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 qt6ct (Qt) and nwg-look (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 environment variable.

My external monitor is blank / doesn't render / receives no signal (laptop)

For Nvidia graphics - This issue appears to be resolved when using Nvidia Drivers 525.60.11 or later, but it may persist with older drivers.

Outside those, there is a way to fix it that might work for you though:

Option 1: Use only the external monitor

By using WLR_DRM_DEVICES=/dev/dri/card1 (or card0) you can force Hyprland to use only your dGPU, meaning your laptop's screen will be gone but your external one will work.

Option 2: Use all outputs, at the cost of battery life.

By switching your laptop to only use the dGPU in the BIOS, you might be able to get everything to work, at the cost of high battery usage.

Please note these are highly model-specific and might or might not work. If they don't, you're unfortunately out of luck.

You might try a USB-C to HDMI adapter though, maybe that could route the external monitor through the iGPU.

How do I screenshot?

Install grim 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).

For a more complete utility, try our own screenshotting utility: Grimblast.

For recording videos, wf-recorder, wl-screenrec or OBS Studio could be used.

Screenshare / OBS no worky

Check Screensharing.

Also install qt6-wayland if you plan to use obs.

How do I change my wallpaper?

See Wallpapers.

My games work poorly, especially proton ones

Use gamescope, tends to fix any and all issues with wayland/Hyprland.

How heavy is this?

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

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

My monitor has flickering brightness when I turn on VRR

Change the VRR option to 2 (fullscreen), so that it is only used in games. This happens because the brightness on some monitors can depends on the refresh rate, and rapidly changing refresh rates (for example, when the screen momentarily updates after pressing a key) will cause rapid changes in brightness.

How do I update?

Open a terminal where you cloned the repo.

git pull 
make all && sudo make install

If you are using the AUR (hyprland-git) package, you will need to cleanbuild to update the package. Paru has been problematic with updating before, use Yay.

How do I screen lock?

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

How do I change me mouse cursor?

  1. Set the GTK cursor using nwg-look.
  2. Add exec-once=hyprctl setcursor [THEME] [SIZE] to your config and restart Hyprland.

If using flatpak, run flatpak override --env=~/.themes:ro --env=~/.icons:ro --user and put your themes in both /usr/share/themes and ~/.themes, and put your icons and cursors in both /usr/share/icons and ~/.icons.

For Qt applications, Hyprland exports XCURSOR_SIZE as 24, which is the default. You can overwrite this by exporting XCURSOR_SIZE to a different value with env.

You can also try running gsettings set org.gnome.desktop.interface cursor-theme 'theme-name' or adding it after exec-once= in your config.

If you do not want to install a GTK settings editor, change the config files 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 nwg-look).

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.

Waybar workspaces no worky???

Waybar has a set of caveats or settings that you need to be aware of. See Status bars for solutions.

How do I autostart my favorite apps?

Using the window rules to assign apps to workspace you can 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).

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

exec-once=[workspace 1 silent] kitty
exec-once=[workspace 1 silent] subl
exec-once=[workspace 3 silent] mailspring
exec-once=[workspace 4 silent] firefox

How do 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

handle() {
  case $1 in monitoradded*)
    hyprctl dispatch moveworkspacetomonitor "1 1"
    hyprctl dispatch moveworkspacetomonitor "2 1"
    hyprctl dispatch moveworkspacetomonitor "4 1"
    hyprctl dispatch moveworkspacetomonitor "5 1"
  esac
}

socat - "UNIX-CONNECT:/tmp/hypr/${HYPRLAND_INSTANCE_SIGNATURE}/.socket2.sock" | while read -r line; do handle "$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 is the way to go.

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

~/.config/hypr/hyprland.conf

exec-once=dbus-update-activation-environment --systemd WAYLAND_DISPLAY XDG_CURRENT_DESKTOP

Make sure that your portals launch after this gets executed. For some people, they might launch before that has happened.

In such cases, a script like this:

#!/bin/bash
sleep 4
killall -e xdg-desktop-portal-wlr
killall xdg-desktop-portal
/usr/lib/xdg-desktop-portal-wlr &
sleep 4
/usr/lib/xdg-desktop-portal &

launched with exec-once should fix all issues. Adjust the sleep durations to taste.

How do I export envvars for Hyprland?

See Environment Variables

The env keyword is used for this purpose. For example:

env = XDG_CURRENT_DESKTOP,Hyprland

How to disable middle-click paste?

The middle-click paste action pastes from a separate buffer (primary buffer) than what the regular clipboard uses (clipboard buffer). Since the primary buffer is unrelated to the clipboard buffer, it's easy to simply keep the primary buffer empty, allowing the middle-click action to retain the rest of its functionality without having anything to paste. Run the following command (in your config with exec-once, for example) to achieve this:

wl-paste -p --watch wl-copy -p '' (wl-paste -p --watch watches for changes to the primary buffer, wl-copy -p '' clears the primary buffer)

Alternatively, you can simply intercept the middle-click action all together, via hyprland binds for example. The drawbacks to this solution are that 1. it disables the rest of the functionality of the middle-click action, such as auto scroll, closing browser tabs, etc., and 2. many applications (such as kitty) manually intercept the middle-click events and bind them to paste from the primary buffer themselves, bypassing the solution altogether. For this solution, add this bind to your config:

bind = , mouse:274, exec, ;. Note that the exact bindcode may vary, so you may want to check it with wev first.

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, change it. It's heavily advised to use full regardless of anything.

Useful Optimizations:

  • decoration:blur = false and decoration:drop_shadow = false to disable fancy but battery hungry effects.

  • misc:vfr = true, since it'll lower the amount of sent frames when nothing is happening on-screen.

How to fix games with window dancing?

Read this trick.

My apps take a long time to start / can't screenshare

See The XDPH Page.

You most likely have multiple portal impls / an impl is failing to launch.

My screenshot utilities won't work with multiple screens

Some programs like flameshot (currently) has limited wayland support so on most Wayland compositors, you will have to do few tweaks. For Hyprland, you can add these window rules to your config to make said programs work with both of your screens.

windowrulev2=move 0 0,title:^(flameshot)
windowrulev2=nofullscreenrequest,title:^(flameshot)

I cannot bind SUPER as my mod key on my laptop

Many laptops have a built-in function to toggle SUPER between single key press mode and hold mode. This is usually indicated by a padlock on the SUPER key.

First, install and run wev, then press SUPER. If you see a key press event followed by an instant key release event, then it's likely your SUPER key is set to single press mode.

On most laptops this can be fixed by pressing FN+SUPER and verified in wev. You should be able to hold SUPER and not see an instant release event. In case FN+SUPER doesn't work, consult your laptop's manual.

My VM doesn't receive keybinds I have set in Hyprland

This is expected, as Hyprland takes precedence.

A simple fix is to create an empty "passthrough" submap:

bind = MOD,KEY,submap,passthru
submap = passthru
bind = SUPER,Escape,submap,reset
submap = reset

set MOD and KEY to desired values.

By pressing the selected combo you will enter a mode where hyprland ignores your keybinds and passes them on to the vm.

Then, pressing SUPER + Escape will leave that mode.
