Red Hat Bugzilla – Bug 446045
GUI/VNC installs not working. exits when gtk.main() is called
Last modified: 2010-10-22 20:55:13 EDT
Description of problem:
GUI/VNC installs are not working.
Version-Release number of selected component (if applicable):
100% with GUI/VNC
Steps to Reproduce:
1. start the installation (GUI/VNC)
2. proceed to stage 2
X server starts. You can see the mouse cursor. Right after that the installation
shuts down. GUI/VNC installations fail.
X server starts and the installation proceeds with GUI or VNC.
Does not affect text mode installs. Same behavior on different arches, bare
metal and xen guest.

It is possible that this is not directly related to the Xserver as anaconda
tells us that is started successfully. The report also states that the mouse
cursor showed up, which is a good sign that the Xserver was started successfully.
1) I saw the text messages indicating anaconda is starting
2) Then black screen for some time until X starts
3) Then I saw the welcome screen
4) Then (I think) follows the partitioning screen but before it the installation
began to shut down
mzazrivec indicates that this could be related to:
Anaconda team what's your opinion?
Doesn't seem too likely that the bugs are related, though I won't rule it out
completely. Can you grab the /tmp/ramfs/X.log file and attach it to this bug?
You may need to add the nokill command line option so you still have a shell on
tty2 when we abort the install. If something in X is segfaulting, that file
should contain the reason why.
ok, I debugged this and it is unquestionably gtk. the installer goes bum when
gtk.main() is called. Going bum means something happens internally in gtk that
makes the anaconda thread exit, in turn making the whole installation exit.
I wonder if this has anything to do with 222301.
I'm not going to clone with 222301 as I am not sure that they are the same
issue. I will however, change the component to gtk2.

I don't think it'll help though.
The X server starts fine with nice background and initialized mouse pointer and
stays that way for a few seconds, you don't get any widgets though (everything
goes south after that).
The stacktrace makes it pretty clear that it must be related to the patch that
was committed in bug 222301. I'm at a loss why, though, and would like to talk
to Behdad about it. The patch changes to the code to be identical to what we
ship in current Fedora, and it works fine there...
Have you verified that the crashes go away if you back down gtk2 ? If so, I
would recommend that we back out the patch for 222301 until we have a clear
understanding of what is going on here. That patch was a bit of a last-minute

I can confirm that with gtk2-2.4.13-24.el4 and anaconda-10.1.1.89-1
the GUI and VNC installs are working.
devel_ack for the rollback.
for clarification ... it looks like we fixed the root issue instead of rolling
back the fix that introduced this bug
* Sun May 13 2007 Behdad Esfahbod <email@example.com> - 2.4.13-24.el4
- Another try, fix serial overflow in x11-geometry.
- Resolves: #222301
RHEL4-U7-re20080507.0 had gtk2-2.4.13-23.el4 which contained fix for bug #222301.
The problem was that fix for bug #222301 also introduced regression (gtk2
applications randomly segfaulting). Anaconda sure did pick up this version
of gtk2, which resulted into graphical installation being broken. The
implications of this regression were much more serious though -- whole
gnome-session and all gtk2 applications were unusable.
Anyway the problem was being taken care of in bug #222301 already
and we have a new version (2.4.13-24.el4), which works just fine
So to sum up, no rollback is needed. This bugzilla is just confusing.
