[Linux, flatpak] Crash due to "Error code 2 received from xdg-portal"
Closed this issue · 8 comments
What happened?
Whenever I click on the NormCap icon, it wont launch it.
I also tried launching it from the terminal but that didn't work either.
How did you install NormCap?
FlatPak (Linux)
Operating System + Version?
Fedora 39
[Linux only] Display Server (DS) + Desktop environment (DE)?
Gnome 45 / Wayland
Debug log output?*

@jasiralavi thanks for the tip. I will install the AppImage version.
Yeah, unfortunately (screenshot) permission management on Wayland is quite broken and constant subject of change. Many 3rd party screenshot tools are suffering from that.
The upcoming NormCap 0.5.0 includes some workarounds to mitigate this issue, but until Wayland, or more precisely, the underlying xdg-desktop-portal protocol, which Wayland implements, gets improved, those workarounds are just tiny band-aids...
Related issues are:
Appimage is working without issues, but cannot add additional languages with that. Getting download error.
@jasiralavi, would you mind opening a new issue for that download issue, and attach a corresponding debug log? I think a language download error is not on my radar, yet.
(And if I see it correctly, the debug log you shared here is also about the screenshot error, not the download error?)

Sure. Done that here #562
This problem should be mitigated with the latest release. Could you please confirm?
I installed the flatpak through the gnome Software app.
There was a pop saying I'll need to give permission to manage screenshots, after clicking Ok.
However, I didn't see a second popup /window for that. It went straight to the 'how to use' startup window.
Anyways, it's working ok now.
The language download is working ok as well.
Thank you once again for the great app!
Here are the screenshots of the two windows, just in case anyone's curious.
Thanks for the info, @jasiralavi. Interesting, that you didn't see the second confirmation dialog, but I'm glad that it still worked. I also noticed in the past, that the behavior depends a lot on the versions of the desktop environment etc.
Let's hope that the underlying upstream issue in xdg-desktop-portal protocol gets fixed at some point, so we can get rid of this fragile workarounds. Progress on that front is tracked in #320.
I am closing this issue, please re-open it or create a new one if the problem occurs again.
