My System was running absolutely fine. But after firefox continuous crash, I rebooted it to find the following strange problem.

Strange problem :

During booting, the text below the graphical progress bar is not coming.
After booting no login prompt. Only one dialog box (without any text in/over it) containing a button having a tick button. Pressing which no effect. Pressed Cntl+Alt+F2, to get text prompt successsfully. Login and startx. After startx, no text in X only icons appear. No text in the menu after clicking the red-hat button. Mouse right click- no text. Only menu with arrows shown. Tried to opened firefox using gnome-terminal, but it crashed giving some pango warning.

I WAS able to get to the desktop, however any icons or any menu items had no fonts to them. In other words, you could see the icons but there was no description as to what they were. This also included the menu that you access on the taskbar, as well. Even the tool-tip on the taskbar is empty.

Can any body help ?

Have you tried another Desktop environment or logging in as another user?

This may be the reason. Pango is the library through which GTK apps draw text.

Thanks for the suggestions. My KDE is running fine. Used 'switchdesk KDE' command and X worked perfectly. But again while starting firefox the same error came ::

"error while loading shared libraries: /usr/lib/libgtk-x11-2.0.so.0: undefined symbol: pango_find_base_dir"

I want to use GNOME. Can some-body help me to solve the problem. The konqueror is running but many a times crashes while surfing.

I tried to download and install the pango-1.4.1, but it conflicts with present rpm pango-1.4.0-2; and it is also not allowing the remove the rpm pango-1.4.0-2 because of dependencies.

Well... try reinstalling the whole GTK. It should also reinstall pango, cairo and some other libraries.

BTW, this may be related to this bug report:

Are you using latest stable distro version?

KDE works because it and it's apps do not use GTK+ (which uses Pango). They use the Qt toolkit instead.

But Firefox uses GTK+.

I had used "rpm -Uvh --force --nodeps" to upgrade to pango-1.4.1-1, pango-devel-1.4.1-1, gtk2-devel-2.4.14-2.fc2, and gtk2-2.4.14-2.fc2.

But while updating the gtk2 package, the rpm package manager shows the following thing --

g_module_open() failed for /usr/lib/gtk-2.0/2.4.0/loaders/svg_loader.so: /usr/lib/libgtk-x11-2.0.so.0: undefined symbol: pango_find_base_dir

Although the package was updated. But the problem remains the same. What should I try to upgrade now ?

It seems I am lost some-where. All the things were running fine earlier with the old versions. I don't remember what things I had changed/modified.

I am seeming the function "pango_find_base_dir" in the file "/usr/include/pango-1.0/pango/pango-types.h". Then why the library "/usr/lib/libgtk-x11-2.0.so" is saying it as undefined symbol ?

This symbol is undefined in libpango-1.0.so or something like.
I haven't found this symbol in /usr/lib/*pango* on my system, so it seems to be obsolete, so your problem is too old libgtk-x11-2.0.so version. Maybe try installing some older version of pango. Or ask on your distro-specific forum.

Hello,

Thanks for the replies and trying to help me. I was stuck at that point. So what I did; reinstall the whole OS again. And get rid of the problem.
I know the OS is old, but so is my machine.

Thanks and Regards,
