Black backgrounds in panels

ToddAndMargo · 2018-11-13 03:37:32

Hi All,

Fedroa 29
Xfce 4.13

black background on panel icons
https://bugzilla.xfce.org/show_bug.cgi?id=14842

From the bug report, here is a picture of what it looks like:
https://bugzilla.xfce.org/attachment.cgi?id=8084

I tested with an unused profile from Fedora 28 and Xfce 4.12 (now Fedora 29 and Xfce 4.13). Then I added items. And this problem could not be reproduced.

What files are involved, so I can fix them?

Many thanks,
-T

Could be a theme or a graphics card issue.

Which GTK (Appearance) theme are you using?

xfconf-query -c xsettings -p /Net/ThemeName

Give the latest version of the Greybird theme a try.

Also try with the default bulit-in Adwaita theme:

xfconf-query -c xsettings -p /Net/ThemeName -s ""

...in both cases, restart the panel after the change:

xfce4-panel -r

Which video card and driver do you have installed and are you using?

lspci -v | grep -A12 VGA

ToddAndMargo · 2018-11-13 13:38:37

both profiles are using Adwaita

no symptom change under GreyBird or any of the others

hardware is the same on both profiles

$ lspci -v | grep -A12 VGA

Something is wrong in the profile of my user account. I need my configuration of panel 0 and panel 1 or I would just start over with a a new profile.

Do you have any content in ~/.config/gtk-3.0/gtk.css ?

ToddAndMargo · 2018-11-13 23:11:23

Actually, no.

The failing profile:

# ls -al .config/gtk-3.0

Can you post back:

xfconf-query -c xfwm4 -lv

Maybe its a compositing issue. Do you have the compositor enabled (Settings Manager > Window Manager Tweaks > Compositing)?

No. I tried that and everything got a black background

MountainDewManiac · 2018-11-14 06:56:01

Are you, by chance, using a third-party compositor, such as Compton?

No, just stock Xfce. It was originally installed from an Xfce Live USB. Fedora 27 I do believe.

I have two machines doing this by the way.

MountainDewManiac · 2018-11-14 08:59:01

Okay. Some distros are being packaged with multiple ones these days, so I wondered if you might have been using one of the other options, perhaps without being aware of it.

MDM

The compositor is disabled on your system. See this bug report for more information on the issue. Summary: there was a change in gtk3 that no longer re-paints the background of systray applications. More info in the bug report.

What do you mean by this? Try enabling compositing and restarting the computer.

Both panels do this. I need to see the panels. The panels do go normal, if I mouse over them, but his is really annoying when I need to check the time. I also use the panels a lot to switch between programs.

This looks is something different. Look at the panel's Opacity settings on the Appearance tab. Set them both to 100.

What are you using as a compositor? Your last output indicated that it was not the built-in one provided by xfwm4. Is it turned on in this screenshot?

I am not following. I am using whatever I had on Fedora 28, Xfce 4.12 that upgraded to Fedora 29 , Xfce 4.13. How do I install a compositor? Which one do you recommend?

mint4all · 2018-11-16 17:49:22

Greetings!

I apologize for not contributing sooner ... However, i noticed in OP #7 that

/general/snap_to_windows                 0
/general/snap_width                      10
/general/sync_to_vblank                  false
/general/theme                           Default
/general/tile_on_move                    false
/general/title_alignment                 center
/general/title_font                      Sans Bold 9

the window manager's theme is set to "Default". I just checked on 3 of my systems (two with xfce 4.12. & one with xfce 4.13), and the window manager's xfwm4.css (@ ~/.config/xfce4/xfconf/xfce-perchannel-css/) is properly set to *my* choice of theme, not "Default". Note: those are not Fedora-builds.

Perhaps that's because i routinely update the window-manager's "style"-setting (Menu > Settings > Window Manager > Style {tab}) whenever I tweak my "Appearance" theme & icons. After looking over the "Default" theme @ /usr/shere/themes, except for its window-frame bitmaps, this is essentially a theme devoid of any settings governing the WM's compositing-settings. So where else would the WM inherit its requisite settings from? Might this possibly contribute to the panel-visibility problem?

Cheers, m4a

Regarding the faded panel, the last image that you posted showing the faded panel means that you are using a compositor. However, your last "xfconf-query -c xfwm4 -lv" output showed that the built-in one is not being used.

Can you post back the following:

The results of:
```
ps -ef | grep $USER
```

The results of:

xfconf-query -c xfwm4 -p /general/use_compositing

The results of:

xfconf-query -c xfce4-panel -lv | grep opacity

One more image of the faded panel.

Post all results from the same system. Let's confirm the settings and see if another compositor is running.

This image is different from your last one and the built-in compositor (Settings Manager > Window Manager Tweaks > Compositor > Enable display compositing) is disabled.

Run the following commands:

xfconf-query -c xfwm4 -p /general/use_compositing -s true
xfconf-query -c xfce4-panel -p /panels/panel-0/leave-opacity -s 100
xfconf-query -c xfce4-panel -p /panels/panel-1/leave-opacity -s 100

Log out and back in again and post back the results of the following commands and another image:

xfconf-query -c xfwm4 -p /general/use_compositing
xfconf-query -c xfce4-panel -p /panels/panel-0/leave-opacity
xfconf-query -c xfce4-panel -p /panels/panel-1/leave-opacity

Note: please use code tags to enclose output so it is easier to read. I'll fix the one above.

This image is different from your last one and the built-in compositor (Settings Manager > Window Manager Tweaks > Compositor > Enable display compositing) is disabled.
Run the following commands:
xfconf-query -c xfwm4 -p /general/use_compositing -s true
xfconf-query -c xfce4-panel -p /panels/panel-0/leave-opacity -s 100
xfconf-query -c xfce4-panel -p /panels/panel-1/leave-opacity -s 100
Log out and back in again and post back the results of the following commands and another image:
xfconf-query -c xfwm4 -p /general/use_compositing
xfconf-query -c xfce4-panel -p /panels/panel-0/leave-opacity
xfconf-query -c xfce4-panel -p /panels/panel-1/leave-opacity

The problem cleared up without having to log out and back in . I did anyway and it stayed cleared up. Thank you!!!

$ xfconf-query -c xfce4-panel -p /panels/panel-0/leave-opacity
