 su -l "weston" -c "your_weston_command"
 su -l "weston" -c "glmark2-es2-wayland"

Weston is using pixman software composition instead of GPU hardware composition. This may be because you have not accepted the EULA at the beginning of the build...

 cat /etc/default/weston
WESTON_USER=weston
#Autogenerated
OPTARGS=--use-pixman

Please comment the "pixman" line in the file "/etc/default/weston"

 cat /etc/default/weston
WESTON_USER=weston
#Autogenerated
#OPTARGS=--use-pixman
 systemctl stop Weston-launch
Failed to stop Weston-launch.service: Unit Weston-launch.service not loaded.
 systemctl stop Weston-graphical-session
Failed to stop Weston-graphical-session.service: Unit Weston-graphical-session.service not loaded.

Please remove the capital letter in the word Weston. The correct command is:

 systemctl restart weston-graphical-session
 weston-simple-egl
weston-simple-egl: ../weston-10.0.0/clients/simple-egl.c:852:

Weston is probably started with the "weston" user. The correct commands are:

 su -l "weston" -c "weston-simple-egl"
 su -l "weston" -c "glmark2-es2-wayland"
 systemctl stop Weston@root.service
Failed to stop Weston.service: Unit Weston.service not loaded.
 systemctl stop weston
Failed to stop weston.service: Unit weston.service not loaded.
 systemctl stop weston-launch
Failed to stop weston-launch.service: Unit weston-launch.service not loaded.

Please use the full Weston service named "weston-graphical-session". The correct command is:

 systemctl stop weston-graphical-session

Note: You can list all systemctl services with the following command:

 systemctl list-units | grep -i weston 
 weston-image mypicture.bmp
mypicture.bmp: unrecognized file header 0x42 0x4d 0x1e 0x51

"weston-image" small application supports only jpeg, png and webp image files. Please convert your ".bmp" image file into one of these supported image file formats.

Note: The official source code of "weston-image" is in the file image.c and the related error message is in image-loader.c.
