I am running Centos 5.5 X86_64 and recently after updating my server, I am having problem loading gnome. When the server boots, and begins to bring up the login screen theme, I get an error that states "Could not recognize the image file format for /usr/share/gdm/themes/TreeFlower/background.png"

I am able to login after clicking ok to this message, and using the "simplistic" login manager. But when the users desktop loads, there are several errors pertaining to "unsupported image format" and none of the icons are displaying correctly. They are just the default "curvy page" icon for an unassociated file type. Some of the icons do not even show up at all.

Another thing I noticed wierd is that when I try to view a png, nothing happens. When I try to open one using gimp, I get an "unsupported file type" error.

When I tried to click on the "add/remove software" button I get prompted for root pass, but nothing happens. So, I tried launching pirut from CLI, and I received the following error:


Can anyone give me some suggestions? Is is possible a GTK2 update killed png associations? Is something messed up with libpng?

Is libpng installed? If not, then install it.

Yeah, libpng is indeed installed. I have even tried yum reinstall and cleaning up the db but still same problem. here is the paths libpng is located in.... do these seem correct?

I don't have libpng-devel installed, just libpng. Not sure why that should matter. I'm running Fedora Rawhide with LXDE and Compiz - no problems with using a png file as the background.

Im still drawing a blank on this one. I am not sure where to go. Is there a way to reset the mimetypes or something?

??
what did you do ???
just a standard
if so look at the yum log and see what was installed in that last round
/var/log/yum.log

5.5 64 bit works fine for me
it looks like you have the std libpng 12 ( and the 11.b ) and do not have libpng14 ( do not install that (png14) unless you KNOW how to work around it . )

if this was just a update and NOT -- NOT-- an upgrade from 5.4
reinstalling png should fix it
there will be a bunch

if an upgrade from 5.4 then it is something different


PS the ALPHA TESTING of fedora 15( rawhide is the NEXT fedora ) is using libpng14 and not the stable libpng12

Checked the yum logs, noticed the following around the same time the problems occured:

I am using DirectAdmin for web control panel and Vhosts... I think I installs libpng in /usr/local by default for its custombuild, but I am still researching that. Would be nice to "roll back" those libpng updates from the 28th as seen above, but there are alot of dependancies for libpng.

I did do just a plain yum update and it picked up the new libnpng packages as shown above. I also tried a yum reinstall *png* and still have the issue. It has got to be related to the paths that Directadmin and Centos repos use when they install libpng. I just cant figure out how to get it resolved.

if it worked then did not it is not the file paths
unless you edited the system $PATH in /etc/profile

is there a error logged in boot.log, xorg.0.log , or messages

one thing ? maybe
there was a python update in nov.
cent uses python for a bunch of things including login and root password in the gui
and "pirut" is giving you a python error
try
this can be done in single user text only boot

Nothing in the xorg log or boot.log. I have already tried yum cleanall and updatedb.

The path I was referring was the path the the Centos repos and the Directadmin custombuild installed the libraries too. Not the $PATH...sorry for the confusion on that one.

what repos are installed and turned on
the rpmforge(.rf) has some that DO NOT mix with centOS-plus
and therefore needs "prioritys" and possibly "protect base" yum plugins installed AND SET UP
http://wiki.centos.org/AdditionalResources/Repositories
that outputs a list of all that are installed and on or off

I have them added, but they are disabled. I have only enabled them to grab one package a few months back, then I promptly disabled them after installing the package.

HI

I got exactly the same prob when I updated centos
I also use Directadmin

look at this when I try to start X

I try to uninstall libpng and reinstall it ,clean libpng from /usr/local/lib/ nothing works!!!
actually the strange things is that there is libpng files in /usr/local/lib and /usr/lib/
by default when we compile libpng , it is getting installed in /usr/local/lib , however , the centos package of libpng is getting installed in /usr/lib/
the version of centos is 1.2.10 and the version of custumbuild is 1.2.44

I just try to understand, but actually I did nothing special, I just updated Centos via yum!

a bit a help will be appreciated
it s difficult to find some fix trough Google and I guess a lot of people face the same issue

thanks a lot!!!!

"actually the strange things is that there is libpng files in /usr/local/lib"
---
not so strange i take it you DID NOT read ./configure --help for png ??
it states that /usr/local IS THE DEFAULT
YOU need to add " --prefix=/usr " to the config line


BUT BE 100% sure you use a DIFFERENT NAME than the rpm for png that is installed

-------- edit-----------
seeing as you are both using "directadmin " they must be building a incompatible version of libpng

i would suggest that you uninstall ALL directadmin /usr/local *png programs that "directadmin" installed and ONLY use the cent-update repo for png


the /usr/local folder IS NOT A rhel/centos default folder and is - in all likelyhood-- NOT in the system path in /etc/profile

I removed all files that a manual package or directadmin has installed , and reinstall the rpm package via yum (yum install libpng).
I rebooted but nothing solved...

How can I make a diagnostic to identify where is the real prob?

thanks a lot

it is looking like a "DirectAdmin" problem
that is installing or doing something that is making libpng incompatible with what gdm needs
it is also very very odd that there is no error massage in the boot.log or any other log

i have no issues with gdm on my cent5.5 64 bit install - and i DO NOT use "DirectAdmin"

by chance do you also have KDE installed ? on centos 5.4 and 5.5 ( on an old machine) i used KDM to boot the system into Gnome

At this time i am at a loss .Have you looked on the DirectAdmin forum on there web site .
