Postman not installed on ubuntu with snap [closed]

Question

I'm trying to install postman on ubuntu 20.04 running on chromeos using snap

I first ran:

~$ sudo snap install postman

which appeared to work:

edit:

~/node/scrapedatatree$ glxinfo | grep -i vendor
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
Vendor: Mesa/X.org (0x1af4)
OpenGL vendor string: Mesa/X.org


username@penguin:~$ ls snap/
postman

But when I run postman:

username@penguin:~$ postman
The disableGPU setting is set to undefined
Not disabling GPU
No protocol specified
The futex facility returned an unexpected error code.Aborted (core dumped)

edit:

$ glxinfo | grep -i vendor
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
Vendor: Mesa/X.org (0x1af4)
OpenGL vendor string: Mesa/X.org
 
 $ lspci | grep VGA
(no output)

$ sudo find /dev -group video
find: ‘/dev/.lxd-mounts’: Permission denied

edit2:

:/etc/X11$ ls
Xreset  Xreset.d  Xresources  Xsession  Xsession.d  Xsession.options  app-defaults  fonts  rgb.txt  xkb

There is no xorg so the command doesn't work

edit3:

echo $XDG_SESSION_TYPE - no output

echo $DISPLAY - :0

echo $WAYLAND_DISPLAY - wayland-0

Answer 1

Run with Wayland disabled by setting the variable to 1 before your snap run postman command:

DISABLE_WAYLAND=1 snap run postman or LIBGL_ALWAYS_SOFTWARE=1 snap run postman

EDIT: To disable hardware acceleration in general, create a configuration file for Xorg:

If /etc/X11/xorg.conf.d/disable-gpu.conf does not exist:

echo -e 'Section "Extensions"\nOption "GLX" "Disable"\nEndSection' > /etc/X11/xorg.conf.d/disable-gpu.conf

Applications installed with sudo that do not have full Wayland support - an ongoing issue with postman: https://github.com/postmanlabs/postman-app-support/issues/9746 - may have trouble displaying their GUI. You can grant xhost access to your user and root with the following command run before you run your application:

xhost +SI:localuser:root

This is more secure than a generic xhost +.
