snap-store - "Unable to create a GL context"

[sean-workman]

Is there an existing issue for this?

• I have searched the existing issues and found none matching what I'm reporting.

Bug Description

When I try to open the App Center I am met with a blank screen with faint text that says "Unable to create a GL context". If I run snap-store from the terminal I am met with the following errors. The last line of the error repeats over and over.

(snap-store:45825): Gtk-WARNING **: 20:21:19.846: GTK+ module /snap/snap-store/1248/gnome-platform/usr/lib/gtk-2.0/modules/libcanberra-gtk-module.so cannot be loaded.

snap-store

Expected behavior

Additional context

I found some other issues like mine but I've tried what has fixed things for them and it hasn't done it for me.

Thanks for the report - could you please provide some information about your graphics card and drivers in use by running

glxinfo -B

and

lspci -nn -k | grep -A2 VGA

@robert-ancell I'd appreciate it if you could have a look at this.

[sean-workman]

No worries, outputs are below:

Could you also run gtk3-demo and double-click on "OpenGL Area" to confirm that is working? (sudo apt install gtk-3-examples).

Also try flutter-gallery (snap install flutter-gallery).

The above will help work out if it's a driver issue or a snap issue.

[sean-workman]

The "OpenGL Area" worked fine. It rendered the triangle and I was able to spin it around with the x/y/z sliders.

flutter-gallery was less successful. The window opens and stays completely blank grey/white and this is what I see in the terminal:

❯ flutter-gallery
