Getting the log
If you are in a TTY, and the hyprland session that crashed was the last one you launched, the log will be printed with
cat /tmp/hypr/$(ls -t /tmp/hypr/ | head -n 1)/hyprland.log
feel free to save it to a file, save, copy, etc.
if you are in a Hyprland session, and you want the log of the last session, use
cat /tmp/hypr/$(ls -t /tmp/hypr/ | head -n 2 | tail -n 1)/hyprland.log
Crashes at launch
Diagnose the issue by what is in the log:
sWLRBackend was NULL!
-> launch in the TTY and refer to the wlr logs in RED.Monitor X has NO PREFERRED MODE, and an INVALID one was requested
-> your monitor is bork.- Other -> see the coredump. Use
coredumpctl
, find the latest one's PID and docoredumpctl info PID
. - failing on a driver (e.g.
radeon
) -> try compiling withmake legacyrenderer
, if that doesn't help, report an issue. - failing on
wlr-xxx
-> try compiling withmake legacyrenderer
, if that doesn't help, report an issue, and also refer to the TTY wlr logs in RED like in the first point. - failing on
Hyprland
-> report an issue.
Crashes not at launch

Building the Wayland stack with ASan
If requested, this is the deepest level of memory issue debugging possible.
Prepare yourself mentally, and then:
recommended to do in tty
clone wayland (git clone --recursive https://gitlab.freedesktop.org/wayland/wayland
)
clone hyprland (git clone --recursive https://github.com/hyprwm/Hyprland
)
edit your config to have a terminal that will launch:
bind = SUPER, Q, exec, LD_PRELOAD=/usr/lib/libasan.so kitty
(I put kitty, on SUPER+Q
can be anything)
add this env to reset ASAN_OPTIONS for children:
env = ASAN_OPTIONS,
wayland:
meson ./build --prefix=/usr --buildtype=debug -Db_sanitize=address
sudo ninja -C build install
hyprland:
cmake --no-warn-unused-cli -DCMAKE_BUILD_TYPE:STRING=Debug -DWITH_ASAN:STRING=True -S . -B ./build -G Ninja
cmake --build ./build --config Debug --target all -j`nproc 2>/dev/null || getconf NPROCESSORS_CONF`
Exit Hyprland to a TTY, cd to the cloned hyprland, and launch it:
ASAN_OPTIONS="detect_odr_violation=0,log_path=asan.log" ./build/Hyprland -c ~/.config/hypr/hyprland.conf
open your terminal
to open any app just add LD_PRELOAD=/usr/lib/libasan.so
to the beginning of the cmd
Do whatever you used to do in order to crash the compositor.
Go to ~
or cwd
and look for asan.log.XXXXX
files. Zip all and attach to the issue.
once you are done, to revert your horribleness of no app opening without the ld preload just go to the cloned wayland and do
sudo rm -rf ./build
meson ./build --prefix=/usr --buildtype=release
sudo ninja -C build install
