ERROR:gbm_wrapper.cc(253) Failed to export buffer to dma_buf: No such file or directory

@rrslssr you can ignore them,
OR add
export ELECTRON_DISABLE_GPU=1before the npm start line in
~/MagicMirror/installers/mm.sh -
@sdetweil said in ERROR:gbm_wrapper.cc(253) Failed to export buffer to dma_buf: No such file or directory:
export ELECTRON_DISABLE_GPU=1
@sdetweil That did not work for those errors, but it did eliminate other errors further down.
I’ll just ignore these.
Thanks -

Is this still the right way to address these errors? This is what my
~/MagicMirror/installers/mm.shfile looks like:#!/bin/bash cd /home/mmuser/MagicMirror ''' if [ $(ps -ef | grep -v grep | grep -e wayfire -e labwc | wc -l) -ne 0 ]; then WAYLAND_DISPLAY=wayland-1 export ELECTRON_DISABLE_GPU=1 npm run start:wayland else export ELECTRON_DISABLE_GPU=1 DISPLAY=:0 npm start fi ''' export ELECTRON_DISABLE_GPU=1 DISPLAY=:0 npm startAnd I’m still getting the following errors:

@dathbe I tried to make it dynamically select, but that didn’t work, so its commented out
‘’’ is a bash block commentsomeone posted that npm run start:wayland worked for them to clear those errors…
-
@dathbe said in ERROR:gbm_wrapper.cc(253) Failed to export buffer to dma_buf: No such file or directory:
export ELECTRON_DISABLE_GPU=1
the default now is disabled…
and the env var has changed to
export ELECTRON_ENABLE_GPU=1
to turn it on -
@sdetweil
No luck. withDISPLAY=:0 npm start, I get the long list of errors, but everything seems to work ok with the mirror. withWAYLAND_DISPLAY=wayland-1 npm run start:waylandIt throws other errors and gets stuck in what seems to be a restart loop.

@dathbe yeh, thats what I found too…
maybe its labwc display now?from the labwc doc,
https://labwc.github.io/labwc-config.5.htmlit sounds like DISPLAY is the correct variable
The autostart file is executed as a shell script after labwc has read its configuration and set variables defined in the environment file. Additionally, the environment variables WAYLAND_DISPLAY and (when labwc is built with Xwayland support) DISPLAY will be defined -
I tried all three options in raspi-config > Advanced > Wayland (those being 1) X11, 2) Wayfire, and 3) Labwc), and was getting the same error on all of them. I went back to Labwc because my understanding is that is the current recommended.
I’ve tried many different combinations. Anything having to do with
start:waylandseems to truly fail and get stuck in a restart loop.npm run start:waylandtechnically works, but throws about 20 ugly error messages on start.Various options I’ve tried:
# Work with error messages DISPLAY=:0 npm start export ELECTRON_DISABLE_GPU=1 DISPLAY=:0 npm start export ELECTRON_ENABLE_GPU=1 DISPLAY=:0 npm start # Cause endless start loop npm run start:wayland export ELECTRON_DISABLE_GPU=1 npm run start:wayland export ELECTRON_ENABLE_GPU=1 npm run start:wayland WAYLAND_DISPLAY=wayland-1 npm run start:wayland DISPLAY=wayland-1 npm run start:wayland -
@dathbe restart loop is pm2, its job is to keep the app running
-
@sdetweil Ok. When I have some time, I’m going to test an install with 32-bit PiOS.
-
@dathbe 32bit is x11 only . as i recall
-
@sdetweil It appears to load labwc by default, but either way it didn’t do anything different – fails to start with
start:waylandand multiple phantom errors withstart. I guess I just have to close my eyes and not read the logs on startup. Though weird it’s doing it with my Pi 4B, but not my Pi 2B. -
@dathbe yeh some config setup, i think something in /boot/config. txt
-
@sdetweil In case for some reason it’s helpful, I’ve reviewed the contents of /boot/config.txt from my two devices (4B gets errors, 2B does not).
In 2B, not in 4B:
