CSD appears in XFCE windows despite `unset GTK_CSD`

[Flashwalker]

Don't know bug or feature CSD panel appears in XFCE windows despite unset GTK_CSD with ppa:lah7/gtk3-classic https://github.com/lah7/gtk3-classic/discussions/92

If purge the ppa and packages:

gir1.2-gtk-3.0 gtk-update-icon-cache libgail-3-0 libgtk-3-0 libgtk-3-bin libgtk-3-common libgtk-3-dev

That CSD panel in Xfce windows has disappeared because it now uses (or does not use) its own window border. So, now CSD substitutes the window manager's window border (close, minimize, maximize buttons are just hidden by custom gtk.css)

What distro/release are you using?

If I recall, some CSD patches were excluded for the Ubuntu packages because that "double controls" issue was a problem under Ubuntu MATE.

What distro/release are you using?

I'm using Ubuntu 22.04

I think it depends a lot on the GTK theme. For example, for me on Xfce4 it looks like this

And give it a try with this theme https://github.com/robson-66/DarkCold

This first screenshot of mine was made on a compiz session, and this is what it looks like on an xfwm4 session

There is a big difference between your screenshot and mine.

I'm just using packages from ppa

[lah7]

I believe it's a problem specific to the Ubuntu package. I'll need to review it and repackage when I get time.

@robson-66 I'm guessing you're not using Ubuntu 22.04? (Likely, "building" on Arch?)

[robson-66]

Yes, I'm on Arch Linux.

I think you might need to set /Gtk/DialogsUseHeader to false: https://gitlab.xfce.org/xfce/libxfce4ui/-/issues/14

I'm allredy have

$ xfconf-query -c xsettings -p /Gtk/DialogsUseHeader
false

it's not related

I wondered if this is still an issue and yes, I can see it on Ubuntu 22.04 (XFCE 4.16), but not under Arch Linux (XFCE 4.18).

A quick web search revealed articles that XFCE 4.16 switched to CSD by default. Later, I found XFCE's blog post for "Xfce 4.18 released" (December 15, 2022) which implies that they went back to server side decorations. 👍🏼

All header bars of Xfce Windows/Dialogs by default will be drawn by the window manager now (Xfwm4).

In terms of gtk3-classic, I don't see what we can do. Our patches make the CSD act more like a toolbar (like removing the center window title & right window buttons) but these XFCE apps still have an item (or two) in the CSD area, like the search button.

In the original post, that screenshot shows a very thick CSD, so that might be theme related.

Left = Normal | Right = Patched

The better solution is to upgrade XFCE, but that might not be feasible under Ubuntu 22.04.

Yeah, it's ok now with 4.18
