[SOLVED] GTK3 applications fail to start after logging in

PurpleViolin75 · 2024-08-05 10:14:52

Hello,

Right after logging into my user account, `thunar` and `evolution` fail to start and report the following errors:

$ thunar

(thunar:1693): Gdk-WARNING **: 11:24:03.311: The program 'thunar' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 219 error_code 8 request_code 138 (XFIXES) minor_code 2)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

$ evolution

(evolution:1748): Gtk-WARNING **: 11:24:07.682: Creating a portal monitor failed: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “org.freedesktop.portal.Inhibit” on object at path /org/freedesktop/portal/desktop

(evolution:1748): Gdk-WARNING **: 11:24:07.704: The program 'evolution' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 159 error_code 8 request_code 138 (XFIXES) minor_code 2)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

The strange thing is that this issue disappears on its own (!) after 2min - 30min. Both applications then start cleanly and without reporting any issues. However, if I log out and log back in again, the problem reappears. If I log into multiple users in parallel, the issue appears for each user independently (I have to wait everywhere).

I tried to debug it, but that didn't work either:

GDK_SYNCHRONIZE=1 gdb thunar

(gdb) break gdk_x_error
Function "gdk_x_error" not defined.

There are suggestions on the internet to set various environment variables, like `WEBKIT_DISABLE_COMPOSITING_MODE=1` and `XLIB_SKIP_ARGB_VISUALS=1`, but these didn't help. The only thing that helps is waiting.

I made a full system upgrade today, but the issue still persists.

Any ideas what might be going on here?

Make sure to see the last link below (2nd blue note about what to include at least) but I don't think that's the cause and neither is a transient hostname…

Since xfixes seems a constant and it mostly deals w/ cursors and embedding windows - do affected clients add a systray?
Is this a multihead setup?
Do you use the adwaita cursor theme? Try https://archlinux.org/packages/extra/an … la-dmz-aa/ instead (it's visually the same but not intentionally broken)

Not sure what you mean here. This post? I don't see that list there.

Yes, they all do. I use the Status Tray Plugin from the XFCE4 Panel.

Is this a multihead setup?

Not a multihead -- I only use my laptop's monitor.

Do you use the adwaita cursor theme?

I don't think so, but I'm not quite sure. I think that I'm using some default X cursors, but it may be that XFCE is interfering here.

My regular setup:

gnome-icon-theme from AUR (needed it for dunst icons)
adwaita-icon-theme (as dependency)
adwaita-cursors (as dependency)
xfce4-appearance-settings are set to the Adwaita theme
In my `.xinitrc`, the only cursor-related command is `xsetroot -cursor_name left_ptr`

What I tested:

Tried to remove gnome-icon-theme. No changes.
Tried to set appearance settings to High Contrast. No changes.
I can't uninstall adwaita-icon-theme or adwaita-cursors, since these are required by gtk3; then, I wouldn't be able to test gtk3 apps.

----

I tried to start with a minimal .xinitrc

if [ -d /etc/X11/xinit/xinitrc.d ]; then
  for f in /etc/X11/xinit/xinitrc.d/*; do
    [ -x "$f" ] && . "$f"
  done
  unset f
fi

# urxvt daemon
urxvtd &

# start xmonad
exec xmonad

The issue still appeared!

----

Maybe it would help to properly debug the gtk apps, as suggested in the error message. I'm not sure what breakpoint to set, though.

----

What is some config that's related to X, but that changes some time after logging into the user? As I mentioned, the weird thing is that it consistently starts working after a while.

seth · 2024-08-06 14:25:34

Not sure what you mean here

http://wiki.archlinux.org/title/Xinit#xinitrc - but you have the relevant segment in your minimal script (and I didn't really think it could be the issue here anyway)

You don't have to set any breakpoints, just run the client in gdb, let it crash and draw a backtrace. But

Yes, they all do. I use the Status Tray Plugin from the XFCE4 Panel.

is a HUGE red flag, can you disable the systray icon for any of the clients and see whether the issue remains?
Does https://archlinux.org/packages/extra/x86_64/sbxkb/ work?

I could imagine issues w/ 24 ./. 32 drawables, but that doesn't fit the "goes away after a while" part.
What happens if you remove the systray from the panel?

PurpleViolin75 · 2024-08-09 12:47:33

Uninstall xfce4 / Status Tray Plugin

I ran `pacman -R xfce4{,-goodies}; pacman -S thunar evolution xfce4-panel` just to be absolutely sure that xfce doesn't interfere. Same result though.

I also removed the Status Tray Plugin through the settings of the Panel. Same result.

xfce4-panel crashes now

After uninstalling and reinstalling the xfce4 packages, the panel itself started to crash: When I try to open the Panel Preferences, it crashes with a similar error. This crashing behavior also goes away after a while (together with the other two).

Here are all three errors for reference:

$ thunar

(thunar:1324): Gdk-WARNING **: 14:18:31.541: The program 'thunar' received an X Window System error.

It's always `serial $n error_code 8 request_code 138 (XFIXES) minor_code 2`

sbxkb

I installed `sbxkb` and started it. It showed up in my systray and I could click on it to change the keyboard layout. Zero issues.

Other trials

Don't start `megasync` on startup. No difference.

Disabled the GTK3 config (`.config/gtk-3.0`). No changes.

Another system upgrade. No changes.

Debugging it

Tried to debug it. It says "no stack". Probably because it's just a process without debug info. Here's the log:

I checked out the source code here: https://gitlab.gnome.org/GNOME/gtk. The error seems to come from `gdk/x11/gdkdisplay-x11.c`, namely

void
_gdk_x11_display_error_event (GdkDisplay  *display,
                              XErrorEvent *error)

But when trying to set a breakpoint at this function, it says

(gdb) break _gdk_x11_display_error_event
No symbol table is loaded.  Use the "file" command.
Make breakpoint pending on future shared library load? (y or [n]) Quit

Hopefully I can avoid compiling that thing myself -- the README looks quite involved.

gtk3-demo

I installed this from the `gtk3-demos` package

This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 347 error_code 8 request_code 138 (XFIXES) minor_code 2)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Then, the debugging:

$ GDK_SYNCHRONIZE=1 gdb gtk3-demo

About the debuginfo: gdb seems to load this automatically (failed to read it properly, my bad lol)

After the `New Thread` messages, the whole X session freezes. No mouse and keyboard interaction, even my clock freezes. I had to kill the `gtk3-demo` process via another VC. At least a bt is still produced.

gtk-demo

This is the old gtk2 demo. Also doesn't work:

$ gtk-demo // same with gtk-demo --sync
The program 'gtk-demo' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 207 error_code 8 request_code 138 minor_code 2)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

However, whenever I run it in debug mode, it does work. I tried 4-5 times, I never got it not to work so that I could debug it. Just a fluke?

After it runs in debug mode, it also runs when started regularly AND all of the other programs also start running. I now at least have a really weird workaround if I really need to check my email...

Same story as gtk3-demo: After running it, the whole X session froze (right after the `New Thread` messages). Mouse doesn't move, keyboard doesn't work. I then killed the process with SIGKILL via another VC. Fortunately, the backtrace still worked.

Still need to look into the source files.

Did you run any partial updates?

PurpleViolin75 · 2024-08-09 15:45:44

This seems relevant, especially the comments:

static int handle_error(Display *dpy, xError *err, Bool in_XReply)
{
	_XExtension *ext;
	int ret_code;
	/* Oddly, Xlib only allows extensions to suppress errors when
	 * those errors were seen by _XReply. */
	if(in_XReply)
		/*
		 * we better see if there is an extension who may
		 * want to suppress the error.
		 */
		for(ext = dpy->ext_procs; ext; ext = ext->next)
			if(ext->error && (*ext->error)(dpy, err, &ext->codes, &ret_code))
				return ret_code;
	_XError(dpy, err);
	return 0;
}

From the X11 source, `src/xcb_io.c:197`

PurpleViolin75 · 2024-08-09 15:49:20

No partial updates that I'm aware of. I did a full system upgrade just today again.

gtk commits suicide on X11 "errors", that's dumb but normal - the question is why you're getting an error from xfixes itfp and the corrupted stack is worrysome.

Edit:

I bet your left and right arm that's the problem…

HELL YES! This is the cause!

`pacman -R xorg-server-git; pacman -S xorg-server` fixes it.

The problem now: The reason I installed the git version is because of massive tearing that I experience with `xorg-server` (to the point where your eyes hurt when scrolling through long text like this thread). I tried to switch from the iGPU to my Nvidia card, but this came with a bunch of other issues. After multiple days, this was the only really acceptable solution to my graphics problem...

Is there some kind of workaround to this? Basically, find a way to get to the "everything works" state right after logging in.

Nevermind, I found a "workaround": just install the newest damn version!

I ran `yay -S xorg-server-git` and asked it to cleanBuild it. Now, I have no tearing and all of my applications start immediately. Wonderful!

Lesson learned: full system upgrade also includes the AUR...

On a personal note, that was some fantastic help, seth. I wouldn't have figured it without you. Kudos!
