GUI freezes during right-click Thunar operations

[Toz]

@Sangvin, Can you please confirm the exact nature of your problem? Is it right-click on thunar window and thunar freezes?

Can you post back the contents of .xession-errors right after a thunar freeze (I'm not sure if the log you posted was right after a thunar freeze).

When thunar freezes, does the rest of your desktop still work?

And finally, have you tried thunar with a different login to see if its specific to your login or the whole system?

Sorry, i should have explained better. When i log into xubuntu right clicking on the desktop doesn't do anything (mouse is working i've checked and the main menu in xfce panel works) sometimes it shows the menu but with a delay of a few seconds, .xsession-errors reports

 ** (xfdesktop:1379): CRITICAL **: Unable to get keyboard/mouse grab. Unable to pop up menu

(xfdesktop:1379): LIBDBUSMENU-GLIB-CRITICAL **: dbusmenu_server_set_root: assertion `DBUSMENU_IS_MENUITEM(root)' failed

(xfdesktop:1379): LIBDBUSMENU-GLIB-CRITICAL **: dbusmenu_server_set_root: assertion `DBUSMENU_IS_MENUITEM(root)' failed

(xfdesktop:1379): LIBDBUSMENU-GLIB-CRITICAL **: dbusmenu_server_set_root: assertion `DBUSMENU_IS_MENUITEM(root)' failed

(xfdesktop:1379): LIBDBUSMENU-GLIB-CRITICAL **: dbusmenu_server_set_root: assertion `DBUSMENU_IS_MENUITEM(root)' failed

Now when i open thunar it will show as usual but i cannot click anything (folder, files, even the thunar main menu does not respond) also in htop i see that thunar uses 80~100% one of my cpu cores and it will stay like this unless i kill it. I can move the thunar window around and it will draw correcly, also the min,max and close buttons work when clicked.

Yes everything works except the menu.

have you tried thunar with a different login to see if its specific to your login or the whole system?

I have tried it with a new user and everything works as expected.

So what now, should i replace the .config from the new user to the old, i would really like to keep my desktop as it is though.

If right-click on the desktop isn't working, then check that xfdesktop is running (ps -ef | grep xfdesktop | grep -v grep). If not, then Alt+F2 and xfdesktop --reload to get it going again. xfdesktop controls the desktop and the menu/mouse control on the desktop.

...sometimes it shows the menu but with a delay of a few seconds

This is normal, at least for me. I've never looked for a setting to remove the delay. I find that going directly to the menu on the panel is speedier

, .xsession-errors reports

 ** (xfdesktop:1379): CRITICAL **: Unable to get keyboard/mouse grab. Unable to pop up menu

This is an interesting error message. Here is a link to a similar problem on a fedora install: https://bugzilla.redhat.com/show_bug.cgi?id=717912. Whats interesting here, is that the user has a large number of images in one of the xfce-specified directories, and that is causing all the hassle. Do you have a large number of images in one of your directories? Have a look at ~/.config/user-dirs.dirs to see which directories xfce identifies as system-specific directories. If you have a large number of images in one of thos directories, try moving them elsewhere.

Also, are you cycling your background images (using "Image List" in the desktop properties)? And if so, are there a large number of images in that list?

Now when i open thunar it will show as usual but i cannot click anything (folder, files, even the thunar main menu does not respond) also in htop i see that thunar uses 80~100% one of my cpu cores and it will stay like this unless i kill it. I can move the thunar window around and it will draw correcly, also the min,max and close buttons work when clicked.

Sure sounds like the bug mentioned above.

I have tried it with a new user and everything works as expected.

So it is related to your profile.

So what now, should i replace the .config from the new user to the old, i would really like to keep my desktop as it is though.

Lets try to figure out whats causing it first, before we resort to more drastic measures.

[Sangvin]

Yes, that was the problem.
I didn't have that many images in the folder (about 28 ) but they were gigantic some were 5000x5000 or even 10000x10000 mostly all were png's and all were shown in the desktop background list. Moving them to another folder made everything work again.

Thank you very much Toz, you have saved my Xubuntu

Glad to hear you found the problem. If you don't mind, can you mark this thread as solved using the Thread Tools link above?

You might also consider adding your name and information to the xfce bug report at: https://bugzilla.xfce.org/show_bug.cgi?id=7834 so that this bug can get fixed for future users.

I added the report but i cannot mark the thread as solved since i'm not the one who started it, maybe a forum mod could do that.

this has been bugging me for a while too. i finally got around to digging into why. if you strace the xfdesktop process, you'll notice that very soon after you right click on the desktop it starts reading in a huge number of svg icon files. if you have a drive that isn't blazingly fast or that is busy doing other things this will take a second or two.

you can disable this behavior by running xfdesktop-settings. in the Menus tab, uncheck "Show application icons in menu" or "Show applications menu on desktop right click". after you do so, things should be very quick again.

i'd argue that this should be the default for xubuntu (perhaps both off, since the application menu is accessible by default from the panel - but at least the "no icons" one)

hi,
it seems i'm the new one to have this kind of (erratic) problem with thunar. i' ve a freshly installed xubuntu 11.10 with an encrypted home on a brand new 64bit CPU. my freeze is the same as the one described by the original message (by mister_playboy), although it seems that thunar try to load a huge amount of data as for sangvin (CPU at 99~101% !). here is the thing:
the right-click menu in thunar is fine except for the "create document" submenu which doesn't popup properly (just a very small rectangle appears), the CPU races and all the desktop freezes. the mouse moves but clicking has no action, alt-ctl-F1 works, kill -9 and back to GUI brings all back to normal. .xsession-errors says :

(thunar:3739): Gdk-CRITICAL **: IA__gdk_window_get_window_type: assertion `GDK_IS_WINDOW (window)' failed

i've tried also the "right-click on the desktop / create from template / empty file" and this one works fine (no freeze, nothing in.xsession-errors), but interestingly opening leafpad and saving the new file gives (no freeze):

(leafpad:3829): Gtk-WARNING **: Unable to retrieve the file info for `file:///home/mmanu/test': Error stating file '/home/mmanu/test': No such file or directory

cat /var/log/syslog gives nothing after the crash

i've reported the bug at the existing (old and closed) entry at https://bugs.launchpad.net/ubuntu/+s...ar/+bug/714349

i want to note also that the seemingly related bug (same name + "thinking a directory was a file") at https://bugs.launchpad.net/ubuntu/+s...ar/+bug/852410 is affecting me too (no freeze there), although i can't reproduce it at will: the problem appeared after a logout/login with either the folder of my external HD, which became an unopenable file in thunar (with its path as a name) or with the "network" entry in the shortcut side pane. this weird behavior of thunar was one of the reason of my downgrade to 11.10, when i tried the 12.04 alpha a couple of days ago (with some problem to create/access to an external HD encrypted partition, which are by the way ok with 11.10). i'm very disappointed to find it back here!

for information, i've changed the places' names in .config/user-dirs.dirs, i've all my files in these folders (50G) and no image list for my background...

i checked on my asus T91MT xubuntu lucid LTS (not encrypted, modified user-dirs.dirs) and the same .xsession-error occurs

(thunar:1343): Gdk-CRITICAL **: IA__gdk_window_get_window_type: assertion `GDK_IS_WINDOW (window)' failed

when opening the "Create Document" submenu, but without the freeze.

i redid (see previous post) the leafpad test also with my lucid eeepc (open mousepad & create/save an empty file) but there no errors message in xsession-errors.

[mmanu]

i tried it on the guest account and here is the result:
no freeze, but the same .xsession-error just after the right-click.
the "create document" submenu is fine and the error appears not to be related to its opening but just to the right-click menu opening.
i retried with my session & indeed, the right-click suffices to procude the error and the freeze doesn't occur. then i place my mouse on "create document", the GUI freezes without additional error message
