock???

Use a wayland-compatible locking utility using WLR protocols, e.g. swaylock.

How do I change me mouse cursor?

Use a tool like for example lxappearance to change the GTK cursor.

After that, add exec-once=hyprctl setcursor [THEME] [SIZE] to your config and restart Hyprland.

If that doesn't work, change the config files manually according to the XDG specification (Arch wiki link).

Make sure to also edit ~/.config/gtk-4.0/settings.ini and ~/.gtkrc-2.0 if not using a tool (like lxappearance).

Then, do a gsettings set $gnome-schema cursor-theme 'theme-name' and you're all good!

If it still doesn't work

GTK Settings no work / whatever!

https://github.com/swaywm/sway/wiki/GTK-3-settings-on-Wayland

My [program name] is freezing!

Make sure you have a notification daemon running, for example dunst. Autostart it with the exec-once keyword.

I want to use Waybar, but the workspaces don't work!

Copy the Waybar source, edit include/factory.hpp and add

#define HAVE_WLR
#define USE_EXPERIMENTAL

on top. If you want to also have sway modules (or any other defined in the file) add the appropriate defines.

All #ifdef HAVE_<thing> can be enabled by adding #define HAVE_<thing> on top.

Then compile according to the instructions on the Waybar github repo.

Use the wlr/workspaces module.

Please do not blame me for this, it's the Waybar dev that doesn't include experimental in the base binary for whatever reason.

Waybar doesn't show the active workspace!

Use the style for #workspaces button.active

How do I autostart my favorite apps?

Using the window rules to assign apps to workspace you can setup a session start script to open a bunch of applications on various workspaces. The following method will start these apps silently (i.e. without the flickering from workspace to workspace) and deassign the rule so that subsequent start of this app will not start it on the initially assigned workspace (which could be a drag if e.g. you want kitty to be started on ws 1 while you need kitty to open on any workspace subsequently).

Put the following in your hyprdland.conf: (example)

windowrule=workspace 1 silent,kitty
windowrule=workspace 1 silent,Subl
windowrule=workspace 3 silent,Mailspring
windowrule=workspace 4 silent,firefox
[...]
exec-once=kitty
exec-once=subl
exec-once=mailspring
exec-once=firefox
[...]
exec-once=cleanup_after_start.sh

where cleanup_after_start.sh script contains:

sleep 10
hyprctl keyword windowrule "workspace unset,kitty"
hyprctl keyword windowrule "workspace unset,Subl"
hyprctl keyword windowrule "workspace unset,Mailspring"
hyprctl keyword windowrule "workspace unset,firefox"

in sleep 10, the 10 is of course only a suggestion.

Howdy I move my favorite workspaces to a new monitor when I plug it in?

if you want workspaces to automatically go to a monitor upon connection, use the following:

In hyprland.conf:

exec-once=handle_monitor_connect.sh

where handle_monitor_connect.sh is: (example)

#!/bin/sh

function handle {
  if [[ ${1:0:12} == "monitoradded" ]]; then
    hyprctl dispatch moveworkspacetomonitor "1 1"
    hyprctl dispatch moveworkspacetomonitor "2 1"
    hyprctl dispatch moveworkspacetomonitor "4 1"
    hyprctl dispatch moveworkspacetomonitor "5 1"
  fi
}

socat - UNIX-CONNECT:/tmp/hypr/.socket2.sock | while read line; do handle $line; done

if you want workspaces 1 2 4 5 to go to monitor 1 when connecting it.

Please note this requires socat to be installed.

My tablet no worky??

Use Open Tablet Driver to configure your tablet. In the future it will be supported in the config. Until then, OTD.

Some of my apps take a really long time to open...?

~/.config/hypr/hyprland.conf

exec-once=systemctl --user import-environment WAYLAND_DISPLAY XDG_CURRENT_DESKTOP

My cursor in QT apps is too big!

The QT cursor size can be fixed by setting the envvar XCURSOR_SIZE=24. You should probably add it to your exported envvars.

How do I export envvars for Hyprland?

As with any Display Server, Xorg included, you should probably make a script to launch it, for example:

export AMONG_US=1
exec Hyprland

and launch that. (For Login Manager users, you can replace the "exec" entry in the .desktop file to point to your script)

I get random white flashes!

Try disabling VFR with misc:no_vfr=1

How do I make Hyprland draw as little power as possible on my laptop?

I assume you already have damage_tracking on full. If you don't, do it. It's heavily advised to use full regardless of anything.

Optimization options:

feel free to ignore any that you find causing issues

decoration:blur_new_optimizations = true

decoration:blur = false

decoration:drop_shadow = false

misc:no_vfr = false
