Description Stéphane Démurget 2011-02-05 17:29:11 EST
Description of problem:

Using the test day i686 iso with the nouveau driver, the classical gnome session is started. But when I use 'gnome-shell --replace' directly in a terminal after being logged in, everything works like a charm. The animations are really smooth and I completed all the other tests of the Gnome3 TestDay successfully under gnome-shell.

Maybe my graphic card (an NV34M GeForce FX Go5200 32M/64M) is blacklisted?
Or there is a delay to test 3d support and I used a DVD?

Can I test something else to find out why the gnome-shell session was not picked up?

Version-Release number of selected component (if applicable):

Gnome3 Alpha Test Day i686 iso.

How reproducible:

Steps to Reproduce:
1. Boot with the iso burnt on a dvd.
2. Login using the livecd user through gdm
Actual results:
Classical gnome 3 (panel + nautilus) is started.

Expected results:
Gnome-shell should be started.

I have the same issue with my Rawhide desktop ATM. It uses a [GeForce 9400 GT] [10de:0641]. Boot gives me fallback mode, but gnome-shell --replace gives me a perfectly working Shell. This hasn't always happened; a month or so back, it'd boot happily straight to shell. Looks like some of the fallback heuristics are a bit too trigger-happy. Attaching glxinfo in case it helps.

~/.xsession-errors shows:

[adamw@adam ~]$ grep acceler .xsession-errors
gnome-session[2087]: WARNING: Had to kill '/usr/libexec/gnome-session-is-accelerated' helper
[adamw@adam ~]$ 

if I run it manually after logging in, it runs and exits very quickly.

this is probably a case of 679326, which has more detail though it's a 'later' report.
