I upgraded 28 to 29.
Upgrading to 30, at startup, I have this NEW automatic window that I have to manually close.
“Because the panel is running in kiosk mode, you are not allowed to make changes to the panel configuration as a regular user”.
I only have one regular user and SU.
I searched about Fedora Kiosk mode without success.
I am not using xfce so I will try provide some tips than i did google and maybe help you.
A) Option 1 (remove file xfce4-panel.xml): Use this commands
rm .config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml
rm -r .cache/*
reboot
B) Option 2 (disable save sessions):
https://wiki.archlinux.org/index.php/Xfce#Disable_saved_sessions
C) Option 3 (Add your user to the kiosk mode if your user is not present):
https://wiki.xfce.org/howto/kiosk_mode
I am sorry than i can not provide more help than the one you can find on internet. You can just wait for some xfce user what know a bit more about it.
Regards.
Option 1
IMPORTANT: First I made a copy of the “xfce4-panel.xml” file called here the OLD!
I did:
rm xfce4-panel.xml file
But did not:
rm -r .cache/*
Result startup:
A new xfce4-panel.xml file is created, the default DOCK appeared and stays permanent; The dock I installed within Ferora 28-30 gets on top of the default.
And the panel does not keep my personal settings-options like the keyboard layout etc.
Warning window does not show;
The “Panel preferences window” still opens and I have to close it manualy.
Restart with OLD xfce4-panel.xml file:
Warning window does not show! (?)
The “Panel preferences window” still opens and I have to close it manually.
I should have mentioned on my first posting:
This window ERROR:
“Failed to show the preferences dialog
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown:
The name is not activatable”
Note: I upgraded 28-29-29-30 without making any modifications. And the upgrades were done without using Fedora 29!
If you do a backup of your xfce-panel.xml why didn’t you do a backup of your cache?? I clean cache every week more or less there is nothing bad about clean cache. Did you know that in your cache is also sessions from xfce than you need clean but you did skip it.
Do a backup of all than you need do but please clean your cache like indicated.
rm .config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml
rm -r .cache/*
reboot
About your other issue try firs do the option A like indicated, after run a sudo dnf --refresh --allowerasing upgrade. If it persist look if this bug can be related https://bugzilla.redhat.com/show_bug.cgi?id=1704299 and if it does pls report the problem.
Regards.
One startup after the next, those error windows alternate:
1- “Panel preferences window”
2- “GDBus.Error:org…”
They do not appear at the same startup.
I did some research about backup cache…
I do not know how to do it and the consequences of the command: rm -r .cache/*
And I do not know why by upgrading, I got those errors.
Suggestion NOT WORKING! And you loose your personnal setups.
