XFCE Issue (xfdesktop)

Hi everyone !
I've encountered a problem which I can't handle after 6 months of using Arch :

Every time I login (XFCE + LXDE), my icons disappear, my background is replaced by a gray one and the panels aren't working.
Also, I can't change the background.

If i delete /session and ./config/xfce4 I can make my desktop again.

At the next login I will not have them again.

So, I tried investigating and I think the problem is with xfdesktop.

Output : http://i.imgur.com/xfuN9eF.png

I am waiting for a solution. Thanks !

Hello!

Please do not post screenshot of text output, post the actual text, see this: https://wiki.archlinux.org/index.php/Co … s_and_code

I think you would benefit from reading and following these guides:
- Arch Xfce wiki
- Arch LXDE wiki

Regards
Martin

It is advised to follow the How to post guide when posting on the Arch forum. If one consciously jumps over these elementary steps like reading the wiki and providing necessary information about the problem, one can be regarded as a Help Vampire.

Re: XFCE Issue (xfdesktop)

Strangely, I found out that the problem has to do with conky.

I was editing my conky config, and while it was disabled, the xfdesktop & worked.

After I enabled conky, the wallpaper went back to gray for 3 seconds, and then crashed...

So, let's say it's SOLVED. Thanks !

Re: XFCE Issue (xfdesktop)

After 4-5 boots, the issue is back there w/o conky...
I don't know what to do.

EDIT : I see that the Whiskers icon changed to default. If it helps.

Re: XFCE Issue (xfdesktop)

switch to VT1

export DISPLAY=:0
xwininfo

switch back to VT2, click the "gray area", switch to VT1 once more and see what kind of window that is.
xprop might tell you even more but you'll have to redirect the output (eg. into less)

Re: XFCE Issue (xfdesktop)

I don't know what VT1 or VT2 is, but here is the output of the commands when I click the gray background :

[stefan - ~/c] $ xwininfo

Re: XFCE Issue (xfdesktop)

ctrl+alt+f1, but it's ok - xfdesktop crashed (or quit)
you could run it in gdb to see where and why.

Re: XFCE Issue (xfdesktop)

I am pretty sure that it crashes because of this :

[stefan - ~] $ xfdesktop &
[1] 15238
[stefan - ~] $ xfdesktop: cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: Assertion `!scaled_font->cache_frozen' failed.

Also, here is with gdb :

[stefan - ~] $ gdb xfdesktop &
[1] 15310

As of gdb: don't fork it and you've to "run" the process (from gdb prompt) to get anywhere and then "bt" it ("BackTrace")

Re: XFCE Issue (xfdesktop)

Well...If I delete .config/xfce4 and .config/xfce4-session, it will work only the first boot after....I tried it 3 or 4 times.

Re: XFCE Issue (xfdesktop)

Which Appearance theme are you using an what is your default font? The default font can be found at Settings Manager > Appearance > Fonts but can be overridden, usually in ~/.gtkrc-2.0.

There is a known issue with murrine-based themes and bitmap fonts that causes this issue and that exact error message.

Appearance theme : Numix
Default font : Terminal 10

Numix is a murrine-based theme. Change the font back to the default "Sans 10" and see if the problem persists.
