Linux: amd64 AppImage fails to launch

[krikun98]

Describe the bug
amd64 AppImage fails to launch: I can see a black window for a fraction of a second, and then it just dies.
From the console the following log is produced:

./zmk-studio_0.1.0_amd64.AppImage                                                                              
Could not create surfaceless EGL display: EGL_BAD_ALLOC. Aborting...
zsh: IOT instruction (core dumped)  ./zmk-studio_0.1.0_amd64.AppImage

To Reproduce
Try to launch the AppImage

Expected behavior
I would expect the AppImage to launch.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment:

• Manjaro with KDE(Plasma 6.1.5)/Wayland, kernel 6.11.2-4-MANJARO
• App
• amd64 AppImage release 0.2.0

Also fails in an X11 session:

./zmk-studio_0.1.0_amd64.AppImage

I am using an AMD 7900XT with the open amdgpu driver.

I have a similar issue with the AppImage. The app starts but the windows
is blank.

I'm also having an issue with the AppImage window being blank. When run from the terminal I see similar output, only difference is I'm missing that first line:

Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...

Can folks give the environment variables mentioned here a try? mountain-loop/yaak#75 (comment)

[kmandarin-orange]

Just gave that a try, still got the same errors in terminal and same viewport behavior

[krikun98]

With the variables, the behavior changes - I get new errors:

WEBKIT_DISABLE_COMPOSITING_MODE=1 WEBKIT_DISABLE_DMABUF_RENDERER=1 ./zmk-studio_0.1.0_amd64.AppImage
Gtk-Message: 14:44:11.568: Failed to load module "xapp-gtk3-module"

** (app:130420): WARNING **: 14:44:36.852: atk-bridge: get_device_events_reply: unknown signature

And a white screen that's just open forever (as opposed to a black window that blinked on and disappeared before):

[petejohanson]

Please try the downloaded artifact from #92 and let me know if it fixes things for you as well. If so, I will get it merged and released. Thanks!

[kmandarin-orange]

The window contents now render correctly! Thank you for getting that working. I haven't had time to use it extensively yet but I was able to get to the studio unlock step, so that's a good sign.

[krikun98]

Doesn't seem to be working for me yet, unfortunately. Will report back once I can do a bit more testing.

[kmandarin-orange]

If it matters, I launched the AppImage as root, not sure if that'd affect things for you but it's worth a shot

However, WEBKIT_DISABLE_COMPOSITING_MODE=1 WEBKIT_DISABLE_DMABUF_RENDERER=1 ./zmk-studio_0.2.3_amd64.AppImage actually works now. Is there a way to use those variables as defaults?

Let me research the impact before we try forcing the values universally. Thanks for testing!

[petejohanson]

It really shouldn't require that. Can you please test running as a normal user?

[kmandarin-orange]

Yeah, it does launch but it gives me issues with "permission denied" errors when selecting a device. Forgot to mention that, my bad, that was just a separate issue I worked around but need to look into.

Does your user have correct permissions to the /dev/ttyACM# device?

[kmandarin-orange]

That was the issue, good catch! Had to add my user to the dialout group and restart, it now launches as expected and remaps keys successfully.

I've merged the build fix. I'm hesitant to try to enable those by default until:

• We've tested the impact more broadly.
• We understand scope of conditions that make this required.

For now, I'd rather add this to our (planned) Studio troubleshooting documentation.
