Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome #1429

aryoda · 2023-04-25T23:04:12Z

The user @topas-rec reported in #1421 (comment) a failing unit test on ARCH Linux caused by this additional (not expected) warning in the actual output:

Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

Furthermore this warning occurs if the optional package qt5-wayland is not installed:

qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""

System info:

$ echo $XDG_SESSION_TYPE
wayland

$ echo $QT_QPA_PLATFORM


$ echo $XDG_CURRENT_DESKTOP
GNOME

using git PKGBUILD backintime-git still fails on testing

Yes, the PKGBUILD does not yet use my fix (commit f056d90) because it is not yet merged.

I will merge it ASAP since the warning message to be ignored is the same...

Update: Pull request created (see below)

* Fix #1429 (Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome) Also ignores the qt.qpa.plugin warning: qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""

aryoda · 2023-05-03T09:03:39Z

The fix is merged into the dev branch now: 66d248f

topas-rec · 2023-05-06T06:41:30Z

Tried to test it - but I still get the error.

I changed to the latest dev version, installed qt5-wayland, exported export QT_QPA_PLATFORM=wayland.

Results are in the log with checks for the variables set and a cat of the file CHANGES to show that it is the dev version used for the build.

* Project: Renamed branch "master" to "main" and started "gitflow" branching model.
* Fix bug: Add support for ChainerBackend class as keyring which iterates over all supported keyring backends (#1410)
# Fix bug: Unit test fails on some machines due to warning "Ignoring XDG_SESSION_TYPE=wayland on Gnome..." (#1429)

One of three(?) failing messages:

Should that work in the way I set up everything?
Am I missing something?

@topas-rec THX for your details, I think I have found the problem and will fix the fix.

Edit: The reason is that the additional output of Qt5 that shall be ignored, is prefixed with Warning: and I forgot to include this in the exclusion list (which is checked via startswith, not "contains"):

\nWarning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.\n
