I've managed to install Gnome 3 on Debian testing. However, it is just running in fallback-mode.

When want to start mutter or gnome-shell, there seems to be a problem with Clutter:

# mutter --replace
failed to create drawable

(mutter:32069): Clutter-CRITICAL **: Unable to initialize Clutter: Unable to select the newly created GLX context
Fensterverwalter-Fehler:Unable to initialize Clutter.

# gnome-shell --replace
failed to create drawable

(gnome-shell:32182): Clutter-CRITICAL **: Unable to initialize Clutter: Unable to select the newly created GLX context
Fensterverwalter-Fehler:Unable to initialize Clutter.

(Fensterverwalter-Fehler is german and means window-manager error)

I know it's not a hardware-issue as I used mutter (and even gnome-shell on another installation) on this notebook.

How can I find out which setting is wrong or which package is missing?

Thank you in advance!

[edit]

Could gdm be the source of this problem?

Because I have gdm (not gdm3) installed. When I install gdm3 the login screen doesn't show me a field to select or input my username, therefore I can't log in.

Related observations . . .I have an Eee PC running a Debian-derived system with Gnome. Shortly before my recent upgrade I was able to use mutter --replace and compiz --replace Then after installing gdm3 to replace gdm and upgrading a load of gnome elements i'm no longer able to do so - ICE WM still works and a note in gdm3 log mentions using .XAuthority and .IceAuthority making it incompatible with some Windows Managers.

My clutter-based programs still work and I'm hoping to find a way to have a 'classic' gnome desktop based on mutter/ clutter while still keeping up to date with the rest of the Gnome world. All this after a successful series of updates( having pinned some problematic packages) and ending with the installation of gdm3. I hope it will be possible to make a classic look( failsafe) while still being able to use graphics acceleration. I hope you got your problem fixed and look forward to continuig my mutter/clutter experiments on top of a gnome3 system.

I'm getting this error with my own python-clutter code. I believe it's due to the graphics stack. I'm running an ATI card, which has 3 options:

  1. Proprietary driver. This doesn't actually support my card any more (Radeon 9200), and anyway it's proprietary.
  2. Free driver with proprietary firmware. This gives me 3D but is completely buggy and unusable (leaves artifacts everywhere when rendering 2D, i.e. all of my desktop usage). Plus it's proprietary.
  3. Free driver with no proprietary firmware. This is what I run, and it works fine for 2D but not so for 3D. I think my lack of 3D support for my hardware is causing this issue. Note that some distros might work and others not on the same machine, since some bundle non-free firmware and even non-free drivers.
