xfwm4 crash

debugpoint.com · 2021-07-18 09:55:04

Hi
I am not sure what happened, but my XFCE desktop lost the title bar from all windows. Window manager is not opening.

See here:

System conf:
Arch Linux (latest)
Xfce 4.16
lightdm

Any idea?

I tried re-installing xfwm4 but same result.

Hello and welcome.

xfwm4 --replace

...should restart it.

~/.xession-errors should give some hints as to why it crashed.

If its not coming back on a fresh login, delete the contents of ~/.cache/sessions before you log to Xfce.

Deleted the contents of cache/sessions -> same problem
tried replace switch -> same problem

Here is the error file from session, it says this is a bug!

xfwm4 is crashing:

(xfwm4:534): Gdk-ERROR **: 00:15:33.300: The program 'xfwm4' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.

   backtrace from your debugger if you break on the gdk_x_error() function.)

What video card and video driver do you have?

Try running xfwm4 with GDK_SYNCHRONIZE:

GDK_SYNCHRONIZE=1 xfwm4

...then look at the coredump wiki article on how to get a backtrace. You may need to build xfwm4 with debug enabled to get to the root of the problem.
