The flatpak apps don't seem to have permission to connect the X server on $ flatpak -v run org.gnome.Todo XA: Allowing x11 access XA: Allowing wayland access XA: Running 'bwrap --args 13 /usr/libexec/flatpak-dbus-proxy --fd=15 unix:path=/run/user/1000/bus /run/user/1000/.session-bus-proxy-W3BYSY --filter --own=org.gnome.Todo --own=org.gnome.Todo.* --talk=org.gnome.evolution.dataserver.Sources5 --talk=org.gnome.evolution.dataserver.AddressBook9 --talk=ca.desrt.dconf --talk=org.freedesktop.portal.* --talk=org.gnome.OnlineAccounts --talk=org.gnome.evolution.dataserver.Subprocess.Backend.* --talk=org.gnome.evolution.dataserver.Calendar7' No protocol specified (gnome-todo:2): Gtk-WARNING **: cannot open display: :99.0 $ xhost + $ flatpak -v run org.gnome.Todo (the app runs ok) In my opinion there should be no need for manual xhost permission fiddling. It seems to attempt allowing x11 access but fails.
Reverting to older version seems to fix the problem. The broken version is 0.6.14-2 and the old, working version is 0.6.13-1.
Sorry for this number of comments. I tried it with LXDE as well, with same results. I installed my system with the Xfce spin and my display manager is thus lightdm.
For some reason it seems to work now.
Sorry, the Comment 3 was a mistake. I installed the lastest version, logged out and in again and the problem persists.
I tested this by switching to GDM, and the problem goes away. GDM does use Wayland and starts the X session as the user that logs in. Maybe that's related to the problem.
Sorry if this is improper protocol but I've never used this site before. I'm suffering the same bug here (workaround here works as well) on OpenSUSE Tumbleweed. The reported version is also 0.6.14
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
