Panel application fails at startup.

I've installed RH 7.1 on my box and I ran into the following problem.

When I boot up and login in Gnome Panel application fails. First time it happened after a couple of weeks. After I rebooted the box one day Panel application failed at startup. The system removed it from boot sequence and after next boot Window Manager failed thus rendering system useless.
I reinstalled everything and it's been working for about 4 weeks and the same thing happened again.
Yesterday I reinstalled everything again and when I tried to login for the first time Panel crashed.

Any ideas?

I'm trying to run RH 7.1 on AMD K-2 /450 with 64 MB RAM and 2 NIC cards.

can you open a terminal and run a panel in that? should get more info from it that way, if it crashes...

Strangely I was able to get in today using a regular account (the Panel app came up fine). But when I ran Panel using root account I got the following errors:
libpng error: Read error

and in the dialog box
Application "Panel" has crashed due to a fatal error (segmentation fault).

and after closing the dialog box in the terminal window:
Warning: File applet_widget.c: Line 934. CORBA Exception type=2, exid=IDL:CORBA/COMM_FAILURE:1.0

Can not start CORBA.

I am having the same exact problem under 7.2. When it crashes for one user, it removes itself from the startup for that user. Create a new user and it works fine for the new user, until it crashes then its removed from their startup.

Is there a config file somewhere that I can modify what starts up at boot time? For GNome that is.

RH 7.2 Gnome Panel Crash
I have experienced this problem many times, but I always get it working again with some fiddling ( I use KDE, partly because of this problem).

One thing that seems to help is to remove the gnome settings entirely so they are regenerated:

rm -rf ~/.gnome

But don't forget to move anything important from your desktop folder or whatever before doing that :^)

Also, doing this seems to have some affect (but not always):

switchdesk twm
switchdesk gnome

If all else fails, repeat the above strategies a couple times, and your gnome panel should start functioning until the next time the panel decides to crash.

Here is a more permanent solution (this is supposed to be funny):

switchdesk kde

hope this helps!

i had this problem too. also nautilus doesn't always start with system is rebooted (not often - only when installing new hardware:)

redhat 7.2

Panel crash
I have had the same problem with RedHat 7.2. I have loaded on at least six different machines (from Dell laptops to old PII's) and all show the same symptom. In each case after giving the logon name and password, the system tries
to start loading the panel program and crashes. I can always recover using CTRL/ALT/Backspace to restart X and it
will generally work the second time. Resetting the machine is a lethal no=no. In every case after this panel crash.
a reset will result in a totally corrupted file system. These machines were all running 7.0 ok. Does anyone have any
thoughts on the problem. It is difficult to debug as the panel bar disappears and I cannot open a terminal session.

possible troubleshooting plan
Here is a possible way to troubleshoot this problem: Take a snapshot of ~/.gnome while it is working propertly, and another snapshot while the panel is crashing. Then analyze all files for differences using diff or something.

another way to fix it

switchdesk wmaker

zmedico 03-11-2002 01:47 PM

possible fix
first ( to kill XFree86 as mentioned by another poster):

then, to fix the problem:

rm -f ~/.gnome/metadata.db

Try that and see if it works

or maybe the problem is in the ~/.gnome/panel.d directory?

looks like there is a duplicate thread here:

I have the same exact problem as root with Red Hat 7.2: My GNOME panel vanishes. When I use a regular account it is very, very happy... Instead of trying to troubleshoot this problem and lose my sanity, can anybody please tell me how can I upgrade my GNOME panel? :-)

I am a total newbie so please have some mercy... :-)



P.S. What will happen with the GNOME panel of the other user of my computer once I upgrade it?

Panel & no Nautilus
Please add me to the list but I only had the problem on the laptop (on the pc, never). Then I decided to reinstall my RedHat 7.2 with KDE and no GNOME. There had been 3 weeks and so far no problem on my laptop but if it happens again I will be posting here.:eek:

daacosta 08-05-2002 04:59 PM

I haven't had a problem with KDE either but I much rather have GNOME than KDE. A friend told me that just by re-installing GNOME or upgrading GNOME things were going to be copacetic... However, I don't know how to do that just yet.

:D :D

Have fun!

Re: crashed panel!!!!
open a terminal -> type panel &

And there goes ur Panel.

what version are you using?

maybe just upgrade to a newer version of gnome?

it seems like overkill to keep reinstalling linux.

if it is not every user with a problem, removing the users ~/. files pertaining to the failing app will fix the problem

if it's every user with a problem then you may want to try and reinstall gnome.
