xfwm4 issue

frpatte · 2016-09-17 12:36:34

Bonjour,

I am facing a problem with xfwm4: sometimes, when I login, xfwm4 is not active and I have to start it "by hand".

In .xsession-errors file I have this message:

(xfce4-session:5124): xfce4-session-WARNING **: gpg-agent returned no PID in the variables
xfwm4-Message: Another Window Manager (unknown) is already running on screen :0.0
xfwm4-Message: To replace the current window manager, try "--replace"

(even if the window manager succeeded to start)

What does it mean? How to get an every time working session?

I have only xfce4 installed on this machine, and no other window manager....

Thank you for helping.

Is your system trying to start xfwm4 twice?
Do you have it listed in your Application Startup (Settings Manager > Session and Startup > Application Autostart).

Try clearing your saved sessions cache (Settings Manager > Session and Startup > Session > Clear saved sessions).

There are only:

xfce4-panel
xfwm4
Xfsettingsd
xfdesktop

The .config/autostart directory has only one file: xfce4-settings-helper-autostart.desktop
which contains:

[Desktop Entry]
Hidden=false

No change after that.

Which distro and which version of Xfce are you running?

How are you starting Xfce? Display manager or via command line?

Can you remove "xfce4-panel", "xfwm4", and "xfdesktop" from your Settings Manager > Session and Startup > Application Autostart list and clear your session cache one more time. Then log out and back in again and test.

If it's still a problem, post back your ~/.xsession-errors log file.

So I had to start xfwm4 and xfce4-panel from cli.... and message is still there.

There must be another window manager starting. What do the following commands return:

ls ~/.config/autostart

ls /etc/xdg/autostart

Also try clearing your sessions cache like this:
- log out
- from the log in screen, press Ctrl+Alt+F1
- log in to the text console
- run the following commands:

cd .cache
rm -rf sessions

- return to the gui login screen by pressing Ctrl+Alt+F7
- login.

Ok this seems to fix the problem: no more message about an unknown window manager in .xsession-errors

Thank you. I let you know if xfwm4 fails to start again at login (this behaviour is uncertain!)
