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;"
Starting XFCE4 in bottle ...

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

Hello and welcome.

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'

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?

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

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

"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.

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

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

This is a QT/KDE related 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.

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

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.
