Hello. A newbie to xfce. I can see I'm going to have many questions.

Hello xfce people.  Just found this forum.

Not a newbie to technology.  At the moment I'm trying to figure out this little lot that's thrown when xcfe is operating under Windows 10's WSL2 with X410 as the xserver.  It all works.  I sort of look at the console and and go.....   Ugh?   Then partially throw my hands up.

As in . . . .

C:\Users\myron>start /B x410.exe /desktop

C:\Users\myron>ubuntu.exe run "if [ -z \"$(pidof xfce4-session)\" ]; then export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0; echo 'Starting XFCE4 in bottle ...'; genie -c xfce4-session; echo 'Stopping processes ...'; pkill '(gpg|ssh)-agent'; fi;"

Re: Hello. A newbie to xfce. I can see I'm going to have many questions.

Hello and welcome.

when xcfe Xfce is operating under Windows 10's WSL2 with X410 as the xserver.

Disclaimer: no expertise in this setup. Can only help identify source of messages below. 

C:\Users\myron>ubuntu.exe run "if [ -z \"$(pidof xfce4-session)\" ]; then export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0; echo 'Starting XFCE4 in bottle ...'; genie -c xfce4-session; echo 'Stopping processes ...'; pkill '(gpg|ssh)-agent'; fi;"

This is the command being run internally. It's being echo'd into the log file.

xfce4-session: GNOME compatibility is enabled and gnome-keyring-daemon is found on the system. Skipping gpg/ssh-agent startup.

Informational message indicating state of gnome-keyring-daemon startup.

env: ‘kdeinit4’: No such file or directory
Cannot find '.setLaunchEnv' in object /KLauncher at org.kde.klauncher

These belong to KDE. Did you install, at some point, KDE on this system? If so, there are remnants left behind.

xfwm4 can't start because another window manager is managing the system. Race condition or maybe a KDE leftover? Which one is actually running now:

ps -ef | grep -E 'xfwm4|kwin'

** (xfce4-clipman:716): WARNING **: 16:45:28.304: Unable to register GApplication: An object is already exported for the interface org.gtk.Application at /org/xfce/clipman

(xfce4-clipman:716): GLib-GIO-CRITICAL **: 16:45:28.304: g_application_get_is_remote: assertion 'application->priv->is_registered' failed

Looks like xfce4-clipman is running both as an application in autostart and as a panel plugin. You can only run it one way. It looks like this message is telling you that that plugin is already running and it can't run the executable. Safe to ignore, or remove xfce4-clipman entry from autostart (or remove panel plugin).

** (xiccd:732): WARNING **: 16:45:28.639: EDID is empty

xiccd (color management) can't find monitor information. Maybe a by-product of the way you are running it?

Connection failure: Connection refused
pa_context_connect() failed: Connection refused

Pulseaudio error messages. Can't connect to device. Does sound work?

(xfce4-panel:645): garcon-CRITICAL **: 16:45:29.608: garcon_gtk_menu_get_desktop_actions_menu: assertion 'actions != NULL' failed

(xfce4-panel:645): garcon-CRITICAL **: 16:45:30.111: garcon_gtk_menu_get_desktop_actions_menu: assertion 'actions != NULL' failed

Something wrong with connecting the menu to the desktop. What is managing your desktop? Is xfdesktop running?

(wrapper-2.0:755): GLib-GIO-CRITICAL **: 16:45:30.255: g_file_new_for_path: assertion 'path != NULL' failed

(wrapper-2.0:755): GLib-GIO-CRITICAL **: 16:45:30.255: g_file_monitor_file: assertion 'G_IS_FILE (file)' failed

"wrapper" refers to a panel plugin. One of them is issuing this error. The number "755" refers to the pid of the offending panel plugin.

(wrapper-2.0:755): GLib-GObject-WARNING **: 16:45:30.256: invalid (NULL) pointer instance

(wrapper-2.0:755): GLib-GObject-CRITICAL **: 16:45:30.256: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

(wrapper-2.0:755): Gtk-WARNING **: 16:45:31.200: Negative content width -3 (allocation 1, extents 2x2) while allocating gadget (node button, owner GtkToggleButton)

More messages related to the same panel plugin. Some of these warnings are just theme-related warnings and can be ignored.

Tracker-Message: 16:45:31.330: Set scheduler policy to SCHED_IDLE
Tracker-Message: 16:45:31.331: Setting priority nice level to 19

Looks like tracker-miners is installed and running - these are informational messages.

(wrapper-2.0:754): Gtk-WARNING **: 16:45:32.645: Negative content width -3 (allocation 1, extents 2x2) while allocating gadget (node button, owner PulseaudioButton)

The pulseaudio plugin theme-related messages. Can be ignored.

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-myron'

This is a QT/KDE related message.

Tracker-Message: 16:45:33.573: Set scheduler policy to SCHED_IDLE
Tracker-Message: 16:45:33.573: Setting priority nice level to 19

tracker-miners repeating message

This is a KDE-related app. There is an entry in your Applications startups (~/.config/autostart or Session and Startup > Application Autostart) and this program no longer exists on your system. You should remove/delete this autostart entry.

** (xfce4-screensaver:729): WARNING **: 16:45:35.225: screensaver already running in this session

xfce4-screensaver is attempting to start but finding itself already running. Might be a good idea to delete the contents of ~/.cache/sessions.

** (xiccd:732): CRITICAL **: 16:45:35.277: failed to create colord device: failed to obtain org.freedesktop.color-manager.create-device auth

You don't have permissions to create a color management device. Search google for this error and you'll find potential workarounds and fixes.

All good fun.  :-)

It always is. Hope this helps.

Re: Hello. A newbie to xfce. I can see I'm going to have many questions.

Thank-you for the reply and the analysis.

Hmmm....  I may have tried KDE.  So, how to I check and strip any remnants of KDE out of the installation?

Re: Hello. A newbie to xfce. I can see I'm going to have many questions.

Review your package manager logs from around the time you installed KDE and ensure that all of those packages are removed. You may need to review each one individually to ensure it is KDE related.
