Fails to launch with graphics error

[elcste]

I just installed (on Ubuntu 21.04), and when I try to run it I get graphics errors

$snap run alacritty

Thanks for reporting! I embedded most of the libraries inside the snap but looks like that's not enough. I'll see what I can do.

@elcste - Can you also please provide the output of this command:

LIBGL_DEBUG=verbose alacritty

Created a forum thread to make sure I'm on the right direction.

@elcste - do you have an nvidia card? can you please specify a little bit more information about your system? thanks!

Also, could you please try building u2104-10 branch and see if it's working for you?

[elcste]

@tunix No, my computer is an HP laptop with pretty boring specs: i5-8265U and Intel UHD 520 graphics.

If you tell me how to build it, I will try :-)

@tunix No, my computer is an HP laptop with pretty boring specs: i5-8265U and Intel UHD 520 graphics.

If you tell me how to build it, I will try :-)

First clone this repository. Then go to the branch by typing the following command: git checkout u2104-10

Then issue the following command to build the snap:

SNAPCRAFT_BUILD_ENVIRONMENT_MEMORY=4G snapcraft --debug

You need to install multipass + snapcraft if you don't have them.

[elcste]

I tried building it, on a different machine I have at work, but also with Intel graphics (just older). It stops when trying to prime mesa with this message:

+ snapcraftctl prime
The primed files for part 'mesa' will not be verified for correctness or patched: build-attributes: [no-patchelf] is set.
Issues while validating properties: The 'version' property does not match the required schema: 'lacritty_terminal_v0.13.0' is not a valid snap version string. Snap versions consist of upper- and lower-case alphanumeric characters, as well as periods, colons, plus signs, tildes, and hyphens. They cannot begin with a period, colon, plus sign, tilde, or hyphen. They cannot end with a period, colon, or hyphen.

[woutervb]

Just had a quick look, an possibly you are missing some search paths for the dri drivers; https://docs.mesa3d.org/envvars.html

Did a local (non snap) build and then checked of the loaded drivers are included in the snap, which they are, but since the snap changes paths, this might be the issue.

[tunix]

Hi,

I've just merged @woutervb 's changes and the builds are now in progress. Please test the latest snap and let me know if it now works for you. Thanks!

[elcste]

Yes, it works now!
