Notifications - no longer working in Qubes 4.3 - Debian 13 template - ProtonVPN not minimizing to icon

Hi,

I was looking for info on an issue with Notifications of ProtonVPN app
I did notice a thread about notification errors related to bluetooth - this seems different

Notification is no longer working in QuBes-4.3 and Debian 13 xfce template
it was fine in qubes-4.2 with Debian 12

it is failing with this error:


$ protonvpn-app 
Unrecognized value "gl-disable". Try GDK_DEBUG=help
Unrecognized value "vulkan-disable". Try GDK_DEBUG=help

config of notifications in appvm - same as it was in debian12 :

/usr/share/dbus-1/services/org.freedesktop.Notifications.service

[D-BUS Service]
Name=org.freedesktop.Notifications
Exec=/usr/libexec/notification-daemon

Where should the answer be found, please?
I checked forums on XFCE4, and they gave the same config for notifications.

Thanks,

Protonvpn-gnome-desktop need appindicator package to minimize to tray.

hi @KitsuneNoBaka

thanks for the suggestion, but this package is already installed:

$ sudo apt install gnome-shell-extension-appindicator
gnome-shell-extension-appindicator is already the newest version (59-4).

once started, protonvpn-app will minimise to task-bar
if closed, it will remain in background
if you try to start another instance, the instance running will re-surface
(correct behaviour)

it is the notification that is bugged now

Cheers

p.s.: i did use the correct spelling - minimised

No solution but I just want to validate that I am also experiencing this issue using Fedora 43. I had to rebuild sys-vpn and not enable “start app minimized” in order to have access to the protonvpn app.

Notification is no longer working in QuBes-4.3 and Debian 13 xfce template
it was fine in qubes-4.2 with Debian 12

Not sure if related, but the Profanity XMPP client is also failing to
send notifications, it was working back in QubesOS 4.2, under debian 12
xfce.

Any updates on this?
