the white (or gray/grey) screen

Description of problem:

In am not able to reach anaconda's main hub, but only on a certain KVM GUEST.
I don't know why yet.

I tried:

* Increased memory from 1GB to 2GB
* Changed display from SPICE/QLX to VNC/CIRRUS

No efect.

Issue:  After 'i accept my fate', the screen remains empty (white/gray) as shown in the screenshot.

Update: I tried with F18b TC2 and it is the same.

Version-Release number of selected component (if applicable):
F18b TC1 & TC2

How reproducible:
always (with this kvm guest)

Steps to Reproduce:
1. boot
2. accept 'fate'
Actual results:
no main hub, installing is not possible

Expected results:
main hub

Additional Info:

The anaconda is not hung, the mouse works, alt+tab works (nothing to switch to), alt+vt works. It just does not display the main hub. :-(

I can confirm this issue on F18 Beta TC1 Live KDE running on Thinkpad T410 (with nvidia graphics card)

Comment 6 Chris Lumens 2012-10-05 10:38:50 EDT
Can we see /tmp/X.log as well?

Comment 8 Chris Lumens 2012-10-05 11:14:04 EDT
My guess is we're hung in anaconda waiting for something - who knows what.  Unless we can reliably reproduce this here to step through, or you feel like doing the debugging, though, I'm not optimistic.
Comment 9 Reartes Guillermo 2012-10-05 11:45:03 EDT
I tried install gdb (to generate a core dump from anaconda) to the booted dvd but it was not possible because yum fails with a 'no module named yumain'.

So no gdb and no core dump.
Also there is no ifconfig on the dvd... not sure if a bug-report is needed for those or is it by design.
Comment 10 Daniel Vrátil 2012-10-08 10:42:20 EDT
I can reliably reproduce the issue with F18 Beta TC2 KDE in VirtualBox.

Is there any way I can provide debug information? Is a GDB stacktrace of the Python process enough, or is there any Python version of GDB?
Comment 11 Chris Lumens 2012-10-08 10:49:48 EDT
There's something called pdb for python, but the way I would approach debugging with that is to insert the following lines somewhere where the hub is getting set up:

import pdb

Then switch over to tty1 when you know those lines get hit and start stepping through the code.  Really, it would be easiest if I could reproduce this.
Comment 12 Reartes Guillermo 2012-10-09 21:34:51 EDT
I was able to reach the main hub with F18b TC3 and the same guest.
Just in case i tested with both SPICE/QLX and VNC/Cirrus. 

So, either it was fixed or it does not happen anymore with F18b TC3.
Comment 13 Chris Lumens 2012-10-10 08:48:07 EDT
Unless everyone's now seeing success, I still think this is intermittent enough to be left open.
Comment 14 Daniel Vrátil 2012-10-10 09:19:38 EDT
I found out that my problem is caused by an oxygen-gtk3 issue in the KDE spin and is unrelated to the original problem reported here.
